Deque<Integer> deque = new ArrayDeque<Integer>(8);
// use add() method to add elements in the deque
deque.add(10);
deque.add(20);
deque.add(30);
// print all the elements available in deque
for (Integer n : deque) {
System.out.println("Number = " + n);
}
// Let clear all the elements in the deque
deque.clear();
