Following example shows how to implement stack by creating user defined push method for entering elements and pop method for retrieving elements from the stack. The Stack class represents a last-in-first-out LIFO stack of objects. An abstract class is one which informs what to do along it has implementation of normal method that can be used by its child classes.
As a Vector implements List Stack class is also the List implementation class but does NOT support all the operations of Vector or List. This method adds an element at the top of the stack. Animalspop - remove element from the top of the stack.
