Cyclic inheritance when implementing inner interface in enum

Question

I have the following implementation that gives a compiler error:

public enum FusionStat implements MonsterStatBuilderHelper {
    ATTACK {
        @Override
         


        

Answer 1

This would be because you are implementing (coding) the interface you are implementing (inheriting) inside of the class that is inheriting from that class.

I wish I could make that sentence better...

But here is a visual example.

Class A implements Interface B {

    Interface B {
    }
}

As far as I know, this is not allowed. You need to define the interface outside of the class (in this case, an Enum).

Like so:

Interface B {
}

Class A implements Interface B {
}

Best practice is probably to break them up into different files.
