import java.util.ArrayDeque; //导入方法依赖的package包/类
public static void main(String[] args) {
ArrayDeque<Integer> ad = new ArrayDeque<>();
// add element of array
ad.add(3);
ad.add(4);
System.out.println("Add Element. content: " + ad.toString());
// add element to its first (head) & last (tail) index
ad.addFirst(1);
