Interface Enumeration

public interface netscape.util.Enumeration
{
    /* Methods
     */
    public abstract boolean hasMoreElements();
    public abstract Object nextElement();
}
The Enumeration interface specifies an API enabling iteration through a set of elements. The following code demonstrates how to print all the values of a Hashtable using an Enumeration:
    Enumeration enumeration;
    Object key;
    enumeration = table.keys();
    while (enumeration.hasMoreElements()) {
        key = enumeration.nextElement();
        System.out.println("key = " + key + ", value = " + table.get(key);
    }
