20 . Set<T>
The Set<T> interface is in the java.util package.
The Set<T> interface extends the Collection<T> interface and has all the same method headings. However, the
semantics of the add methods vary as described below.
public boolean add(T element) (Optional)
If element is not already in the calling object, element is added to the calling object and true is returned. If element is in the
calling object, the calling object is unchanged and false is returned.
public boolean addAll(Collection<? extends T> collectionToAdd) (Optional)
Ensures that the calling object contains all the elements in collectionToAdd. Returns true if the calling object changed
as a result of the call; returns false otherwise. Thus, if collectionToAdd is a Set<T>, then the calling object is changed
to the union of itself with collectionToAdd.

21 .The List<T> interface has more method headings than the Collection<T> interface.
