Returns an enumeration of the values in this hashtable.

Usage

From source file:MainClass.java

public static void main(String[] s) {
    Hashtable table = new Hashtable();
    table.put("key1", "value1");
    table.put("key2", "value2");
    table.put("key3", "value3");

    Enumeration e = table.elements();
    while (e.hasMoreElements()) {
        String key = (String) e.nextElement();
        System.out.println(key + " : " + table.get(key));
    }//from   ww w . jav a  2s.  c om

    System.out.println(table.values());
}
