      • difference

        public static <T> java.util.Set<T> difference​(Set<T> s1,
                                              Set<T> s2)
        Calculates the difference between the given two sets, i.e., the elements of s1 that are not in s2.
        Type Parameters:
        T - the element type

        s1 - the first set
        s2 - the second set
        Returns:
        the set difference
