import java.util.LinkedList;
import java.util.Queue;

public class QueueExample
{

    public static void main( String[] args )
    {
        Queue<Integer> queue = new LinkedList<Integer>();
        queue.add(200);
        queue.add(300);
        queue.add(400);
        queue.add(500);

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

        Iterator<Integer> iterator = queue.iterator();
        /*
         * Using Iterator traverse the queue and get each element.
         */
        while( iterator.hasNext() )
        {
            Integer value = iterator.next();
            System.out.println(value);
        }

    }
}

Output
queue : [200, 300, 400, 500]

200
300
400
