Basic Features The three basic characteristics of object-oriented are encapsulation , inheritance , polymorphism. Package The package is best understood. Encapsulation is one of the object-oriented features and is the main feature of object and class concepts.Encapsulation

book on programming Algorithms + Data St Ructures = Programs (Prentice Hall, 1975). Notice in Wirth ' s title, Algorithms come first, and data structures come. This mimics the programmers-worked at that time. First, they decided on the procedures for manipulating the data; Then, they decided-what structure-impose on the data to make the manipulations easier. OOP reverses the order:puts the data first, then

conditionstestException,We add a use case to test the boundary condition testBoundary ,How to get JUnit gree bar out and try it out, such as:Regardless of TDD, writing high-quality test cases is the most important, how to do unit testing, you can refer to the "Unit test of the road" this book. In addition, "Agile Java Chinese version" shows how to integrate Java and TDD effectively, through TDD Drive project development, interested can be consulted.(

JavaScript Object-Oriented Programming-object copy for quickly building inheritance relationshipsIn the preceding example, we create an object through the constructor and want the object to inherit from another constructor. We can

1. The constructor is also a general function , and the following creates a constructor.var person=function(name,age,job) { this. name=name; this. age= age; this. job=job; this. sayname=function() { Console.log (this. Name); } }(1) Call by using the constructor function1 var person=New person ("xiaoming", +, "Doctor"); 2 Person.sayname (); // xiaoming(2) using normal function calls1 Person ("Xiaoming", "Doctor"); 2 Window.sayname (); // x

Object-Oriented Programming, my thoughts Preface: This document aims to help my colleagues better understand object-oriented programming. This allows later users to take less detours, but many vulnerabilities and errors are inevit

in the previous example, we created the object through the constructor and wanted the object to inherit objects from another constructor.we can also directly target an object to achieve the purpose of inheritance, using subordinate steps:1. Copy an object 2. Adding attributes to new objects /** * Inherit properties a

__init__ (self, name, gender, score): super (Student, self). __init__ (name, gender) = ScoreBe sure to super(Student, self).__init__(name, gender) initialize the parent class, otherwise the inherited from Person Student will not name 和 gender . The function super(Student, self) returns the parent class that is inherited by the current class, that is Person , then calls the __init__() method, notes that the self parameter is passed in super() , implicitly passes in, __init__() and

JavaScript is an object-based (object-based) language, and almost all of the things you encounter are objects. However, it is not a true object-oriented programming (OOP) language because its syntax has no class (class). So what should we do if we're going to encapsulate th
