Java Study Notes 21 --- supplementary description of internal classes of members (2) (corrected), Study Notes 21 ---
Fixed: the original article was a bit incorrect, mainly concerning the subclass of the member's internal classes.
Due to my cognitive limitations, I think that the subclass of the internal class should also be an internal class.The points of intern
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 that give Java powerful object-oriented capabilities. Abstract class and interface have great similarity in support for the definition of abstract classes
classes are inherited, ordinary class extents inner class. And this time the code to be a bit special to deal with, specifically, see the following examples: public class Inheritinner extends Withinner.inner { //Inheritinner () is not compiled, be sure to add formal parameter Inheritinner (withinner WI) { wi.super (); } public static void Main (string[] args) { Withinner wi = new Wi
abstract classes and interfaces may lie in the common characteristics of the objects in their system, which are constantly being drawn upward. They can all be used for polymorphic implementations. Second, the internal class1. What is an internal class?As the name implies, an inner class refers to a class that is defined inside another class. We know that one of the basic forms of Java writing is a class, a
Summary:Based on the reuse of Java classes, this paper presents a comprehensive description of the inheritance and polymorphism of object-oriented two major features.First of all, we introduce the essence and significance of inheritance, and discuss the similarities and differences of inheritance, composition and proxy in the reuse of classes. Shortly thereafter,
In the Java language, abstract class and interface are two mechanisms that support the definition of abstract classes. It is because of the existence of these two mechanisms that gives Java a powerful object-oriented ability. Abstract class and interface have a great similarity in support of the definition of abstract classes
Recently learned the development of cross-platform audio and video communications under the Android platform, although there are many open source projects available on the Internet for our participation. But the audio and video effect is very general, there are a lot of unstable factors, after all, is open source. In China I found a better audio and video communi

toInner Inner = new Inner ();Inner.inner_f2 ();}public static void Main (string[] args) {New Outer (). OUTER_F3 ();}}Generating a static inner class does not require an external class member: This is the difference between a static inner class and a member inner class. Objects of the static inner class can be generated directly: Outer.Inner in = new Outer.Inner (); It does not need to be generated by generating an external class object. This actually makes the static inner Class A top class (un

The quality of a software design depends to a large extent on its overall architecture. The overall architecture is actually your abstract framework for the entire macro business, when the structure of the high-level abstraction layer representing the business logic is reasonable, you only need to consider some algorithms and specific business implementations. When you need to develop another similar project, your previous ab
Use internal and anonymous classes to optimize Java code-general Linux technology-Linux programming and kernel information. The following is a detailed description. By modifying Java language specifications, Java 1.1 significantly simplifies the implementation of some practical structures. Among those modifications, in
Why use internal classes?1. Internal classes provide better encapsulation, only external classes can access internal classes2. Inner classes can inherit an interface independently, independent of whether an external class inherits the interface3. The properties and methods in an inner class are not directly accessible
