public class Main {
  public static void main(String[] args) {

    Deque<Integer> deque = new ArrayDeque<Integer>(8);

    
    deque.add(25);
    deque.add(2);
    deque.add(1);
    deque.add(40);

    System.out.println(deque);

    // deque contains element 2, returns true
    boolean retval = deque.remove(2);
    if (retval == true) {
      System.out.println("element 2 is removed from the deque");
    } else {
      System.out.println("element 2 is not contained in the deque");
