Preface: Robert C. martin summarizes the principles that should be followed in Object-Oriented Design (OOD). These principles are called "prinles les of OOD ", for more information about principles of OOD, see object menter. This article introduces the interface separation principle in "Principles of OOD": interface segregation principle (ISP ). You can view the original
Preface: When defining interface members, you do not need to write access controllers because they are public by default and can only be public. When a class needs to implement this interface, its members must be made public. I have been doing this for a long time.

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)
Who said the interface cannot have code? -- Kotlin interface introduction (KAD 26), kotlinkad By Antonio Leiva Time: Jun 6, 2017 Link: https://antonioleiva.com/interfaces-kotlin/ 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

Interfaces do not provide any implementation. Interfaces reflect the design philosophy of standardization and implementation separation. Ii. Interface Defi

BACKGROUND The current mainstream H5 page dynamic access to content is the use of Ajax asynchronous request background data to achieve real-time refresh, is actually using the Get/post HTTP request backend interface, and then the returned data (typically JSON or XML format) rendered on the page, Therefore, to ensure the correctness of the H5 page i
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

interfaces, inheritance, and polymorphism1. Inheritance and polymorphism is an important part of the object-oriented development language, which makes the architecture of the whole program very flexible and reduces code redundancy.2. Inheritance: reuse of defined classes;3. Polymorphism: Can dynamically adjust the call of the object, reduce the dependency relationship;4. Interface: Classes in Java can implement multiple interfaces, which are used to e

An interface is a form of constraint that includes only member definitions and does not contain content that is implemented by members. with interfaces (interface), you can specify which methods a class must implement, but you do not need to define the specific contents of those methods. We can define an interface by interfac
But there is no corresponding mechanism in JavaScript, but JavaScript is very flexible, we can use its features to imitate interface, but we need to add some methods to do check action We can still use programs to simulate the implementation of JavaScript interface interfaces. In general, the implementation of the simulation interface has the following three way
