Question

I have two Enums as follows:

enum Connector {
    AND, OR, XOR;
}

enum Component {
    ACTIVITY
}

Now, I have a variable named follower in a class Event. This variable (follower) can have (and should have) value from either of the above two Enums.

So, What datatype should I give to the follower variable?

Answer 1

private Enum follower;

And you can make both enums implement the same interface, for example Follower, and let the field be:

private Enum<? extends Follower> follower;

But you’d better redesign the whole thing, it doesn’t feel right this way.
