Name
Map.Entry<K,V>
Synopsis
This
interface represents a single mapping, or association, between a key
object and a value object in a Map
. Like
Map
itself, Map.Entry
has been
made generic in Java 5.0 and defines the same type variables that
Map
does.
The entrySet( )
method of a Map
returns a Set
of Map.Entry
objects that represent the set of mappings in the map. Use the
iterator( )
method of that Set
to enumerate these Map.Entry
objects. Use
getKey( )
and getValue( )
to
obtain the key and value objects for the entry. Use the optionally
supported setValue( )
method to change the value
of an entry. This method throws a
java.lang.UnsupportedOperationException
if it is
not supported by the implementation.
public interface Map.Entry<K,V> { // Public Instance Methods boolean equals(Object o); K getKey( ); V getValue( ); int hashCode( ); V setValue(V value); }
