package q_sample;

import java.util.LinkedList;

import java.util.NoSuchElementException;

import java.util.Queue;

public class q_sample {

public static void main(String[] args) {

Queue myQueue = new LinkedList();

myQueue.offer("Monday");

myQueue.offer("Thusday");

boolean flag = myQueue.offer("Wednesday");

System.out.println("Wednesday inserted successfully? "+flag);

try {

myQueue.add("Thursday");

myQueue.add("Friday");

myQueue.add("Weekend");

} catch (IllegalStateException e) {

e.printStackTrace();

}

System.out.println("Pick the head of the queue: " + myQueue.peek());

String head = null;

try {

head = (String) myQueue.remove();

System.out.print("1) Push out " + head + " from the queue ");

System.out.println("and the new head is now: "+myQueue.element());

} catch (NoSuchElementException e) {

e.printStackTrace();

}

head = (String) myQueue.poll();

System.out.print("2) Push out " + head + " from the queue");

System.out.println("and the new head is now: "+myQueue.peek());

System.out.println("Does the queue contain 'Weekend'? " + myQueue.contains("Weekend"));

System.out.println("Does the queue contain 'Monday'? " + myQueue.contains("Monday"));

}
