In the above example, we have created a classPolygon. It has a single methoddisplay(). We then created an anonymous class that extends the classPolygonand overrides thedisplay()method. When we run the program, an objectp1of the anonymous class is created. The object then calls thedisplay()...
We usually use anonymous classes when we have to modifyon the flythe implementation of methods of some classes. In this case, we can avoid adding new*.javafiles to the project in order to define top-level classes. This is especially true if that top-level class would be used just one t...

Anonymous classes are often used in graphical user interface (GUI) applications. Consider the JavaFX example HelloWorld.java (from the section Hello World, JavaFX Style from Getting Started with JavaFX). This sample creates a frame that contains a Say 'Hello World' button. The anonymous class exp...
Inside the anonymous class. Explanation In the above program, we created a public classMainthat contains amain()method. Themain()method is the entry point for the program. Here, we also created 2 classesSampleandDemo. We created an anonymous class by extending theSampleclass into theDemoclass...

Example: Java 8 In this example, we are creating an anonymous class that implements add() method to add integer type values. We executed this method using the Java 8 compiler. Since this feature was added to Java 9. So, the Java 8 compiler throws an error. See the example below. ...
Example: classOuter{staticclassNested{}} Astatic nested classcan be instantiated like this: classOuter{// outer classstaticclassNested{}// static nested class}classDemo{publicstaticvoidmain(string[]args){// use both class namesOuter.Nestedn=newOuter.Nested();}} ...
They are expressions, so we can define the class in another expression, for example. View Code Syntax of Anonymous Classes Thenewoperator Thenameof an interface to implement or a class to extend Parenthesesthat contain the arguments to a constructor.Note:interface has no constructor, so use an ...
