Suppose I have a base class named Visitor, and it has 2 subclass Subscriber and NonSubscriber.

At first a visitor is start off from a NonSubscriber, i.e.

NonSubscriber mary = new NonSubscriber();

Then later on this "mary" subscribed to some services, and I want to change the type of "mary" to Subscriber.

What is the conventional way to do that?
