WeakHashMap values Example
WeakHashMap class values example.ublic Collection values() Returns a Collection view of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa.
Here is the code
/**
* @ # Values.java
* A class repersenting use to values method
* of WeakHashMap class in java.util package
* version 22 May 2008
* author Rose India
*/
import java.util.*;
public class Values {
public static void main(String args[]) {
WeakHashMap map = new WeakHashMap();
map.put(1, "A");
map.put(2, "B");
map.put(3, "C");
map.put(4, "D");
System.out.println("map = " + map);
System.out.println("values of the map " + map.values());
}
} |
Output
map = {4=D, 3=C, 2=B, 1=A}
values of the map [D, C, B, A] |
