Usage

From source file:Main.java

public static void main(String args[]) throws Exception {
    Vector<String> v = new Vector<String>();
    v.add("a");/*w w w  .j  ava2s . c  om*/
    v.add("b");
    v.add("java2s.com");

    Collection<String> col = v;
    Enumeration<String> e = Collections.enumeration(col);

    for (; e.hasMoreElements();) {
        Object o = e.nextElement();
        System.out.println(o);
    }
}

From source file:Main.java

public static void main(String args[]) throws Exception {
    Vector<String> v = new Vector<String>();
    v.add("a");/*  w  ww  . j av a  2s .c om*/
    v.add("b");
    v.add("c");

    Collection<String> col = v;
    Enumeration<String> e = Collections.enumeration(col);

    for (; e.hasMoreElements();) {
        Object o = e.nextElement();
