Get the intersection of set1 and set2, set1 becomes the intersection of set1 and set2

**import** java.util.HashSet;
**import** java.util.Set;
**public** **class** Main {
**public** **static** **void** main(String[] argv) **throws** Exception {
Set set1 = **new** HashSet();
Set set2 = **new** HashSet();
set1.retainAll(set2);
// Remove all elements from a set
set1.clear();
}
}
