 */

    public static void main(String[] args)

        vector.add(40);

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

        /*
         * Returns an enumeration of the components of this vector. The returned
         * Enumeration object will generate all items in this vector. The first
         * item generated is the item at index 0, then the item at index 1, and
         * so on.
         */

        Enumeration<Integer> enumeration = vector.elements();

        /*
         * Tests if this enumeration contains more elements.
         */
        while (enumeration.hasMoreElements())
        {
            /*
             * Returns the next element of this enumeration if this enumeration
             * object has at least one more element to provide.
             */
            Integer value = enumeration.nextElement();
            System.out.println(value);

        }

    }
}

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

10
20
30
40
