Anonymous internal class

Anonymous internal class:

1. Anonymous internal classes are simply abbreviated internal classes.

2. Prerequisites for defining anonymous internal classes: Internal classes must inherit a class or implement interfaces.

3. Anonymous internal class format: new parent class or interface () {defines the content of the subclass}

4. In fact, the anonymous internal class is an anonymous subclass object. And the object is a little fat.

Abstract class absdemo {abstract void show ();} class Outer {int x = 3; Public void function () {New absdemo () {void show () {system. out. println ("x =" + x );}}. show () ;}} public class innerclass1 {public static void main (string [] ARGs) {New outer (). function ();}}
