public interface Enumeration<E>
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<E>
v:
for (Enumeration<E> 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. Enumerations are also used to specify the i
