The following article Article I spoke very thoroughly, So I reprinted it. Abstract class and interface are two mechanisms supported for the definition of abstract classes in Java. It is precisely because of the existence of these two mechanisms

In the Java language, abstract classes and interface are the two mechanisms that support the definition of an abstraction class. It is the existence of these two mechanisms that gives Java a powerful object-oriented capability. Abstract class and

Java defines some methods that do not contain the method body, the implementation of the method body to the subclass of the class according to their own circumstances to implement, such a method is an abstract modified method of abstraction,

C #: I. abstract class:Abstract classes are special classes, but they cannot be instantiated. In addition, they have other characteristics of the class. It is important that abstract classes can include abstract methods, which are not supported

(1) OverviewAbstract class and interface support the definition of abstract classes in Java. It is precisely because of the existence of these two mechanisms Only in this way can Java provide powerful object-oriented capabilities. Abstract class and

I haven't seen such an incisive article for a long time! The author wrote it too well! If you are learning Java or want to know about abstract classes and interfaces, do not miss it! I strongly recommend it! Differences between interfaces and

Interfaces and internal classes provide us with a more structured approach to separating interfaces from implementations. abstract classes and interfaces are two mechanisms for defining abstract concepts in the Java language , and it is their
