VectorExample.java

import java.util.Vector;

/*
 *  Example of setElementAt(E obj, int index) method. 
 */
public class VectorExample
{
    public static void main( String[] args )
    {
        Vector<Integer> vector = new Vector<Integer>();

        vector.add(20);
        vector.add(30);
        vector.add(40);
        vector.add(50);

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

        /*
         * Sets the component at the specified index of this vector to be the
         * specified object. The previous component at that position is
         * discarded.
         */

        vector.setElementAt(1000, 1);

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

    }
}

Output

vector  : [20, 30, 40, 50]

vector  : [20, 1000, 40, 50]
