Is it possible to assign numeric value to an enum in Java?

Question

Is anything like this possible in Java? Can one assign custom numeric values to enum elements in Java?

public enum EXIT_CODE {
    A=104, B=203;
}

If you're looking for a way to group constants in a class, you can use a static inner class:

public class OuterClass {
    public void exit(boolean isTrue){
        if(isTrue){
            System.exit(ExitCode.A);
        }else{
            System.exit(ExitCode.B);
        }
    }
    public static class ExitCode{
        public static final int A = 203;
        public static final int B = 204;
    }   
}
