import java.util.IdentityHashMap;

import java.util.Map;
/*来自 N o w  J a v a  . c o m*/

public class Main {

  public static void main(String[] args) throws Exception {

    Map objMap = new IdentityHashMap();


    // Add the object and value pair to the map

    Object o1 = new Integer(123);

    Object o2 = new Integer(123);

    objMap.put(o1, "first");

    objMap.put(o2, "second");
