Implementing a Simple LIFO Stack in Java using LinkedList

Last In First Out (LIFO) stacks can be easily implemented in Java using a singly linked list. This example shows a very simple implementation of the stack operations using singly linked list.

 * This class shows a simple implementation of Stack using LinkedList
import java.util.LinkedList;

public class StackUsingLinkedList {

	private LinkedList<Object> list = new LinkedList<Object>();

	public void push(Object item) {
		System.out.println("Stacked: " + item);

	public Object pop() {
		System.out.println("Destacked: " + list.getFirst());
		return list.removeFirst();

	public Object peek() {
		return list.getFirst();

	public int size() {
		return list.size();

	public boolean isEmpty() {
		return list.isEmpty();
	 * Testing the stack. The added objects should be returned in reverse order
	public static void main (String args[]) {
		StackUsingLinkedList stack = new StackUsingLinkedList();
		while (!stack.isEmpty()) {

Here is the output of this program:

Stacked: One
Stacked: Two
Stacked: Three

Destacked: Three
Destacked: Two
Destacked: One
