IdentityHashMap clone Example
IdentityHashMap class clone example. This example shows you how to use clone method.
IdentityHashMap class clone example.public Object clone() Returns a shallow copy of this identity hash map: the keys and values themselves are not cloned.
Here is the code
/**
* @ # Clone.java
* A class repersenting use to clone method
* of IdentityHashMap class in java.util package
* version 26 May 2008
* author Rose India
*/
import java.util.*;
public class Clone {
public static void main(String args[]) {
IdentityHashMap map = new IdentityHashMap();
//Add the mapping into the map
map.put(1, "A");
map.put(2, "A");
map.put(3, "B");
System.out.println("Map " + map);
//Create clone
IdentityHashMap map1 = (IdentityHashMap) map.clone();
System.out.println("Map1 " + map1);
}
} |
Output
Map {2=A, 1=A, 3=B}
Map1 {2=A, 1=A, 3=B} |
