hashCode() and equals() in Collections

Input the map size for the case below.

Note that it doesn't matter if hashCode() or equals() are overridden or not. You will get the same result.

    Person james = new Person("James Gosling");
    Person person = james;

    Map<Person, Integer> map = new HashMap();
    map.put(james, 1995);
    map.put(person, 1995);
        
    System.out.println(map.size());
