DequeExample.java
import java.util.Deque;
import java.util.LinkedList;

/*
 *  Example of contains(Object o) method.
 */
public class DequeExample
{

    public static void main(String[] args)
    {
        Deque<Integer> deque = new LinkedList<Integer>();
        deque.add(200);
        deque.add(300);
        deque.add(200);

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

        /*
         * Returns true if this deque contains the specified element.
         */
        boolean isExist = deque.contains(300);
        System.out.println("is 300 Exist :  " + isExist);

        isExist = deque.contains(10000);
        System.out.println("is 10000 Exist : " + isExist);

    }

}




Output
deque : [200, 300, 200]

is 300 Exist :  true
is 10000 Exist : false
