import java.util.*;

public class IdentityHashMapDemo {
   public static void main(String args[]) {
      // create identity hash map
      IdentityHashMap ihmap = new IdentityHashMap();
      
      // populate the map
      ihmap.put(1, "java");
      ihmap.put(2, "util");
      ihmap.put(3, "package");
      
      // create entry set from the map
      Set enset=ihmap.entrySet();

      System.out.println("Set view of the map: " + enset);
   }    
}

Let us compile and run the above program, this will produce the following result.

Set view of the map: [1=java, 3=package, 2=util]
