Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    IdentityHashMap<Object, Object> objMap = new IdentityHashMap<Object, Object>(5);

    Object o1 = new Integer(123);
    Object o2 = new Integer(123);
    objMap.put(o1, "first");
    objMap.put(o2, "second");

    Object v1 = objMap.get(o1); // first
    Object v2 = objMap.get(o2); // second
}

From source file:Main.java

public static void main(String[] args) {
    Map<Employee, String> map2 = new HashMap<Employee, String>();
    Employee e2 = new Employee("J", 26);
    map2.put(e2, "MGMT");
    System.out.println(map2);//from  w w  w  .  ja v  a 2s .  co m
    e2.setAge(27);
    System.out.println(map2);
    System.out.println(map2.containsKey(e2));//false

    IdentityHashMap<Employee, String> map1 = new IdentityHashMap<Employee, String>(map2);

    System.out.println(map1);
}
