In PHP, for example, we can inherit a class like this:classperson{//Parent Class var $name; functionsay () {Echo"My Name:".$this-name; } }classTeacherextendsperson{//sub-class var $job; functionteach () {Echo"My Name:".$this->name. " My profession: ".$this->job;//$this->name inherit from par

Object-oriented Basic concepts1, object-oriented (OOP, OOD) three major features: encapsulation, inheritance, polymorphism. Note that abstraction is not one of the characteristics2, object-oriented programming is to abstract the data, and functional programming is to abstract the behavior. In the real world, data and behavior coexist, and so do programs, so we have to learn both of these programming ways.3, the concept of the class is an abstract conc

This article describes how to implement similar OOP inheritance based on prototype in javascript. The example shows how to use prototype to implement class inheritance in object-oriented programming, if you need it, refer to the example in this article to describe how javascript achieves inheritance similar to OOP Based on prototype. We will share this with you for your reference. The details are as follows

[C #] What about OOP polymorphism, Advice to cainiao developers: spend 10 thousand hours practicing Coding and do not waste 10 thousand hours Debugging (that is, reading code) Looking at the above UML diagram, we create an abstract Instrument class with an abstract method paly in the class, and all the subclasses inherit this class and implement the paly method.
