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.");
}
});
