modified the class it belongs to.Strategy: Define a series of algorithms, encapsulate them one by one, and make them interchangeable with each other. This mode allows the algorithm to be changed independently of the customer using it.Templatemethod: Defines the skeleton of an algorithm in an operation, and delays some steps into subclasses. Templatemethod allows subclasses to redefine some specific steps of the algorithm without altering the structure of an algorithm.Visitor: Represents an oper

1. Java Viewer mode (Observerpattern)(1) Overview:We use news apps in our lives, and when we are interested in a particular column, we tend to subscribe to this column of news, such as my interest in the military bar, I will subscribe to the military Bar news. In this case, once the military column news updates, the app will automatically pop up notifications to let us know.This is the observer pattern, she defines a one-to-many dependency between obj

Enterprise Development" is downright inconsistent, perhaps simply because the word "Enterprise" sounds cool, the author Brandon Goldfedder will be happy to let it appear in the title. Yes, this book is not amorites with what we often call "enterprise-level development", and it is a real introductory textbook of patterns. In commenting on Dr Shanhong's Java and m

experience reach a certain level, and it also means to summarize a lot of good design experience, however, it may not be the case that "no teacher can do anything", or you can say that, on the basis of level and experience, it is time for the system to learn the "mode, it is helpful to learn the experts' summary and verify your own shortcomings. This series of design patterns learning notes is actually a Learning Record for the

advancement of Metaprogramming in the past decade. I believe it would take the place of Loki ' s "Modern C + + Design" to become the Bible for C + + meta-programming.Introduction to Algorithms (2nd/3rd Edition)Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, and Clifford SteinIf you know nothing on algorithms, you never understand computer science. Definitely a classic on algorithms and data structures, that's everyone who's serious about computer science Must read. This contents of th

The essentials and patterns of software design (version 2nd) is the book on software design and design patterns published by Zhang Yi of garden in April this year. I got it in late May and read a chapter every night, after reading chapter 28 of the book on and off last night, I felt very deep. I used to have vague know

Working for n years, suddenly wanted to comb the knowledge about design and architecture. I would like to ask if there is any good book or material in this respect, more about the actual work, worthy of recommendation of excellent practice. Originally felt like "Enterprise Application Architecture Model" good, just a bit of translation is a little hehe, look very tired. Reply content: Working for n years, suddenly wanted to comb the knowledge abo

Overview When an object in the system has multiple states, these States can be converted, and the state mode can be used for different states of the object. The State mode separates the state of an object from the object and encapsulates it into a speci
