Learn design patterns for fun, say goodbye to bad code, and become a programming "artist"

Learn design patterns for fun, say goodbye to bad code, and become a programming "artist" Resource introduction:

Good programming is both a developer's basic skill and a watershed of ability. In addition to meeting basic functions, how can you make your code concise, efficient and reusable? In addition to continuous iteration, learning design patterns is the best shortcut. Because design patterns are the summary of experience repeatedly used by developers through trial and error, and are also the best solutions to general problems.

However, many people fall into this misunderstanding: design patterns are abstract knowledge that can only be used in interviews; they learn sample codes mechanically but are unable to write them themselves; design patterns are too simple and cannot cope with complex business problems. Only by clearing these obstacles can you truly use design patterns.

What will you learn?

This column has designed the simplest learning path for you, distilled practical programming skills, combined with actual business scenarios, disassembled the principles behind each model, and helped you transform abstract knowledge into practical skills. The column is divided into the following three progressive modules:

Module 1: Programming thinking. This module is an efficient programming methodology extracted from design patterns, such as the combinatorial thinking conveyed by the Unix philosophy to cope with changing needs; the classic layered thinking helps you see through modern architectural design; and the engineering thinking helps you efficiently deliver reliable software products. Build a real programming mindset for you, lay a solid programming foundation, and achieve truly efficient programming.

Module 2: Programming principles. We have selected 10 important and basic programming principles, such as the object-oriented design principle (SOLID), the principle of convention (CoC), etc. They are equivalent to the conventions followed in programming. Why do such principles exist and how can we really play their role? These will be explained from the simplest to the most complex through practical examples, and the core application skills will be summarized in due course, so that you can use them "out of the box" in your work.

Module 3: Programming Mode. This course analyzes in detail how to apply 23 Java design patterns in practice, focusing on some case problems related to actual scenarios, analyzing the reasons and solutions behind the emergence of the patterns. After completing the course, you will have a more intuitive and specific understanding of abstract design patterns and master the corresponding programming skills.
