Returns the intersection of two sets. It calls Set.retainAll(java.util.Collection) but returns a new set containing the elements of the intersection.

Parameters:

set1 - the first set (can be null, interpreted as empty)

set2 - the second set (can be null, interpreted as empty)

Returns:

the intersection of the sets
