an algorithm uses data that clients shouldn't know about. Use the Strategy pattern to avoid exposing complex, algorithm-specific data structures. a class defines many behaviors, and these appear as multiple conditional statements in its operations. Instead of many conditionals, move related conditional...
永不磨灭的设计模式 - ShuSheng007blog.shusheng007.top/archives/design-pattern 前言 人在IT江湖飘,不懂设计模式咋装X? 我们这个社会上的事情大概率都符合八二法则,软件领域也一样。例如你学习一门编程语言,工作中常用的类来来回回也就那么几十个。那么多设计模式,最常被人使用的也就那么几种,所以我们在...

The Strategy pattern is a behavioral design pattern that allows you to define a family of algorithms, encapsulate each one as a separate class, and make them interchangeable. It enables clients to choose from different algorithms at runtime without tightly coupling the client code to specific imple...
