Problem with ENUM in eclipse

Question

I have the the following error in my eclipse IDE:

Cannot reference a field before it is defined

I try to use an enum variable and some of its values have the same name.

public enum Enun {
    A(STATIK);
    private static int STATIK = 1;

    private Enun(final int i) {
    }
}

Could anyone tell me how I can solve this problem please?

Thanks :)

Answer 1

Yeah, you can't reference static members of the enum in the enum declaration. If you want to name these numbers, then you should make the STATIK a member of a nested static class:

A(Constants.STATIK);

private static class Constants {
    private static int STATIK = 1;
}

private Enun(final int i) {
}

Although I would question the need for this - the enum name should tell you all you need to know about those numbers, and you shouldn't need an aditional static declaration.

Answer 2

You can't extend anything else because enum extends something already (by specification) but you CAN implement with an enum! Try this

public interface EnunConstants {
    int STATIK = 1;
    int AWESOME = 2;
    int POSSUM = 3;

}

public enum Enum implements EnunConstants {
    A(STATIK),
    B(AWESOME),
    C(POSSUM);

    private int val;

    private Enun(final int i) { this.val = i; }
    public int getVal() { return val; }

}

public class Sergio {

    public static void main(String[] args) {
        Enun S = Enun.A;
        System.out.println(S.getVal());
        Enun P = Enun.C;
        System.out.println(P.getVal());

    }

}
