Illustration of implementation of inheritance

Let us take the illustration of implementation of inheritance. Suppose that we are about to implement the Stack class and by now we have a List class available. You can be tempted to create Stack inherit from List. Pushing an element onto stack can be achieved by adding an element to end of list and popping an element from a stack corresponds to removing an element from end of the list. But, you are also inheriting unwanted list operations which add or remove elements from arbitrary positions in list.
