The use of anonymous inner classes is to access the data of
outer class.Even private data also we can access.

button.addActionListerner(new ActionListener(){
public void actionPerformed(){}
});

here we are using anonymous class to implement
ActionListener interface.If at all we are using other class
that implements ActionListener interface and passing that
obj into

button.addActionListener(obj);

In this method we cant access the private variables of the
class that call button.addActionListener();
