LinkedListExample.java
import java.util.Iterator;
import java.util.LinkedList;

/*
 * Example of descendingIterator() method
 */
public class LinkedListExample
{

    public static void main(String[] args)
    {
        LinkedList<Integer> linkedList = new LinkedList<Integer>();
        linkedList.add(200);
        linkedList.add(300);
        linkedList.add(10000);
        linkedList.add(5000);
        linkedList.add(2000);

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

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

        Iterator<Integer> iterator = linkedList.descendingIterator();

        System.out.println("Reverse Direction -- ");

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

    }

}

Output
linkedList : [200, 300, 10000, 5000, 2000]

Reverse Direction -- 
2000
5000
10000
300
200
