What is the Factory design pattern in Java?
Article Introduction：The factory design pattern is used to create objects without specifying specific classes. The factory method determines which class to instantiate based on input. For example, DocumentFactory returns PdfDocument or WordDocument instances according to the document type, thereby realizing the decoupling of client code from specific implementations, so that when adding new document types, you only need to expand the factory method without modifying client code. This pattern is suitable for scenarios where object types are determined at runtime, need to centrally create logic or system needs to support flexible expansion, and ultimately improve the maintainability, scalability and loose coupling of the code.

Factory design pattern in Java example
Article Introduction：The factory pattern is to encapsulate object creation logic through a factory class, so that the caller does not need to care about the specific implementation class. 1. Define the unified behavior specification of interface Shape; 2. Create Circle and Rectangle implementation classes; 3. Write ShapeFactory factory class to return different instances according to parameters; 4. Use the factory class to obtain objects and call methods. This mode is suitable for scenarios where object creation is complex, the type is often changed, or the principle of opening and closing is required. It can effectively decouple the caller and specific classes and reduce maintenance costs.

Can you explain the Factory design pattern with a simple example in Java?
Article Introduction：The factory design pattern creates objects centrally through a factory class, avoiding the client using new hard code to instantiate specific classes; 2. Define the abstract product Pizza, and the specific products CheesePizza, VeggiePizza and PepperoniPizza inherit it; 3. PizzaFactory returns the corresponding Pizza instance according to the input type; 4. The client creates objects through the factory and calls its methods to realize the encapsulation of loose coupling and creation logic, which is convenient for expansion and maintenance. This implementation is a simple factory model, ending with a complete sentence.

Simple Factory
Article Introduction：What is Simple Factory?
Simple factory is not design pattern. It simply decouples object creation from client code. In other words, Simple factory encapsulates object instantiation by moving instantiation logic to a separate class.

Factory Method Pattern in Python
Article Introduction：The factory method pattern is a design pattern that instantiates specific classes through subclass decisions. It defines an interface to create objects, delaying the creation of objects to subclass processing, thereby achieving decoupling. This mode is suitable for scenarios such as hidden object creation details, uncertain future subclass types, and the need to call different objects in a unified interface. The implementation steps include: defining the base class or interface; creating multiple subclasses; writing factory functions or methods that return different instances according to parameters. Factory methods can be further encapsulated into classes to facilitate management of complex logic. When using it, you should pay attention to avoiding too many conditional judgments, preventing business logic from being mixed into the factory, avoiding over-design. It is also recommended to deal with abnormal inputs, keep the logic simple, and use it only when scalability is required.

What is the difference between a Factory, an Abstract Factory, and a Builder design pattern?
Article Introduction：FactoryMethod is used to decide the instantiation of specific subclasses at runtime, suitable for different variant creation of a single product type; 2. AbstractFactory is used to create a family of related or dependent objects to ensure compatibility between products, suitable for cross-platform or theme systems; 3. Builder is used to construct complex objects in step by step, especially when the object has multiple optional configurations or needs to avoid telescoping constructors, which is suitable for scenarios where the construction process is complex and needs to be set clearly.
