public static void main(String[] args) {
// Creating an ArrayDeque with initial capacity of
// storing elements
Deque < String > d_queue = new ArrayDeque < String > (10);
// By using add() method to add elements
// in ArrayDeque
d_queue.add("C");
d_queue.add("C++");
d_queue.add("Java");
d_queue.add("Php");
