1.31 +/**
1.32 + * An object that implements the Enumeration interface generates a
1.33 + * series of elements, one at a time. Successive calls to the
1.34 + * <code>nextElement</code> method return successive elements of the
1.35 + * series.
1.36 + * <p>
1.37 + * For example, to print all elements of a <tt>Vector<E></tt> <i>v</i>:
1.38 + * <pre>
1.39 + * for (Enumeration<E> e = v.elements(); e.hasMoreElements();)
1.40 + * System.out.println(e.nextElement());</pre>
1.41 + * <p>
1.42 + * Methods are provided to enumerate through the elements of a
1.43 + * vector, the keys of a hashtable, and the values in a hashtable.
1.44 + * Enumerations are also used to specify the input streams to a
1.45 + * <code>SequenceInputStream</code>.
1.46 + * <p>
1.47 + * NOTE: The functionality of this interface is duplicated by the Iterator
1.48 + * interface. In addition, Iterator adds an optional remove operation, and
1.49 + * has shorter method names. New implementations should consider using
1.50 + * Iterator in preference to Enumeration.
1.51 + *
