Chapter I. INTRODUCTION1. What is design mode?Design patterns are the core solutions that people use to solve similar problems and solve such problems. Design patterns are used to implement design reuse.2. Four

1. four essential elements of a pattern:(1) pattern name;(2) problem;(3) solution;(4) consequences: the results and trade-offs of applying the pattern. 2. One person's pattern can be another person's primitive building block. 3. The design patterns in this book are descriptions of communicating objects and classes th

I started to learn the design model and posted "design patterns can reuse the basis of object-oriented software" on the Internet. After reading the introduction, I found that I have written so many self-satisfied code before, however, from the perspective of the

, including experienced, senior programmers. I also suggest that learning design patterns should begin with this book. Not only does it explain the concept in a clear way, it also gives a lot of diagrams, exercises, tests, and living examples to help you think and absorb. I'm a huge fan of head first series because head first Java and head first
