Interface Enumeration

public interface Enumeration

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.

Method Summary

boolean	hasMoreElements() Tests if this enumeration contains more elements.
Object	nextElement() Returns the next element of this enumeration if this enumeration object has at least one more element to provide.
