Question

The code shown below does work because the method values() is static. My question is how can I achieve what the code below would do if B was not generic.

class A<B extends Enum<B>> {
    public A() {
        for (B b : b.values()) {

        }
    }
}

I can think of two solutions:

1. pass the enum values into A’s constructor
2. make B implement an interface that defines a method for obtaining the enum values.

Both seem messy to me. Anyone have any better solutions?

Answer 1

Try using getEnumConstants()
