Well  in java  you can also create a parameterized enum  Say you want to create a className enum  in which you need to store classCode as well as className  you can do that like this   public enum ClassEnum        ONE 1   One         TWO 2   Two        THREE 3   Three        FOUR 4   Four        FIVE 5   Five              private int code      private String name       private ClassEnum int code  String name            this code   code          this name   name             public int getCode             return code             public String getName             return name

public enum MyEnum      ONE 1      TWO 2      private int value     private MyEnum int value          this value   value          public int getValue           return value           In short - you can define any number of parameters for the enum as long as you provide constructor arguments  and set the values to the respective fields   As Scott noted - the official enum documentation gives you the answer  Always start from the official documentation of language features and constructs   Update  For strings the only difference is that your constructor argument is String  and you declare enums with TEST  test

enums are classes in Java  They have an implicit ordinal value  starting at 0  If you want to store an additional field  then you do it like for any other class   public enum MyEnum        ONE 1       TWO 2        private final int value       private MyEnum int value            this value   value             public int getValue             return this value
