Can I set enum start value in Java?

Question

I use the enum to make a few constants:

enum ids {OPEN, CLOSE};

the OPEN value is zero, but I want it as 100. Is it possible?

I think you're confused from looking at C++ enumerators. Java enumerators are different.

This would be the code if you are used to C/C++ enums:

public class TestEnum {
enum ids {
    OPEN,
    CLOSE,
    OTHER;

    public final int value = 100 + ordinal();
};

public static void main(String arg[]) {
    System.out.println("OPEN:  " + ids.OPEN.value);
    System.out.println("CLOSE: " + ids.CLOSE.value);
    System.out.println("OTHER: " + ids.OTHER.value);
}
};
