Factory Method is a creational design pattern that provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created.

Prototype is a creational design pattern that lets you copy existing objects without making your code dependent on their classes.

Builder is a creational design pattern that lets you construct complex objects step by step. The pattern allows you to produce different types and representations of an object using the same construction code.

Abstract Factory is a creational design pattern that lets you produce families of related objects without specifying their concrete classes.

Summary
This article mainly introduces software design patterns. It explains the concept of design patterns as typical solutions to common software design problems, rather than specific code, and distinguishes them from algorithms. The article elaborates on the components of design patterns, such as intent, motivation, structure, and code examples, and provides a catalog of various design patterns and refactoring techniques, covering creational, structural, and behavioral patterns. Finally, the article includes contact information.

DI frameworks, conversely, address these issues by enabling mock object injection for testing, dynamic configuration, loose coupling through interfaces, and simplified multithreading and resource management. This ultimately results in more flexible, testable, and maintainable systems.
