The object seems to have modified its class. Divide this sentence into two parts by commas. The first part means to encapsulate the state into a separate class and delegate the request to the current state object. When the internal state of the object changes, different behavior changes will be brought about. The second part is from the customer's point of view, the object used has completely different behaviors in different states. The object seems to be instantiated from different classes, but in fact this is the effect of using delegates.
