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 input streams to a + * SequenceInputStream. + *

+ * NOTE: The functionality of this interface is duplicated by the Iterator + * interface. In addition, Iterator adds an optional remove operation, and + * has shorter method names. New implementations should consider using + * Iterator in preference to Enumeration. + * + * @see java.util.Iterator + * @see java.io.SequenceInputStream + * @see java.util.Enumeration#nextElement() + * @see java.util.Hashtable + * @see java.util.Hashtable#elements() + * @see java.util.Hashtable#keys() + * @see java.util.Vector + * @see java.util.Vector#elements() + * + * @author Lee Boynton + * @since JDK1.0 + */ +public interface Enumeration { + /** + * Tests if this enumeration contains more elements. + * + * @return true if and only if this enumeration object + * contains at least one more element to provide; + * false otherwise. + */ + boolean hasMoreElements(); + + /** + * Returns the next element of this enumeration if this enumeration + * object has at least one more element to provide. + * + * @return the next element of this enumeration. + * @exception NoSuchElementException if no more elements exist. + */ + E nextElement(); +}
