What is an anonymous class?
An anonymous class is a local class without a name. An anonymous class is defined and instantiated in a single succinct expression using the new operator. While a local class definition is a statement in a block of Java code, an anonymous class definition is an expression, which means that it can be included as part of a larger expression, such as a method call. When a local class is used only once, consider using anonymous class syntax, which places the definition and use of the class in exactly the same place.New Syntax for Anonymous ClassesWe've already seen examples of the syntax for defining and instantiating an anonymous class. We can express that syntax more formally as: new class-name ( [ argument-list ] ) { class-body }or: new interface-name () { class-body }
What is the purpose of anonymous class?
An anonymous class allows you to bind an unnamed ("anonymous") class for the purpose of leaving your class namespace relatively uncluttered in the source code. This is usually reserved for small classes with a simple function that is "inlined" into a larger class in order to make the source code smaller, albeit slightly less readable. While classes of any size may be anonymous, they should be small in size to avoid making the code less readable.

What is the meaning of anonymous classes for events in java?
Anonymous classes, basically, have no name. It combines the class declaration and the creation of an instance of the class in one step. If an event handler is not shared by multiple components there is no need to declare a class to handle the event. The handler can be implemented with the use of an anonymous inner class. i.e. : button1.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { JOptionPane.showMessageDialog(null, "You clicked button1."); } });
