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.
