Encapsulation, inheritance, and polymorphism introductory tutorials: 10 recommended zero-based introductory tutorials on encapsulation, inheritance, and polymorphism

The content explained in this section is encapsulation, inheritance, polymorphism, overloading and rewriting. Preface: PHP's object-oriented is the same as JAVA's object-oriented. They are divided into three major characteristics: encapsulation, inheritance, and polymorphism. These three features optimize object-oriented in many aspects. These three characteristics are also issues that need to be considered when developing object-oriented. Encapsulation in object-oriented What is encapsulation? Encapsulation: Encapsulate abstracted data and operations on the data together. The data is protected internally. Other parts of the program can only operate on the data through authorized operations (member methods). As mentioned above, abstraction is to extract the common attributes and behaviors (methods) of a class of things to form a template (class). This method of studying problems is called abstraction. Just like our bank account, no matter whose account it is, it includes an account number and password, and there are also some common methods for withdrawing money, making deposits, and checking balances. Our idea of ​​encapsulation is:

##Introduction: The content explained in this section is encapsulation, inheritance, polymorphism, overloading and rewriting

2. C# Basic knowledge arrangement: Basic knowledge (2) Class

Introduction: Classes are the basis of object-oriented languages. The three major characteristics of classes: encapsulation, inheritance, and polymorphism. The most basic feature is encapsulation.

3. Java: Classes and Inheritance

##Introduction: For object-oriented programming languages, classes are undoubtedly the most important foundation. The four major features of abstraction, encapsulation, inheritance, and polymorphism are inseparable from classes. Only the existence of classes can reflect the characteristics of object-oriented programming. Today we will learn some knowledge about classes and inheritance.

Three-dimensional surface objects PHP three major object-oriented features Learn to fully understand abstraction, encapsulation, inheritance, and polymorphism

Introduction: Three-dimensional surface object: Three-dimensional surface object PHP three major characteristics of object-oriented learning to fully understand abstraction, encapsulation, inheritance, polymorphism: three major characteristics of object-oriented: encapsulation, inheritance , Polymorphism First, let’s briefly understand abstraction: When we define a class earlier, we actually extract the common attributes and behaviors of a class of things to form a physical model (template). This method of studying problems is called Abstract 1. Encapsulation Encapsulation is to encapsulate the extracted data and the operations on the data together. The data is protected internally, and only authorized operations (methods) in other parts of the program can operate on the data. PHP provides three access control modifiers: public means global, internal to this class, class
