Java Stack Class Methods

The Stack class in Java represents a last-in-first-out (LIFO) stack of objects. It extends the Vector class with five operations that allow a vector to be treated as a stack. The stack class provides a means to hold a collection of objects and provides basic methods for pushing, popping, and peeking elements.

This guide covers various methods available in the Stack class. Each method is described in simple terms to help beginners understand how to use them. These methods enable standard stack operations like checking if the stack is empty, viewing the top element without removing it, removing the top element, and searching for an element within the stack.
