VectorExample.java
import java.util.Vector;

/*
 *  Example of elementAt(int index),get(int index) methods. 
 */
public class VectorExample
{

    public static void main( String[] args )
    {
        Vector<Integer> vector = new Vector<Integer>();

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

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

        /*
         * Returns the component at the specified index.
         * 
         * This method is identical in functionality to the get(int) method
         * (which is part of the List interface).
         */

        Integer value = vector.elementAt(1);

        System.out.println("elementAt method : value : " + value);

        /*
         * Returns the element at the specified position in this Vector.
         */
        value = vector.get(1);

        System.out.println("get method : value : " + value);

    }
}

Output
vector  : [10, 20, 30]

elementAt method : value : 20
get method : value : 20
