The factory method pattern is used more frequently and is defined as: The factory pattern defines an interface for creating objects, letting subclasses decide which class to instantiate. The factory method defers the instantiation of a

Object-oriented design scheme Product Dog told you today, to do a "simulated duck game", the requirements are as follows: Ducks have common functions, such as swimming and barking. Ducks also have different functions, such as green-headed ducks and

First, let's talk about the inheritance relationship of the specific class of the adapter, as shown in Adapte serves as a bridge between adapterview and view. The adapter loads view (such as the data to be displayed in listview and girdview ). The

Definition Defines an interface used to create objects so that the subclass determines which class to instantiate. The factory method delays the instantiation of a class to its subclass. Generic class diagram In the factory method mode,
