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")
