We use the Public and Private keywords in encapsulation and interfaces to encapsulate object members. After encapsulation, the product hides internal details and only provides them to users.Interface).
An interface is a very useful concept that assists us in abstract thinking. In real life, when we think of an appliance, we often thin
I. Specification for abstract class definitions1. PHP5 supports abstract classes and abstract methods2, the definition of abstract class can not be instantiated3. If an abstract method is declared in any of the classes, the class must be declared as an abstract class4, is defined by the abstract method can only declare its invocation method (parameters), can not define its specific function implementation5, continue the subclass of the abstract class must define the parent class (abstract class)
In the above interface-related design pattern (1), detailed description of the custom service mode and adapter mode, the following we look at the third interface-related mode: proxy mode.Proxy ModeDefinition: provides a proxy for an object to control access to the object.Classification:
Remote Proxy-Provides a local area network representative object for different geographic objects. (Similar to cl
Summary
Clientsshoshould not be forced to depend upon interfaces that they do not use.Users cannot be forced to rely on interfaces they do not use. In other words, it is better to use multiple dedicated interfaces than to use a single total interface.It contains two meanings:-Interface design principle: the interface design should follow the minimum interface pri

Compared with Java, the Kotlin interface allows you to reuse more code.
The reason is very simple:You can add code to your interface. If
Interface (Interface)
is a collection of abstract methods , and interfaces are usually declared with interface.
A class inherits the abstract method of an interface by inheriting the interface.interfaces are not classes , and the way they are written is similar to classes, but they are different concepts.

I. Concepts of interfaces
An interface is a more thorough abstraction. Interfaces are abstracted from multiple similar classes. Interfaces do not provide any implementation. Interfaces reflect the design philosophy of standardization and implementation separation.

The core concept of Java: interface (interface)Interfaces are at the same level as classes, and in fact, interfaces are a special kind of abstract class.For example: interface ia{} public interface:The public interface is similar to a class where a file can have only one public int

Abstract class and interface, abstract class Interface1 abstract class 1.1 abstract class overview
In java, a method without a method body should be defined as an abstract method. If an abstract method exists in a class, this class must be defined as an abstract class.
Example:

Abstract class and abstract method and interface differences, abstract class interface differencesI. abstract classes
Abstract classes and specific classes are relative, not absolute. Abstract is a conceptual term, specifically a visible and touchable realistic object. The smaller the concept, the greater the abstraction degree, the larger the extension, and vice versa. Simply put, "man" is more abstract th
