Class Method
The essence of a class method is a single-piece method that lives in a single-piece class of this class. Three m
, all non-static constructors are also referred to as instance constructors. 2. Static ClassWe often want the class to contain only static members, and cannot be used to instantiate objects such as the console. A simple way to do this is to use a static class instead of setting the class's constructor to private. A static class can contain only static members and does not require an instance constructor because, by definition, it cannot be instantiated at all. However, a static class can have a

1. Why encapsulation?
Encapsulation is to hide the specific implementation details of data attributes and methods and only provide one int

Stack):
Storage: local variables;

Stores new objects;
Method):
Storage: class information (CODE), static variables, constant pools
JavaScript and Java, C # and other languages also have some object-oriented features, but in fine comparison, it will be found that these features are not real object-oriented, many places are using the object itself to simulate object
This article describes object-oriented programming (OOP) in PHP. I'll show you how to use object-oriented concepts to compile less code but better programs. Good luck to all of you.

prototype methods are added to the sub-class.Instance1.colors.push (' black '); Console.log (instance1.colors); // [' Red ', ' blue ', ' green ', ' black '] // [' Red ', ' blue ', ' green ']instance1.getname (); // CSSbook instance2.gettime (); // -Note: A subclass that wants to add a prototype method must pass a prototype object, one way to add it through the form of a point syntax, or it will be directly assigned to an
Overview
Process oriented: Write base code from top to bottom according to business logic
Function: A function code is encapsulated in a function, it will not need to be repeated later, only the function can be called
Object-oriented: classify and encapsulate functions to make development "faster, better and stronger ..."
