Create a generic CheckedSet class representing a set. Add a HashSet datamember to it which is initialized by a parameterless constructor. Add a method for getting the current size of the set. Add an add(T element) method that may throw an AlreadyContainedException checked exception. Create such a user-defined exception class that is thrown when the set already contains the given element; otherwise add the element to the set. Add a contains(T element) method returning a boolean that checks if the set contains the given element. Test the new class in a main program.
