WalkthroughA new Kotlin file, Changes
Poem
Impact AnalysisIntroduction of new public Kotlin entities with multiple syntactic and semantic errorsA new Kotlin source file introduces several public classes, functions, and interfaces, but the code contains numerous syntactic and semantic errors that will prevent successful compilation and usage. Users or API consumers attempting to use these entities will encounter build failures and runtime issues, making the new functionality inaccessible or unreliable. Attempt to compile and run the code to verify that all public APIs are accessible and function as intended. Test error handling, edge cases, and ensure that all declared entities behave correctly and do not introduce regressions or runtime failures. 🔍 Related Files

Handle division by zero.
Calling divide(10, 0) will cause an ArithmeticException at runtime.
Either change the divisor to a non-zero value or add error handling in the divide function.
🤖 Prompt for AI Agents
In test.kt at line 14, the code calls divide(10, 0), which causes a division by
zero error at runtime. To fix this, either change the divisor from 0 to a
non-zero value or modify the divide function to handle division by zero by
checking if the divisor is zero and returning an appropriate result or throwing
a controlled exception.

In test.kt around lines 60 to 65, the function mismatchedBraces is missing its
closing brace. Add a closing curly brace at the end of the function to properly
close it and fix the syntax error.

Add missing parentheses in function declaration.
When overriding a function, parentheses are required even if there are no parameters.

In test.kt at line 34, the overridden function declaration is missing
parentheses. Add empty parentheses after the function name 'work' to correctly
declare it as a function, even if it takes no parameters.

In test.kt around lines 41 to 43, the function missingReturn is declared to
return a String but currently lacks a return statement. Fix this by adding a
return statement that returns a String value, for example, convert the
StringBuilder s to a String and return it at the end of the function.

In test.kt at line 11, there is a type mismatch because a String literal "Hello"
is being assigned to a variable declared as Int. To fix this, either change the
variable type from Int to String or assign an integer value to the variable.
Ensure the variable type matches the assigned value type.

In test.kt around lines 52 to 58, the when expression is used incorrectly
without returning a value, but the function badWhen is declared to return a
String. Fix this by making the when expression an expression that returns a
String value directly, either by adding an equals sign before when or by
returning the when expression result explicitly.

iteration variable and the list.

In test.kt at line 50, the variable 'uninitialized' is declared as a
non-nullable Double without initialization, which is not allowed. Fix this by
either initializing 'uninitialized' with a default Double value at declaration
or by making the variable nullable by adding a '?' after the type to allow it to
hold null.
