Gof23 - abstract factory pattern

Let's talk about this Abstract factory pattern ！

Last article （ Click to see ）：GoF23— Factory mode

---

review （ Three models ) ：

Simple factory model (Simple Factory)

Used to produce any product in a unified hierarchical structure （ For adding new products , need Modify the original code , Although the amount of code is small , Poor maintenance ！）
Although it does not conform to the design principles to some extent , But actually Most used ！
Factory method model (Factory Method)

Used to produce fixed products in the same hierarchy （ Support to add any product , Large amount of code , But the maintainability is good ！）
Horizontal scaling , Does not affect operation ！
Abstract factory pattern (Abstract Factory)

Around a Super factory Create other factories . This super factory is also called other The factory of the factory .
Do not add products , Product families can be added , It is very difficult to expand new products ！

Abstract factory pattern ：

package factory.abstract1;
// Mobile phone product interface 
public interface PhoneProduct {
    
    void start();
    void music();
    void code();
    void shutdown();
}
