Stack Class in Java Tutorial

Java Stack is the legacy Collection class. It extends the Vector class with five operations to support the LIFO(Last In First Out) operations. It is available in the Collection API since Java 1.0. As a Vector implements List, Stack class is also the List implementation class but does NOT support all the operations of Vector or List. As Stack supports LIFO, it is also known as LIFO Lists. Java is an  Object-Oriented programming language as well all know.
