Design Pattern Manual Download A design pattern is a set of code design experiences that are repeatedly used, known to most people, classified and cataloged. The purpose of using design patterns is to reuse code, make the code easier to understand by others, and ensure code reliability.

Design patterns are the cornerstone of software engineering, just like the bricks and stones of a building. Reasonable use of design patterns in projects can perfectly solve many problems. Each pattern has corresponding principles in reality to correspond to it. Each pattern describes a problem that keeps recurring around us, and the solution to the problem. Core solution, which is why design patterns can be widely used.
