SUMMARY: INNER | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
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.
