What will be the output of the following Java code?

import java.util.*;
class vector 
{
    public static void main(String args[]) 
    {
        Vector obj = new Vector(4,2);
        obj.addElement(new Integer(3));
        obj.addElement(new Integer(2));
        obj.addElement(new Integer(6));
        obj.insertElementAt(new Integer(8), 2);
        System.out.println(obj);
    }
}
