Removing second element from Queue in Java:

import java.util.*; public class Qlist { public static void main(String[] args) throws IllegalStateException { // create object of Queue Queue<Integer> Q = new LinkedList<Integer>(); // Add numbers to end of Queue Q.add(7855642); Q.add(35658786); Q.add(5278367); Q.add(74381793); System.out.println("Queue before removing second element:"); // print queue System.out.println("Queue: " + Q); // print head and deletes the head Q.remove(35658786); System.out.println("Queue after removing second element:"); System.out.println("Queue: " + Q); } }
