Interface java.util.Enumeration
- public interface Enumeration
- extends Object
The Enumeration interface specifies a set of methods that may be used
to enumerate, or count through, a set of values. The enumeration is
consumed by use; its values may only be counted once.
For example, to print all elements of a Vector v:
for (Enumeration e = v.elements() ; e.hasMoreElements() ;) {
System.out.println(e.nextElement());
}
- See Also:
- Vector, Hashtable
-
hasMoreElements()
- Returns true if the enumeration contains more elements; false
if its empty.
-
nextElement()
- Returns the next element of the enumeration.
hasMoreElements
public abstract boolean hasMoreElements()
- Returns true if the enumeration contains more elements; false
if its empty.
nextElement
public abstract Object nextElement()
- Returns the next element of the enumeration. Calls to this
method will enumerate successive elements.
- Throws: NoSuchElementException
- If no more elements exist.
