assigning a value to a class variable, the type of the variable can either use the class itself, or it can use the superclass of the class. It is as if we were describing a sparrow or a magpie in the sky, usually saying "a sparrow is flying" or "a magpie is flying". But if you want to ignore their specific type, then you can say "a bird is flying."Similarly, when Duck objects and object Chicken types are hidden behind super-types Animal , Duck objects and Chicken objects can be exchanged for us

In Java and other object-oriented design patterns, there are 6 main types of relationships between classes and classes: Dependency, association, aggregation, composition, inheritance, implementation . Their coupling degree is increased in turn.Dependencies are defined as: for two relatively independent objects, when one object is responsible for constructing an instance of another object, or a service that

Design pattern for software development, its importance is self-evident, code can be reused, maintainable, extensible has always been the pursuit of software engineering! For a person who learns JavaScript, it may seem difficult to understand the design pattern, and it might not even be possible to use an FE that only transduction, with little interaction, but when you start using frameworks like Angular/ba

The design pattern is a set of ideas. However, I am a person engaged in coding. Sometimes I often think that we should consider how to implement the Code with application functions more skillfully. With the help of my masters and colleagues, I have done some work over the past few years. NET project, I love the C # language, so I found that C # has many special features when implementing some design

"Khan, so, what is an algorithm? reference a sentence in the book: An algorithm is the soul of a program.Specifically, the algorithm emphasizes details, and the design model emphasizes the overall design framework. For example, the

instead of implementing classes when calling the lower layer. Once the lower layer changes significantly, the upper layer will not fluctuate much.Assume that the following scenarios are met: Students Public class student {public void read (honglou) {// traverse each row for (line: honglou. getlines) {// a line of James reads this. see (line) ;}} public class honglou {public list At this time, James depends on a specific class of honglou. Once Xiaoming wants to read other books (using other imp

A small software has been restructured several times recently and is becoming more and more streamlined, but it still cannot meet its own requirements. After analysis, there is no design process and you can do it as you think of it. I have read the "big talk design mode" before, but I can still understand it when I look at it. It is hard to understand it later, mainly because I have no experience and I have

is often elusive. Often you will find that the factory method is clearly used, when the new requirements come, slightly modified, adding a new method, because the products in the class constitute a different hierarchical structure of the product family, it becomes an abstract Factory mode, and for the abstract factory model, when the reduction of a method of the provided products no longer constitute the product family, It evolved into a factory method model. Therefore, when using the factory m
