This rule reports + type declarations which do not match the regex that applies to their + specific kind (e.g. enum or interface). Each regex can be configured through + properties.

By default, this rule uses the standard Java naming convention (Pascal case).

The rule can detect utility classes and enforce a different naming convention + on those. E.g. setting the property utilityClassPattern to + [A-Z][a-zA-Z0-9]+(Utils?|Helper|Constants) reports any utility class, whose name + does not end in "Util(s)", "Helper" or "Constants".

For this rule, a utility class is defined as: a concrete class that does not + inherit from a super class or implement any interface and only has static fields + or methods.

This rule detects test classes using the following convention: Test classes are top-level classes, that + either inherit from JUnit 3 TestCase or have at least one method annotated with the Test annotations from + JUnit4/5 or TestNG.

Example

// This is Pascal case, the recommended naming convention in Java
+// Note that the default values of this rule don't allow underscores
+// or accented characters in type names
+public class FooBar {}

// You may want abstract classes to be named 'AbstractXXX', +// in which case you can customize the regex for abstract +// classes to 'Abstract[A-Z]\w+' +public abstract class Thing {}

varargs(new String[]{"a"});
+ it is not clear whether you intended the method to receive the value new Object[]{ new String[] {"a"} } or + just new String[] {"a"} (the latter happens). This confusion occurs because String[] is both a subtype + of Object[] and of Object. To clarify your intent in this case, use a cast or pass individual elements like so: +
// varargs call
+            // parm will be new Object[] { "a" }

+ + LambdaCanBeMethodReference + Lambda can be method reference + category/java/codestyle.xml/LambdaCanBeMethodReference + MAJOR + This rule reports lambda expressions that can be written more succinctly as a method reference. This is the case if the lambda is an expression lambda that only calls one method, passing the entire lambda parameter list in order to the method. For instance: +
x -> Foo.call(x) // can be Foo::call
+                x -> call(x)     // can be this::call, if call is an instance method
+                (x, y, z) -> call(x, y, z) // can be this::call
+                () -> foo.get() // can be foo::get
+                x -> x.foo()    // can be XType::foo (where XType is the type of x)

In some cases rewriting a lambda to a method reference can change the semantics of the code. For instance in (x) -> someVar.call(x), the invocation of the lambda may produce a NullPointerException (NPE) if someVar is null. The method reference someVar::call will also NPE if someVar is null, but it will do so at the point the method reference is created, while the lambda is created without error and its NPE is only thrown if the lambda is invoked (which may be never). Code should probably not rely on this subtle semantic difference, therefore these potentially problematic lambdas are also reported by default. This behavior can be disabled by setting the property ignoreIfMayNPE to true.

The property ignoreIfMayNPE is true by default. By default, calls whose receiver is itself a method call are ignored, because they could cause side effects. This may be changed by setting the property ignoreIfReceiverIsMethod to false.

Scope limitations: + - This rule will not report lambdas of the form x -> new CtorCall().something(x), because the semantics of the method reference would be to create a single new object, while the lambda creates one object per invocation. + - The rule cannot know if the qualifier of a method call performs side effects. This means (x) -> sideEffectingMethod().foo(x) will be reported. Suppress the warning in this case.

Example

import java.util.stream.Stream;

public class LambdaCanBeMethodReference { + static { + Stream.of("abc", "d") + .mapToInt(s -> s.length()) // could be String::length + .reduce((x, y) -> Integer.sum(x, y)) // could be Integer::sum + .getAsInt(); + } + }

+ + LawOfDemeter + Law of demeter + category/java/design.xml/LawOfDemeter + MAJOR + The law of Demeter is a simple rule that says "only talk to friends". It forbids +fetching data from "too far away", for some definition of distance, in order to +reduce coupling between classes or objects of different levels of abstraction.

The rule uses a notion of "degree", that quantifies how "far" an object is. +Expressions with too high degree can only be used in certain ways. The degree of +an expression is defined inductively: +- The degree of this is 0 +- The degree of a method parameter is 1 +- The degree of a new object created in a method is 1 +- The degree of a static variable is 1 +- The degree of a field access expression like expr.field is the degree of expr plus 1 +- The degree of a "getter expression" like expr.getFoo() is the degree of expr plus 1 +- The degree of a "transformation expression" like expr.withFoo("") is the degree of expr +- The degree of a variable is the maximum degree of all the assignments that reach it

Intuitively, the more you call getters, the more the degree increases. Eventually +the degree reaches the report threshold (property trustRadius) and the expression +is reported. The details of the calculation are more involved and make room for common +patterns, like usage of collections (objects that are in a list or array have the +same degree as their container), the builder pattern, and getters that do not appear +to break a boundary of abstraction.

Be aware that this rule is prone to many false-positives and low-priority warnings. +You can increase the trustRadius property to reduce them drastically. The default +trustRadius of 1 corresponds to the original law of Demeter (you're only allowed +one getter call on untrusted values). Given some trustRadius value: +- expressions of degree lower or equal to trustRadius are not reported +- expressions of degree exactly trustRadius + 1 are reported, unless they are only returned +from the current method, or passed as argument to another method. Without this exception it +would not be possible to extract any information from e.g. method parameters. +- values of degree strictly greater than trustRadius + 1 are not reported. The +intuition is that to obtain a value of degree n > 1 then you must use an expression +of degree n - 1, so if you have n > trustRadius + 1, there you're using some value +of degree trustRadius + 1 that will be reported.

Some variables cannot be declared close to their first usage because of side-effects +occurring before they're first used. We try to avoid reporting those by considering +most method and constructor invocations to be impure. See the second example.

To preserve the stack trace, the original exception may be used as the cause of +the new exception, using Throwable#initCause, or passed as a constructor argument +to the new exception.

+ + UseExplicitTypes + Use explicit types + category/java/codestyle.xml/UseExplicitTypes + MAJOR + Java 10 introduced the var keyword. This reduces the amount of code written because java can infer the type +from the initializer of the variable declaration.

This is essentially a trade-off: On the one hand, it can make code more readable by eliminating redundant +information. On the other hand, it can make code less readable by eliding useful information. There is no +blanket rule for when var should be used or shouldn't.

It may make sense to use var when the type is inherently clear upon reading the statement +(ie: assignment to either a literal value or a constructor call). Those use cases +can be enabled through properties.

Notice that lambda parameters are allowed, as they are already inferred by default (the var keyword +is completely optional).

+ + UseLocaleWithCaseConversions + Use locale with case conversions + category/java/errorprone.xml/UseLocaleWithCaseConversions + MAJOR + When doing String::toLowerCase()/toUpperCase() conversions, use an explicit locale argument to specify the case +transformation rules.

Using String::toLowerCase() without arguments implicitly uses Locale::getDefault(). +The problem is that the default locale depends on the current JVM setup (and usually on the system in which +it is running). Using the system default may be exactly what you want (e.g. if you are manipulating strings +you got through standard input), but it may as well not be the case (e.g. if you are getting the string over +the network or a file, and the encoding is well-defined and independent of the environment). In the latter case, +using the default locale makes the case transformation brittle, as it may yield unexpected results on a machine +whose locale has other case translation rules. For example, in Turkish, the uppercase form of i is İ (U+0130, +not ASCII) and not I (U+0049) as in English.

The rule is intended to force developers to think about locales when dealing with strings. By taking a +conscious decision about the choice of locale at the time of writing, you reduce the risk of surprising +behaviour down the line, and communicate your intent to future readers.

Example

// violation - implicitly system-dependent conversion
+if (x.toLowerCase().equals("list")) {}

// The above will not match "LIST" on a system with a Turkish locale. +// It could be replaced with +if (x.toLowerCase(Locale.US).equals("list")) { } +// or simply +if (x.equalsIgnoreCase("list")) { }

// ok - system independent conversion +String z = a.toLowerCase(Locale.ROOT);

// ok - explicit system-dependent conversion +String z2 = a.toLowerCase(Locale.getDefault());

Some parentheses that strictly speaking are unnecessary, may still be considered useful + for readability. This rule allows to ignore violations on two kinds of unnecessary parentheses: + - "Clarifying" parentheses, which separate operators of difference precedence.

This can occur when an array is passed as a single varargs argument, when the array type is not exactly the type of array that the varargs method expects.

Test methods are identified category/java/codestyle.xml/LambdaCanBeMethodReference MAJOR This rule reports lambda expressions that can be written more succinctly as a method reference. This is the case if the lambda is an expression lambda that only calls one method, passing the entire lambda parameter list in order to the method. For instance: -

x -> Foo.call(x) // can be Foo::call
-                x -> call(x)     // can be this::call, if call is an instance method
-                (x, y, z) -> call(x, y, z) // can be this::call

-                x -> x.foo()    // can be XType::foo (where XType is the type of x)

In some cases rewriting a lambda to a method reference can change the semantics of the code. For instance in (x) -> someVar.call(x), the invocation of the lambda may produce a NullPointerException (NPE) if someVar is null. The method reference someVar::call will also NPE if someVar is null, but it will do so at the point the method reference is created, while the lambda is created without error and its NPE is only thrown if the lambda is invoked (which may be never). Code should probably not rely on this subtle semantic difference, therefore these potentially problematic lambdas are also reported by default. This behavior can be disabled by setting the property ignoreIfMayNPE to true.

The property ignoreIfMayNPE is true by default. By default, calls whose receiver is itself a method call are ignored, because they could cause side effects. This may be changed by setting the property ignoreIfReceiverIsMethod to false.

Using String::toLowerCase() without arguments implicitly uses Locale::getDefault(). The problem is that the default locale depends on the current JVM setup (and usually on the system in which it is running). Using the system default may be exactly what you want (e.g. if you are manipulating strings you got through standard input), but it may as well not be the case (e.g. if you are getting the string over the network or a file, and the encoding is well-defined and independent of the environment). In the latter case, using the default locale makes the case transformation brittle, as it may yield unexpected results on a machine whose locale has other case translation rules.

category/java/codestyle.xml/LambdaCanBeMethodReference MAJOR This rule reports lambda expressions that can be written more succinctly as a method reference. This is the case if the lambda is an expression lambda that only calls one method, passing the entire lambda parameter list in order to the method. For instance: -
 x -> Foo.call(x) // can be Foo::call
+            
 x -> Foo.call(x) // can be Foo::call
                  x -> call(x)     // can be this::call, if call is an instance method

+ x -> x.foo() // can be XType::foo (where XType is the type of x)

In some cases rewriting a lambda to a method reference can change the semantics of the code. For instance in (x) -> someVar.call(x), the invocation of the lambda may produce a NullPointerException (NPE) if someVar is null. The method reference someVar::call will also NPE if someVar is null, but it will do so at the point the method reference is created, while the lambda is created without error and its NPE is only thrown if the lambda is invoked (which may be never). Code should probably not rely on this subtle semantic difference, therefore these potentially problematic lambdas are also reported by default. This behavior can be disabled by setting the property ignoreIfMayNPE to true.

The property ignoreIfMayNPE is true by default. By default, calls whose receiver is itself a method call are ignored, because they could cause side effects. This may be changed by setting the property ignoreIfReceiverIsMethod to false.

Limitations: * The rule currently cannot know which method calls throw exceptions, or which exceptions they throw.

Limitations:

  • The rule currently cannot know which method calls throw exceptions, or which exceptions they throw.
  • In the body of a try block, every method or constructor call is assumed to throw. This may cause false-negatives. The only other language construct that is assumed to throw is the throw statement, in particular, things like assert statements, or NullPointerExceptions on dereference are ignored.
  • The rule cannot resolve assignments across constructors, when they're called with the special
  • this(...) syntax. This may cause false-negatives.

Both of those limitations may be partly relaxed in PMD 7.

x -> x.foo() // can be XType::foo (where XType is the type of x)

In some cases rewriting a lambda to a method reference can change the semantics of the code. For instance in (x) -> someVar.call(x), the invocation of the lambda may produce a NullPointerException (NPE) if someVar is null. The method reference someVar::call will also NPE if someVar is null, but it will do so at the point the method reference is created, while the lambda is created without error and its NPE is only thrown if the lambda is invoked (which may be never). Code should probably not rely on this subtle semantic difference, therefore these potentially problematic lambdas are also reported by default. This behavior can be disabled by setting the property ignoreIfMayNPE to true.

The property ignoreIfMayNPE is true by default. By default, calls whose receiver is itself a method call are ignored, because they could cause side effects. This may be changed by setting the property ignoreIfReceiverIsMethod to false.

-

Scope limitations: - - This rule will not report lambdas of the form x -> new CtorCall().something(x), because the semantics of the method reference would be to create a single new object, while the lambda creates one object per invocation. - - The rule cannot know if the qualifier of a method call performs side effects. This means (x) -> sideEffectingMethod().foo(x) will be reported. Suppress the warning in this case.

The law of Demeter is a simple rule that says "only talk to friends". It forbids fetching data from "too far away", for some definition of distance, in order to reduce coupling between classes or objects of different levels of abstraction.

-

The rule uses a notion of "degree", that quantifies how "far" an object is. -Expressions with too high degree can only be used in certain ways. The degree of -an expression is defined inductively: -- The degree of this is 0 -- The degree of a method parameter is 1 -- The degree of a new object created in a method is 1 -- The degree of a static variable is 1 -- The degree of a field access expression like expr.field is the degree of expr plus 1 -- The degree of a "getter expression" like expr.getFoo() is the degree of expr plus 1 -- The degree of a "transformation expression" like expr.withFoo("") is the degree of expr -- The degree of a variable is the maximum degree of all the assignments that reach it

+

The rule uses a notion of "degree", that quantifies how "far" an object is.Expressions with too high degree can only be used in certain ways. The degree ofan expression is defined inductively:

  • The degree of this is 0
  • The degree of a method parameter is 1
  • The degree of a new object created in a method is 1
  • The degree of a static variable is 1
  • The degree of a field access expression like expr.field is the degree of expr plus 1
  • The degree of a "getter expression" like expr.getFoo() is the degree of expr plus 1
  • The degree of a "transformation expression" like expr.withFoo("") is the degree of expr
  • The degree of a variable is the maximum degree of all the assignments that reach it

Intuitively, the more you call getters, the more the degree increases. Eventually the degree reaches the report threshold (property trustRadius) and the expression is reported. The details of the calculation are more involved and make room for common patterns, like usage of collections (objects that are in a list or array have the same degree as their container), the builder pattern, and getters that do not appear to break a boundary of abstraction.

-

Be aware that this rule is prone to many false-positives and low-priority warnings. -You can increase the trustRadius property to reduce them drastically. The default -trustRadius of 1 corresponds to the original law of Demeter (you're only allowed -one getter call on untrusted values). Given some trustRadius value: -- expressions of degree lower or equal to trustRadius are not reported -- expressions of degree exactly trustRadius + 1 are reported, unless they are only returned -from the current method, or passed as argument to another method. Without this exception it -would not be possible to extract any information from e.g. method parameters. -- values of degree strictly greater than trustRadius + 1 are not reported. The -intuition is that to obtain a value of degree n > 1 then you must use an expression -of degree n - 1, so if you have n > trustRadius + 1, there you're using some value -of degree trustRadius + 1 that will be reported.

Please note: - - The rule will report those suppressions comments/annotations that did not suppress a violation - _during the current run_. That means you cannot run this rule separately from other rules, it must - always be run with all the rules that could produce a warning. This is most likely not a problem, as - you can just include this rule in your regular ruleset. - - The rule for now only reports annotations specific to PMD, like @SuppressWarnings("PMD"). For instance - @SuppressWarnings("all") is never reported as we cannot know if another tool is producing a - warning there that must be suppressed. In the future we might be able to check for other common ones - like @SuppressWarnings("unchecked") or "fallthrough".

Be aware that this rule is prone to many false-positives and low-priority warnings.You can increase the trustRadius property to reduce them drastically. The defaulttrustRadius of 1 corresponds to the original law of Demeter (you're only allowedone getter call on untrusted values). Given some trustRadius value:

  • expressions of degree lower or equal to trustRadius are not reported
  • expressions of degree exactly trustRadius + 1 are reported, unless they are only returned
  • from the current method, or passed as argument to another method. Without this exception it would not be possible to extract any information from e.g. method parameters.
  • values of degree strictly greater than trustRadius + 1 are not reported. The
  • intuition is that to obtain a value of degree n > 1 then you must use an expression of degree n - 1, so if you have n > trustRadius + 1, there you're using some value of degree trustRadius + 1 that will be reported.

    In some cases rewriting a lambda to a method reference can change the semantics of the code. For instance in (x) -> someVar.call(x), the invocation of the lambda may produce a NullPointerException (NPE) if someVar is null. The method reference someVar::call will also NPE if someVar is null, but it will do so at the point the method reference is created, while the lambda is created without error and its NPE is only thrown if the lambda is invoked (which may be never). Code should probably not rely on this subtle semantic difference, therefore these potentially problematic lambdas are also reported by default. This behavior can be disabled by setting the property ignoreIfMayNPE to true.

    The property ignoreIfMayNPE is true by default. By default, calls whose receiver is itself a method call are ignored, because they could cause side effects. This may be changed by setting the property ignoreIfReceiverIsMethod to false.

    Scope limitations:

    • This rule will not report lambdas of the form x -> new CtorCall().something(x), because the semantics of the method reference would be to create a single new object, while the lambda creates one object per invocation.
    • The rule cannot know if the qualifier of a method call performs side effects. This means (x) -> sideEffectingMethod().foo(x) will be reported. Suppress the warning in this case.

    The law of Demeter is a simple rule that says "only talk to friends". It forbids fetching data from "too far away", for some definition of distance, in order to reduce coupling between classes or objects of different levels of abstraction.

    -

    The rule uses a notion of "degree", that quantifies how "far" an object is.Expressions with too high degree can only be used in certain ways. The degree ofan expression is defined inductively:

    • The degree of this is 0
    • The degree of a method parameter is 1
    • The degree of a new object created in a method is 1
    • The degree of a static variable is 1
    • The degree of a field access expression like expr.field is the degree of expr plus 1
    • The degree of a "getter expression" like expr.getFoo() is the degree of expr plus 1
    • The degree of a "transformation expression" like expr.withFoo("") is the degree of expr
    • The degree of a variable is the maximum degree of all the assignments that reach it

    • The degree of this is 0

    • The degree of a "transformation expression" like expr.withFoo("") is the degree of expr
    • The degree of a variable is the maximum degree of all the assignments that reach it

    Intuitively, the more you call getters, the more the degree increases. Eventually the degree reaches the report threshold (property trustRadius) and the expression is reported. The details of the calculation are more involved and make room for common patterns, like usage of collections (objects that are in a list or array have the same degree as their container), the builder pattern, and getters that do not appear to break a boundary of abstraction.

    -

    Be aware that this rule is prone to many false-positives and low-priority warnings.You can increase the trustRadius property to reduce them drastically. The defaulttrustRadius of 1 corresponds to the original law of Demeter (you're only allowedone getter call on untrusted values). Given some trustRadius value:

    • expressions of degree lower or equal to trustRadius are not reported
    • expressions of degree exactly trustRadius + 1 are reported, unless they are only returned
    • from the current method, or passed as argument to another method. Without this exception it would not be possible to extract any information from e.g. method parameters.
    • values of degree strictly greater than trustRadius + 1 are not reported. The
    • intuition is that to obtain a value of degree n > 1 then you must use an expression of degree n - 1, so if you have n > trustRadius + 1, there you're using some value of degree trustRadius + 1 that will be reported.

    • "Clarifying" parentheses, which separate operators of difference precedence. While unnecessary, they make precedence rules explicit, which may be useful for rarely used operators. For example:

    In some cases rewriting a lambda to a method reference can change the semantics of the code. For instance in (x) -> someVar.call(x), the invocation of the lambda may produce a NullPointerException (NPE) if someVar is null. The method reference someVar::call will also NPE if someVar is null, but it will do so at the point the method reference is created, while the lambda is created without error and its NPE is only thrown if the lambda is invoked (which may be never). Code should probably not rely on this subtle semantic difference, therefore these potentially problematic lambdas are also reported by default. This behavior can be disabled by setting the property ignoreIfMayNPE to true.

That means you cannot run this rule separately from other rules, it must always be run with all the rules that could produce a warning. This is most likely not a problem, as you can just include this rule in your regular ruleset.
    • The rule for now only reports annotations specific to PMD, like @SuppressWarnings("PMD"). For instance @SuppressWarnings("all") is never reported as we cannot know if another tool is producing a warning there that must be suppressed. In the future we might be able to check for other common ones like @SuppressWarnings("unchecked") or "fallthrough".

    x -> x.foo() // can be XType::foo (where XType is the type of x)

    In some cases rewriting a lambda to a method reference can change the semantics of the code. For instance in (x) -> someVar.call(x), the invocation of the lambda may produce a NullPointerException (NPE) if someVar is null. The method reference someVar::call will also NPE if someVar is null, but it will do so at the point the method reference is created, while the lambda is created without error and its NPE is only thrown if the lambda is invoked (which may be never). Code should probably not rely on this subtle semantic difference, therefore these potentially problematic lambdas are also reported by default. This behavior can be disabled by setting the property ignoreIfMayNPE to true.

    The property ignoreIfMayNPE is true by default. By default, calls whose receiver is itself a method call are ignored, because they could cause side effects. This may be changed by setting the property ignoreIfReceiverIsMethod to false.

    The law of Demeter is a simple rule that says "only talk to friends". It forbids fetching data from "too far away", for some definition of distance, in order to reduce coupling between classes or objects of different levels of abstraction.

    • The degree of this is 0
    • The degree of a method parameter is 1
    • The degree of a new object created in a method is 1
    • The degree of a static variable is 1
    • The degree of a field access expression like expr.field is the degree of expr plus 1

    • The degree of a "transformation expression" like expr.withFoo("") is the degree of expr
    • The degree of a variable is the maximum degree of all the assignments that reach it

    +

    The rule uses a notion of "degree", that quantifies how "far" an object is. Expressions with too high degree can only be used in certain ways. The degree of an expression is defined inductively:

    +
    • The degree of this is 0
    • The degree of a method parameter is 1

    • The degree of a variable is the maximum degree of all the assignments that reach it

    Intuitively, the more you call getters, the more the degree increases. Eventually the degree reaches the report threshold (property trustRadius) and the expression is reported. The details of the calculation are more involved and make room for common patterns, like usage of collections (objects that are in a list or array have the same degree as their container), the builder pattern, and getters that do not appear to break a boundary of abstraction.

    -

    • expressions of degree lower or equal to trustRadius are not reported
    • expressions of degree exactly trustRadius + 1 are reported, unless they are only returned from the current method, or passed as argument to another method. Without this exception it would not be possible to extract any information from e.g. method parameters.
    • values of degree strictly greater than trustRadius + 1 are not reported. The intuition is that to obtain a value of degree n > 1 then you must use an expression of degree n - 1, so if you have n > trustRadius + 1, there you're using some value of degree trustRadius + 1 that will be reported.

    Be aware that this rule is prone to many false-positives and low-priority warnings. You can increase the trustRadius property to reduce them drastically.

    - One might assume that the result of new BigDecimal(0.1) is exactly equal to 0.1, but it is - actually equal to .1000000000000000055511151231257827021181583404541015625. This is because 0.1 - cannot be represented exactly as a double (or as a binary fraction of any finite length). - Thus, the long value that is being passed in to the constructor is not exactly equal to 0.1, appearances notwithstanding. -

    -

    - The (String) constructor, on the other hand, is perfectly predictable: new BigDecimal("0.1") is exactly equal - to 0.1, as one would expect. Therefore, it is generally recommended that the (String) constructor be used in preference to this one. -

    - Calls to a collection’s toArray(E[]) method should specify a target array of zero size. This allows the - JVM to - optimize the memory allocation and copying as much as possible. -

    -

    - Previous versions of this rule (pre PMD 6.0.0) suggested the opposite, but current JVM implementations - perform always better, when they have full control over the target array. And allocation an array via - reflection is nowadays as fast as the direct allocation. -

    -

    - See also Arrays of Wisdom of the Ancients -

    -

    - Note: If you don’t need an array of the correct type, then the simple toArray() method without an array - is faster, but - returns only an array of type Object[]. -

    -

    Noncompliant Code Example

    -
    -List<Foo> foos = getFoos();
    -
    -// inefficient, the array needs to be zeroed out by the jvm before it is handed over to the toArray method
    -Foo[] fooArray = foos.toArray(new Foo[foos.size()]);
    -
    -

    Compliant Solution

    -
    -List<Foo> foos = getFoos();
    -
    -// much better; this one allows the jvm to allocate an array of the correct size and effectively skip
    -// the zeroing, since each array element will be overridden anyways
    -Foo[] fooArray = foos.toArray(new Foo[0]);

    Date: Thu, 17 Jul 2025 17:25:27 +0200
    Subject: [PATCH 387/526] removed the dependency on JavaResourceLocator and
     thus the runtime dependency on the Sonar java plugin, which results in class
     not found exceptions

        • firstOnly: Report any reassignments of the loop variable, except as the first statement in the loop body. _This is useful if some kind of normalization or clean-up of the value before using is permitted, but any other change of the variable is not._

        The abstract class does not contain any abstract methods. An abstract class suggests +an incomplete implementation, which is to be completed by subclasses implementing the +abstract methods. If the class is intended to be used as a base class only (not to be instantiated +directly) a protected constructor can be provided to prevent direct instantiation.

        Instantiation by way of private constructors from outside the constructor's class often causes the +generation of an accessor. A factory method, or non-privatization of the constructor can eliminate this +situation. The generated class file is actually an interface. It gives the accessing class the ability +to invoke a new hidden package scope constructor that takes the interface as a supplementary parameter. +This turns a private constructor effectively into one with package scope, and is challenging to discern.

        Note: This rule is only executed for Java 10 or lower. +Since Java 11, JEP 181: Nest-Based Access Control has been implemented. This +means that in Java 11 and above accessor classes are not generated anymore.

        Methods such as getDeclaredConstructors(), getDeclaredMethods(), and getDeclaredFields() also +return private constructors, methods and fields.

        One might assume that the result of "new BigDecimal(0.1)" is exactly equal to 0.1, but it is actually +equal to .1000000000000000055511151231257827021181583404541015625. +This is because 0.1 cannot be represented exactly as a double (or as a binary fraction of any finite +length). Thus, the long value that is being passed in to the constructor is not exactly equal to 0.1, +appearances notwithstanding.

        +

        The (String) constructor, on the other hand, is perfectly predictable: 'new BigDecimal("0.1")' is +exactly equal to 0.1, as one would expect. Therefore, it is generally recommended that the +(String) constructor be used in preference to this one.

         BigDecimal bd = new BigDecimal(1.123);       // loss of precision, this would trigger the rule

        The FileInputStream and FileOutputStream classes contains a finalizer method which will cause garbage +collection pauses. +See JDK-8080225 for details.

        +

        The FileReader and FileWriter constructors instantiate FileInputStream and FileOutputStream, +again causing garbage collection issues while finalizer methods are called.

        • Use Files.newInputStream(Paths.get(fileName)) instead of new FileInputStream(fileName).
        • Use Files.newOutputStream(Paths.get(fileName)) instead of new FileOutputStream(fileName).

        Please note, that the java.nio API does not throw a FileNotFoundException anymore, instead +it throws a NoSuchFileException. If your code dealt explicitly with a FileNotFoundException, +then this needs to be adjusted. Both exceptions are subclasses of IOException, so catching +that one covers both.

        Reassigning values to incoming parameters of a method or constructor is not recommended, as this can +make the code more difficult to understand. The code is often read with the assumption that parameter values +don't change and an assignment violates therefore the principle of least astonishment. This is especially a +problem if the parameter is documented e.g. in the method's javadoc and the new content differs from the original +documented content.

        +

        Use temporary local variables instead. This allows you to assign a new name, which makes the code better +understandable.

        +

        Note that this rule considers both methods and constructors. If there are multiple assignments for a formal +parameter, then only the first assignment is reported.

        +

        Example

        +

         public class Hello {

        Avoid throwing NullPointerExceptions manually. These are confusing because most people will assume that the +virtual machine threw it. To avoid a method being called with a null parameter, you may consider +using an IllegalArgumentException instead, making it clearly seen as a programmer-initiated exception. +However, there are better ways to handle this:

        +

        >Effective Java, 3rd Edition, Item 72: Favor the use of standard exceptions +> +>Arguably, every erroneous method invocation boils down to an illegal argument or state, +but other exceptions are standardly used for certain kinds of illegal arguments and states. +If a caller passes null in some parameter for which null values are prohibited, convention dictates that +NullPointerException be thrown rather than IllegalArgumentException.

        +

        To implement that, you are encouraged to use java.util.Objects.requireNonNull() +(introduced in Java 1.7). This method is designed primarily for doing parameter +validation in methods and constructors with multiple parameters.

        +

        Your parameter validation could thus look like the following: +

         public class Foo {
        +     private String exampleValue;
        +
        +     void setExampleValue(String exampleValue) {
        +       // check, throw and assignment in a single standard call
        +       this.exampleValue = Objects.requireNonNull(exampleValue, "exampleValue must not be null!");
        +     }
        +   }

        Configurable naming conventions for type declarations. This rule reports + type declarations which do not match the regex that applies to their + specific kind (e.g. enum or interface). Each regex can be configured through + properties.

        +

        By default, this rule uses the standard Java naming convention (Pascal case).

        +

        The rule can detect utility classes and enforce a different naming convention + on those. E.g. setting the property utilityClassPattern to + [A-Z][a-zA-Z0-9]+(Utils?|Helper|Constants) reports any utility class, whose name + does not end in "Util(s)", "Helper" or "Constants".

        +

        For this rule, a utility class is defined as: a concrete class that does not + inherit from a super class or implement any interface and only has static fields + or methods.

        +

        This rule detects test classes using the following convention: Test classes are top-level classes, that + either inherit from JUnit 3 TestCase or have at least one method annotated with the Test annotations from + JUnit4/5 or TestNG.

        Methods that are highly complex are difficult to read and more costly to maintain. If you include too much decisional + logic within a single method, you make its behavior hard to understand and more difficult to modify.

        +

        Cognitive complexity is a measure of how difficult it is for humans to read and understand a method. Code that contains + a break in the control flow is more complex, whereas the use of language shorthands doesn't increase the level of + complexity. Nested control flows can make a method more difficult to understand, with each additional nesting of the + control flow leading to an increase in cognitive complexity.

        To avoid mistakes if we want that an Annotation, Class, Enum, Method, Constructor or Field have a default access modifier +we must add a comment at the beginning of its declaration. +By default, the comment must be / default / or / package /, if you want another, you have to provide a regular expression.

        This rule ignores by default all cases that have a @VisibleForTesting annotation or any JUnit5/TestNG annotation. Use the +property "ignoredAnnotations" to customize the recognized annotations.

        Use equals() to compare object references; avoid comparing them with ==.

        +

        Since comparing objects with named constants is useful in some cases (eg, when +defining constants for sentinel values), the rule ignores comparisons against +fields with all-caps name (eg this == SENTINEL), which is a common naming +convention for constant fields.

        +

        You may allow some types to be compared by reference by listing the exceptions +in the typesThatCompareByReference property.

        +

         class Foo {

To test whether a + value is the NaN value, one should instead use Double.isNaN(someDouble) + (or Float.isNaN). The != operator should be treated similarly. + Finally, comparisons like someDouble <= Double.NaN are nonsensical + and will always evaluate to false.

Cast to {0} or {0}[], or pass varargs parameters separately to clarify intent. +

        Reports a confusing argument passed to a varargs method.

        +

        This can occur when an array is passed as a single varargs argument, when the array type is not exactly the + type of array that the varargs method expects. If, that array is a subtype of the component type of the expected + array type, then it might not be clear what value the called varargs method will receive. + For instance if you have: +

         void varargs(Object... parm);
        + and call it like so: +
         varargs(new String[]{"a"});
        + it is not clear whether you intended the method to receive the value new Object[]{ new String[] {"a"} } or + just new String[] {"a"} (the latter happens). This confusion occurs because String[] is both a subtype + of Object[] and of Object. To clarify your intent in this case, use a cast or pass individual elements like so: +
         // varargs call
        +             // parm will be `new Object[] { "a" }`
        +             varargs("a");
        +
        +             // non-varargs call
        +             // parm will be `new String[] { "a" }`
        +             varargs((Object[]) new String[]{"a"});
        +
        +             // varargs call
        +             // parm will be `new Object[] { new String[] { "a" } }`
        +             varargs((Object) new String[]{"a"});

        +

        Another confusing case is when you pass null as the varargs argument. Here it is not clear whether you intended + to pass an array with a single null element, or a null array (the latter happens). This can similarly be clarified + with a cast.

        +

        Example

        +

         import java.util.Arrays;
        +
        +             abstract class C {

        Reports calls to overridable methods on this during object initialization. These +are invoked on an incompletely constructed object and can be difficult to debug if overridden. +This is because the subclass usually assumes that the superclass is completely initialized +in all methods.

        +

        The complexity of methods directly affects maintenance costs and readability. Concentrating too much decisional logic +in a single method makes its behaviour hard to read and change.

        +

        Cyclomatic complexity assesses the complexity of a method by counting the number of decision points in a method, +plus one for the method entry. Decision points are places where the control flow jumps to another place in the +program. As such, they include all control flow statements, such as if, while, for, and case. For more +details on the calculation, see the documentation CYCLO.

        +

        Generally, numbers ranging from 1-4 denote low complexity, 5-7 denote moderate complexity, 8-10 denote +high complexity, and 11+ is very high complexity. By default, this rule reports methods with a complexity >= 10. +Additionally, classes with many methods of moderate complexity get reported as well once the total of their +methods' complexities reaches 80, even if none of the methods was directly reported.

        +

        Reported methods should be broken down into several smaller methods. Reported classes should probably be broken down +into subcomponents.

         class Foo {

        Data Classes are simple data holders, which reveal most of their state, and +without complex functionality. The lack of functionality may indicate that +their behaviour is defined elsewhere, which is a sign of poor data-behaviour +proximity.

        +

        Refactoring a Data Class should focus on restoring a good data-behaviour proximity.

        The method appears to be a test case since it has public or default visibility, +non-static access, no arguments, no return value, has no annotations, but is a +member of a class that has one or more JUnit test cases. If it is a utility +method, it should likely have private visibility. If it is an ignored test, it +should be annotated with @Test and @Ignore.

        When switching over an enum or sealed class, the compiler will ensure that all possible cases are covered. +If a case is missing, this will result in a compilation error.

        String.trim().length() == 0 (or String.trim().isEmpty() for the same reason) is an inefficient +way to check if a String is really blank, as it creates a new String object just to check its size. +Consider creating a static function that loops through a string, checking Character.isWhitespace() +on each character and returning false if a non-whitespace character is found. A Smarter code to +check for an empty string would be:

        Identifies beans, that don't follow the JavaBeans API specification.

        +

        Each non-static field should have both a getter and a setter method. If the field is just used internally and is not +a bean property, then the field should be marked as transient.

        +

        The rule verifies that the type of the field is the same as the result type of the getter. And that this type matches +the type used in the setter.

        +

        The rule also checks, that there is a no-arg or default constructor available.

        +

        Optionally the rule also verifies, that the bean implements java.io.Serializable. While this is a requirement for the +original JavaBeans specification, frameworks nowadays don't strictly require this anymore.

        +

        In order to avoid many false positives in classes that are not beans, the rule needs to be explicitly +enabled by configuring the property packages.

        This rule reports lambda expressions that can be written more succinctly as a method reference. This is the case if the lambda is an expression lambda that only calls one method, passing the entire lambda parameter list in order to the method. For instance: +

         x -> Foo.call(x) // can be Foo::call
        +                 x -> call(x)     // can be this::call, if call is an instance method

        +                 x -> x.foo()    // can be XType::foo (where XType is the type of x)

        +

        In some cases rewriting a lambda to a method reference can change the semantics of the code. For instance in (x) -> someVar.call(x), the invocation of the lambda may produce a NullPointerException (NPE) if someVar is null. The method reference someVar::call will also NPE if someVar is null, but it will do so at the point the method reference is created, while the lambda is created without error and its NPE is only thrown if the lambda is invoked (which may be never). Code should probably not rely on this subtle semantic difference, therefore these potentially problematic lambdas are also reported by default. This behavior can be disabled by setting the property ignoreIfMayNPE to true.

        +

        The property ignoreIfMayNPE is true by default. By default, calls whose receiver is itself a method call are ignored, because they could cause side effects. This may be changed by setting the property ignoreIfReceiverIsMethod to false.

        +

        Scope limitations:

        +
        • This rule will not report lambdas of the form x -> new CtorCall().something(x), because the semantics of the method reference would be to create a single new object, while the lambda creates one object per invocation.
        • The rule cannot know if the qualifier of a method call performs side effects. This means (x) -> sideEffectingMethod().foo(x) will be reported. Suppress the warning in this case.
        +

        Example

        +

         import java.util.stream.Stream;
        +
        +             public class LambdaCanBeMethodReference {
        +                 static {
        +                     Stream.of("abc", "d")
        +                             .mapToInt(s -> s.length()) // could be String::length
        +                             .reduce((x, y) -> Integer.sum(x, y)) // could be Integer::sum
        +                             .getAsInt();

        + + LawOfDemeter + Law of demeter + category/java/design.xml/LawOfDemeter + MAJOR + Title of issues: Potential violation of the law of Demeter ({0}) +

        The law of Demeter is a simple rule that says "only talk to friends". It forbids +fetching data from "too far away", for some definition of distance, in order to +reduce coupling between classes or objects of different levels of abstraction.

        +

        The rule uses a notion of "degree", that quantifies how "far" an object is. Expressions with too high degree can only be used in certain ways. The degree of an expression is defined inductively:

        +
        • The degree of this is 0
        • The degree of a method parameter is 1
        • The degree of a new object created in a method is 1
        • The degree of a static variable is 1
        • The degree of a field access expression like expr.field is the degree of expr plus 1
        • The degree of a "getter expression" like expr.getFoo() is the degree of expr plus 1
        • The degree of a "transformation expression" like expr.withFoo("") is the degree of expr
        • The degree of a variable is the maximum degree of all the assignments that reach it
        +

        Intuitively, the more you call getters, the more the degree increases. Eventually +the degree reaches the report threshold (property trustRadius) and the expression +is reported. The details of the calculation are more involved and make room for common +patterns, like usage of collections (objects that are in a list or array have the +same degree as their container), the builder pattern, and getters that do not appear +to break a boundary of abstraction.

        +

        Be aware that this rule is prone to many false-positives and low-priority warnings. You can increase the trustRadius property to reduce them drastically. The default trustRadius of 1 corresponds to the original law of Demeter (you're only allowed one getter call on untrusted values). Given some trustRadius value:

        +
        • expressions of degree lower or equal to trustRadius are not reported
        • expressions of degree exactly trustRadius + 1 are reported, unless they are only returned from the current method, or passed as argument to another method. Without this exception it
        • values of degree strictly greater than trustRadius + 1 are not reported. The intuition is that to obtain a value of degree n > 1 then you must use an expression
        +

        See also the references:

        + +

        Example

        +

         public class Foo {
        +     /**
        +      * This example will result in one violation.
        +      */
        +     public void example(Bar b) { // b has degree 1
        +         // `b.getC()` has degree 2, it's breaking a boundary of abstraction and so is reported.
        +         b.getC().doIt();
        +         // To respect the law of Demeter, Bar should encapsulate its
        +         // C member more properly, eg by exposing a method like this:
        +         b.callDoItOnC();
        +
        +         // a constructor call, not a method call.
        +         D d = new D();
        +         // this method call is ok, because we have create the new
        +         // instance of D locally.
        +         d.doSomethingElse();

        + + OptimizableToArrayCall + Optimizable to array call + category/java/performance.xml/OptimizableToArrayCall + MAJOR + Title of issues: This call to Collection.toArray() may be optimizable +

        Calls to a collection's toArray(E[]) method should specify a target array of zero size. This allows the JVM +to optimize the memory allocation and copying as much as possible.

        +

        Previous versions of this rule (pre PMD 6.0.0) suggested the opposite, but current JVM implementations +perform always better, when they have full control over the target array. And allocation an array via +reflection is nowadays as fast as the direct allocation.

        +

        See also Arrays of Wisdom of the Ancients

        +

        Note: If you don't need an array of the correct type, then the simple toArray() method without an array +is faster, but returns only an array of type Object[].

        +

        Example

        +

         List<Foo> foos = getFoos();
        +
        + // much better; this one allows the jvm to allocate an array of the correct size and effectively skip
        + // the zeroing, since each array element will be overridden anyways
        + Foo[] fooArray = foos.toArray(new Foo[0]);
        +
        + // inefficient, the array needs to be zeroed out by the jvm before it is handed over to the toArray method
        + Foo[] fooArray = foos.toArray(new Foo[foos.size()]);

        Checks for variables that are defined before they might be used. A declaration is +deemed to be premature if there are some statements that may return or throw an +exception between the time the variable is declared and the time it is first read.

        +

        Some variables cannot be declared close to their first usage because of side-effects +occurring before they're first used. We try to avoid reporting those by considering +most method and constructor invocations to be impure. See the second example.

        +

        Note that this rule is meant to improve code readability but is not an optimization. +A smart JIT will not care whether the variable is declared prematurely or not, as it +can reorder code.

        Reports exceptions that are thrown from within a catch block, yet don't refer to the +exception parameter declared by that catch block. The stack trace of the original +exception could be lost, which makes the thrown exception less informative.

        +

        To preserve the stack trace, the original exception may be used as the cause of +the new exception, using Throwable#initCause, or passed as a constructor argument +to the new exception. It may also be preserved using Throwable#addSuppressed. +The rule actually assumes that any method or constructor that takes the original +exception as argument preserves the original stack trace.

        +

        The rule allows InvocationTargetException and PrivilegedActionException to be +replaced by their cause exception. The discarded part of the stack trace is in those +cases only JDK-internal code, which is not very useful. The rule also ignores exceptions +whose name starts with ignored.

        Reports fields which may be converted to a local variable. This is so because +in every method where the field is used, it is assigned before it is first read. +Hence, the value that the field had before the method call may not be observed, +so it might as well not be stored in the enclosing object.

        +

        Limitations:

        +
        • We can only check private fields for now.
        • The rule is not aware of threading, so it may cause false positives in concurrent code. Such FPs are best handled by suppression (see also the ignoredAnnotations property).

        Reports assignments to variables that are never used before the variable is overwritten, + or goes out of scope. Unused assignments are those for which + 1. The variable is never read after the assignment, or + 2. The assigned value is always overwritten by other assignments before the next read of + the variable.

        +

        The rule tracks assignements to fields of this, and static fields of the current class. + This may cause some false positives in timing-sensitive concurrent code, which the rule cannot detect.

        +

        The rule may be suppressed with the standard @SuppressWarnings("unused") tag.

        +

        The rule subsumes UnusedLocalVariable, and UnusedFormalParameter. + Those violations are filtered + out by default, in case you already have enabled those rules, but may be enabled with the property + reportUnusedVariables. Variables whose name starts with ignored or unused are filtered out, as + is standard practice for exceptions.

        +

        Limitations:

        +
        • The rule currently cannot know which method calls throw exceptions, or which exceptions they throw. In the body of a try block, every method or constructor call is assumed to throw. This may cause false-negatives.
        • The rule cannot resolve assignments across constructors, when they're called with the special this(...) syntax. This may cause false-negatives.
        +

        Both of those limitations may be partly relaxed in PMD 7.

        Java 10 introduced the var keyword. This reduces the amount of code written because java can infer the type +from the initializer of the variable declaration.

        +

        This is essentially a trade-off: On the one hand, it can make code more readable by eliminating redundant +information. On the other hand, it can make code less readable by eliding useful information. There is no +blanket rule for when var should be used or shouldn't.

        +

        It may make sense to use var when the type is inherently clear upon reading the statement +(ie: assignment to either a literal value or a constructor call). Those use cases +can be enabled through properties.

        +

        Notice that lambda parameters are allowed, as they are already inferred by default (the var keyword +is completely optional).

        When doing String::toLowerCase()/toUpperCase() conversions, use an explicit locale argument to specify the case +transformation rules.

        +

        Using String::toLowerCase() without arguments implicitly uses Locale::getDefault(). +The problem is that the default locale depends on the current JVM setup (and usually on the system in which +it is running). Using the system default may be exactly what you want (e.g. if you are manipulating strings +you got through standard input), but it may as well not be the case (e.g. if you are getting the string over +the network or a file, and the encoding is well-defined and independent of the environment). In the latter case, +using the default locale makes the case transformation brittle, as it may yield unexpected results on a machine +whose locale has other case translation rules. For example, in Turkish, the uppercase form of i is İ (U+0130, +not ASCII) and not I (U+0049) as in English.

        +

        The rule is intended to force developers to think about locales when dealing with strings. By taking a +conscious decision about the choice of locale at the time of writing, you reduce the risk of surprising +behaviour down the line, and communicate your intent to future readers.

        +

        Example

        +

         // violation - implicitly system-dependent conversion

        The use of the '+=' operator for appending strings causes the JVM to create and use an internal StringBuffer. +If a non-trivial number of these concatenations are being used then the explicit use of a StringBuilder or +threadsafe StringBuffer is recommended to avoid this.

        Java 7 introduced the try-with-resources statement. This statement ensures that each resource is closed at the end +of the statement.

        Parenthesized expressions are used to override the default operator precedence + rules. Parentheses whose removal would not change the relative nesting of operators + are unnecessary, because they don't change the semantics of the enclosing expression.

        +

        Some parentheses that strictly speaking are unnecessary, may still be considered useful for readability. This rule allows to ignore violations on two kinds of unnecessary parentheses:

        +
        • "Clarifying" parentheses, which separate operators of difference precedence. While unnecessary, they make precedence rules explicit, which may be useful for rarely used
        +
        • "Balancing" parentheses, which are unnecessary but visually balance out another pair of parentheses around an equality operator. For example, those two expressions are equivalent:
           (a == null) != (b == null)
          +                 a == null != (b == null)
          The parentheses on the right are required, and the parentheses on the left are just more visually pleasing. Unset the property ignoreBalancing to report them.

When the XPath query finds a match, a violation is created.

        +

        Let's take a simple example: assume we have a Factory class that must be always declared final. +We'd like to report a violation each time a declaration of Factory is not declared final. Consider the following class:

        +
        
        +import io.factories.Factory;
        +
        +public class a {
        +  Factory f1;

        +    int a;
        +  }
        +}
        +
        +

        The following expression does the magic we need:

        +
        
        +//(FieldDeclaration|LocalVariableDeclaration)[
        +      not (pmd-java:modifiers() = 'final')

        Enforces the modifier order recommended by the JLS. Apart from sorting modifiers, this rule also enforces that all annotations appear before all modifier keywords. By setting the property typeAnnotations, you can also enforce that type annotations appear right of the modifier keywords, next to the type they apply to. This property can have three values:

        +
        • on type: Type annotations must be placed next to the type they apply to
        • on decl: Type annotations must be placed with other annotations, before modifiers. This is not enforced if the type annotations syntactically appears within the type, e.g.
        • anywhere (default): Either position fits. They still cannot be interspersed within keyword modifiers. Annotations that are not type annotations are still required to be before keyword
