Iterator Pattern Iterator ModeScenario ConjectureIf you write code frequently, you will encounter traversing an array. Use the for loop to obtain the array subscript and perform further operations. For example, the following code:Int [] array = new int [5];For (int I = 0; I System. out. println ("" + I );}Or:Int [] array = new int [5];For (int I: array ){System. out. println ("" + I );}Of course, there are more ways to use I to traverse array elements

Policy pattern of Android Design Pattern Policy pattern definition: defines algorithm families, which are encapsulated separately so that they can be replaced with each other. This pattern allows algorithm changes to be independen

Android and design pattern-Observer (Observer) PatternDr. Yan macro's book "JAVA and patterns" describes the Observer (Observer) mode in this way:　　The observer mode is the behavior mode of an object. It is also called the Publish/Subscribe mode, Model-View mode, and Source-Listener (Source/Listener) mode) mode or Dependents mode.The observer mode defines a one-t

Android design pattern-Observer Pattern Definition of the observer design pattern: defines one-to-multiple dependencies between objects. In this way, when an object changes state, all its dependent persons will receive notificatio

[Android Java] design pattern code: Observer Pattern The observer is like a person who is interested in many things, like music, electronic products, games, and stocks. Changes in these things can attract the attention of fans and always pay attention to them. In the code, we also have such a way to

in depth and difficulty are significantly higher than the open source articles on GitHub. As a result, there is a big gap between the articles on GitHub and the content in the book.InfoQ: There are a lot of classic books about Java design patterns, why do you want to write the design mode of Android source code?He Honghui: Books in Java

Singleton mode is the simplest of the 23 gof design modes.This mode is relatively independent from other modes. It is very interesting to control the number of Instantiation instances (instead of considering the instances generated for users, it is a clean mode that I like very much.In Android, the singleton mode is used in many places. This article uses inputmethodmanager, the Input Method Manager, as an e

Recently, I have been studying the design model. A good way to learn more is to write down my experiences. Record your understanding. Now I read the book head. frist design pattern. Good. Anyone who wants to learn the design model can read this book. Observer (Revised in December May 31) See the following structure:

1. Open/closed (OCP) Introduction: to scale, do not modify it. For example, I provide an external interface. If you want to update the API, do not modify it directly. Instead, provide another API and notify you when to switch to the new API. For example, this design pattern is everywhere. Each Android upgrade will provide some new APIs, and some older APIs will b

In this article, we introduce the combination pattern (Composite pattern), which is also known as part of the overall pattern (part-whole pattern), one of the structural patterns. The combination mode is simple, it considers a set of similar objects as an object processing, and combines the objects according to a tree
