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

/*
 *  Example of iterator() method.
 */
public class DequeExample
{

    public static void main(String[] args)
    {
        Deque<Integer> deque = new LinkedList<Integer>();
        deque.add(100);
        deque.add(200);
        deque.add(300);

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

        /*
         * Returns an iterator over the elements in this deque in proper
         * sequence. The elements will be returned in order from first (head) to
         * last (tail).
         */

        Iterator<Integer> iterator = deque.iterator();

        while (iterator.hasNext())
        {
            Integer value = iterator.next();
            System.out.println(value);
        }

    }
}

Output
deque : [100, 200, 300]

100
200
300
