Actually the stack class does not inherit linked list class. If inheritence exists then insertbefore() , insertafter(), insertstposition(), deletenode().... these functions will be available in the stack class which is not desirable. And Here the relation between stack and linked list is a "has a" relation not a "is a" ralation...

The StackLinkedList class inherits the LinkedList class because the StackLinkedList class uses attributes and member functions of the LinkedList class
