Java : Collection Framework : Vector (ListIterator)

VectorExample.java
import java.util.ListIterator;
import java.util.Vector;

/*
 *  Example of listIterator() method. 
 */
public class VectorExample
{
    public static void main( String[] args )
    {
        Vector<Integer> vector = new Vector<>();

        vector.add(10);
        vector.add(20);
        vector.add(30);
        vector.add(40);

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

        /*
         * Returns a list iterator over the elements in this list (in proper
         * sequence).
         */

        ListIterator<Integer> listIterator = vector.listIterator();

        System.out.println("Forward direction ---");
        while( listIterator.hasNext() )
        {
            Integer value = listIterator.next();
            System.out.println(value);

        }
        
        System.out.println("\nReverse direction ---");
        while( listIterator.hasPrevious() )
        {
            Integer value = listIterator.previous();
            System.out.println(value);

        }
    }
}

Output
vector  : [10, 20, 30, 40]

Forward direction ---
10
20
30
40

Reverse direction ---
40
30
20
10
