add values to enums or change string

[rugae]

I was wondering if it's possible to change or add values to enum types? Such as changing the string "This is a msg" or add additional value to the type test.
May I have some tips?

public enum Test {
        VALUE("This is a msg");
                
        private String x;
        
        Test (String y) {
            setX(y);
        }
        public void setX(String y) {
            x = y;
        }            
        public String getX(){        
            return x;
        }
    }

I don't think you can add enum values. By definition, enum values are constant:

So when should you use enums? Any time you need a fixed set of constants.

From http://java.sun.com/j2se/1.5.0/docs/guide/language/enums.html

Have a look at that page, it could help.
