java.util
Enumeration

Declaration
public interface Enumeration
Description
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.
Since: JDK1.0, CLDC 1.0
See Also: nextElement(), Hashtable, Hashtable.elements(), Hashtable.keys(),
Vector, Vector.elements()
