advantages of anonymous class in java

Anonymous internal class summary in java and java Anonymous class Summary In the world of java, the anonymous internal

internal classes are widely used. For example, when the window is closed, append the following code: frame. addWindowListener (new WindowAdapter () {public void windowClosing (invalid wevent e) {System. exit (0) ;}}); note that the anonymous internal class has no name, so he has no Constructor (but if this anonymous internal

not have a constructor (but if this anonymous internal class inherits a parent class that only contains a parameter constructor, these parameters must be included during creation and the corresponding content must be called using the super keyword during implementation ). If you want to initialize its member variables, you can use the following methods:If it is

anonymous classes without the class keyword?1) to have the new operator, similar to the normal class instantiation of an expression.2) to implement an interface or inherit a class, the example above is to implement the HelloWorld interface.3) class body (body), where you ca

the name of the inner class is superfluous, soThe anonymous inner class is used.3, how to implement anonymous internal class? The implementation of an anonymous inner class is very si

Java Basics _ Inner classes: In Java, a class can be defined inside another class or inside a method, such that a class is called an inner class.The primary role of inner classes: using internal classes can reduce naming conflicts.Define location: An inner

this class, and become the anonymous inner class.2, you will want to define a callback function, but do not want to write a lot of code, you can consider anonymous inner class.3. Syntax:Class outerclass{ //Peripheral class fie

to write it as a separate class?The anonymous inner class is introduced at this time. Using an anonymous inner class implementation:1 Abstract classPerson {2 Public Abstract voideat ();3 }4 Public classDemo {5 Public Static voidMain (string[] args) {6 7

1. A Java program is a collection of classes.A class in a program has two kinds of arrangement structures. For example: classenclosingclass{..... Class anestedclass{......} } 2. In some special cases, a class is also placed within the internal definition of another class,

; public void F () { System.out.println ("in Anonymous F ()"); } }; } public static void Main (string[] args) { base base = Anonymousconstructor.getbase (.); Base.F (); }}Nested ClassesA nested class is also a class defined in a class

its own properties and methods, but it cannot be instantiated because the parent class is instantiated, The parent class does not change the properties and methods in the anonymous class private String name = "AAA"; The {///anonymous cl
