polymorphism vs encapsulation

Three object-oriented features-inheritance, encapsulation, polymorphism, and ---- Polymorphism We have briefly understood the three main characteristics of object-oriented, and I have also roughly explained some of them. Recently, I have seen a deeper explanation on some of the blogs of some other people, I want to add more information. Sealing 1.

Javascript is based on three main characteristics of objects (encapsulation, inheritance, polymorphism) and javascript polymorphism. Javascript is based on the three features of objects and the three features of C ++ and Java object-oriented, which are encapsulation, inheritance, and

Three major Java features: encapsulation, inheritance, polymorphism, and three major Polymorphism I. Encapsulation Encapsulation is to classify the commonalities (including attributes and methods) of the same class into a class for convenient use. Concept: In the object-orie

It is suitable for students with unclear class and object content. It is only for learning and sharing. Thank you.// Create a Pointtest class, which uses attributes x and y to represent the Coordinate Position of a vertex and cal

First, review:1, the process: The core is the process, the process is the steps to solve the problem, that is, what to do first, what to do, based on process-oriented design procedures, like in the design of a pipeline, is a mechanical thinking method.Pros: Complex questions to simplifyCons: Poor scalability (holding a body)Application scenario: Linux kernel, httpd,git2, Object-oriented programming: The core is the object, to understand the object should regard themselves as God, in the eyes of

inheritance, encapsulation, and polymorphism, which are also key to the popularity of object-oriented objects. Packaging The default value for a property of a class in Java is not private, and to hide the property's method, you can add a private modifier to restrict access only within the class. For private properties in a class, it is given a method (Getxxx,setxxx ()) to access the private property, gu

() method and the Name property in the Cat class are missing from the above code. So be careful with the upward transformation!Multiple inheritanceJava inheritance is single inheritance, but multiple inheritance can be achieved!Although a subclass can inherit only one parent class, subclasses of subclasses may also subclass the child class.For example, Class C inherits Class B, Class B inherits Class A, so the Class A is the parent of Class B, and Class B is the parent class of Class C.Disadvan

JavaScript is based on the three main features of the object and the three main features of C++,java object-oriented, both encapsulation (encapsulation), Inheritance (inheritance), and polymorphism (polymorphism). But the basic concept is the same as the way it is implemented. In fact, in addition to the three major fe

();}Note that the parameter type of this function is shape, which means that it is possible to place an instance of Round, line, or Triangle class, when: Round R; Drawshape (R);That is, you can draw a circle when: Line L; The drawing is a line. Now you can probably see the flexibility that abstract classes (interfaces) bring to your code. And we can add subclasses to the shape parent class at any time.Transferred from: http://blog.chinaunix.net/uid-20791902-id-291984.html(
