        Deque<Integer> deque = new LinkedList<Integer>();
        deque.add(2000);
        deque.add(5000);
        deque.add(10000);

        System.out.println("deque : " + deque + "\n");

        /*
         * Returns the number of elements in this deque.
         */
        int size = deque.size();
        System.out.println("size : " + size);
