extends Object
The Enumeration interface specifies a set of methods that may be used
to enumerate, or count through, a set of values. The enumeration is
consumed by use; its values may only be counted once.
For example, to print all elements of a Vector v:
for (Enumeration e = v.elements() ; e.hasMoreElements() ;) {
System.out.println(e.nextElement());
}
