public class CollectionsExample
{

    public static void main(String[] args)
    {

        Vector<Integer> vector = new Vector<Integer>();

        vector.add(2000);
        vector.add(3000);
        vector.add(4000);
        vector.add(5000);
        vector.add(6000);

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

        /*
         * Returns an enumeration of the components of this vector
         */
        Enumeration<Integer> enumeration = vector.elements();

        /*
         * Returns an array list containing the elements returned by the
         * specified enumeration in the order they are returned by the
         * enumeration.
         */
        ArrayList<Integer> arrayList = Collections.list(enumeration);

        System.out.println("arrayList : " + arrayList);

    }

}
Output
vector : [2000, 3000, 4000, 5000, 6000]

arrayList : [2000, 3000, 4000, 5000, 6000]
