+# About Repository
+This repository contains the *Enum class* in Java, with examples. Enum is short for "enumerations", which means "specifically listed".<br><br>
+An enum is a special "class" that represents a group of constants (unchangeable variables, like final variables). To create an enum, use the enum keyword (instead of class or interface), and separate the constants with a comma. *Note* that they should be in uppercase letters.
+
+## About files
+1. [Day.java][1] : Contains the enum class used in all other files (test class).
+1. [inBuiltFunc.java][6] : Showcases built-in Enum methods in Java.
+1. [dotSyntax.java][2] : Access enum constants with the dot syntax.
+1. [enumInsideClass.java][3] : Having enum inside another class.
+1. [enumLoop.java][4] : Returning an array of all enum constants using value() method of enum type.This method is useful when you want to loop through the constants of an enum.
+1. [switchCase.java][5] : Using enum in switch case statement.
