public interface Enumeration

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());
	}

Vector, Hashtable
