How can I declare enums using java

Question

I want to convert this sample C# code into a java code:

public enum myEnum {   ONE = "one",   TWO = "two", };  

Because I want to change this constant class into enum

public final class TestConstants {     public static String ONE = "one";     public static String TWO= "two"; } 

Answer 1

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")

Answer 2

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;     } }
