Something like 'contains any' for Java set?

Question

I have two sets, A and B, of the same type.

I have to find if A contains any element from the set B.

What would be the best way to do that without iterating over the sets? The Set library has contains(object) and containsAll(collection), but not containsAny(collection).

Answer 1

Wouldn't Collections.disjoint(A, B) picture? From the documentation:

Returns true if the two specified collections have no elements in common.

Thus, the process returns false if the groups contain any basic elements.
