Example 1

  import java.util.concurrent.ConcurrentLinkedQueue;  public class ConcurrentLinkedQueueRemoveExample1 {      public static void main(String[] args) {         ConcurrentLinkedQueue<Integer> queue = new ConcurrentLinkedQueue<Integer>();         queue.add(12);         queue.add(98);         queue.add(122);         queue.add(102);         queue.add(112);         System.out.println(“Elements in queue : “+queue);         //remove() method will remove the specified element from the queue         queue.remove(122);         queue.remove(102);         System.out.println(“Remaining elements in queue : “+queue);      }  }
