Interface Enumeration<E>
- NamingEnumeration<T>
- StringTokenizer
Interface for lists of objects that can be returned in sequence. Successive
objects are obtained by the nextElement method.
As of Java 1.2, the Iterator interface provides the same functionality, but
with shorter method names and a new optional method to remove items from the
list. If writing for 1.2, consider using Iterator instead. Enumerations over
the new collections classes, for use with legacy APIs that require them, can
be obtained by the enumeration method in class Collections.
boolean | hasMoreElements()- Tests whether there are elements remaining in the enumeration.
|
E | nextElement()- Obtain the next element in the enumeration.

that is, if the next call to nextElement will not throw a
NoSuchElementException.
