WeakHashMap entrySet Example
WeakHashMap class entrySet example. This example shows you how to use entrySet method.
WeakHashMap class entrySet example.public Set entrySet() Returns a Set view of the mappings contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa.
Here is the code
/**
* @ # EntrySet.java
* A class repersenting use to entrySet method
* of WeakHashMap class in java.util package
* version 19 May 2008
* author Rose India
*/
import java.util.*;
public class EntrySet {
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);
//Returns a Set view of the mappings contained in this map.
Set set=map.entrySet();
System.out.println("set = " + set);
}
} |
Output
map = {4=D, 3=C, 2=B, 1=A}
set = [4=D, 3=C, 2=B, 1=A] |
