Class Overview
An object that implements the Enumeration interface generates a series of
elements, one at a time. Successive calls to the nextElement
method return successive elements of the series.
For example, to print all elements of a vector v:
for (Enumeration e = v.elements() ; e.hasMoreElements() ;) {
System.out.println(e.nextElement());
}
Methods are provided to enumerate through the elements of a vector, the keys of a hashtable, and the values in a hashtable.
