Answer / sam e
The use of an anonymous inner class is to create a
non-reusable implementation of an abstract class or
interface. For example, a UI button that is Runnable can
implement its run method at the same place in code that it
is created.

Answer / sumit bansal
Anonymous class exist till the method or block (In which it
is defined) runs. After that it vanishes so it help to use
the memory efficiently.
in your code if you want a particular class once and that
is also in the method/block use anonymous class.
it is the best of my knowledge. if you know more please
reply me.

We can declare an inner class within the body of a method
without naming it. These classes are known as anonymous
inner classes
Very useful for controlled access to the innards
of another class. and useful when we need one instance of a
special class.

Answer / ashokkumar
Anonymous classes
1.These are one type of inner class that having no mame.
2.The syntax will come like
class a
{
public void mymethod ();
}
class b
{
a obja = new a(){//the anonymous class starts here
public void mymethod (){ //have to implement the methods of
//class 'a'
return "here we are implementing mymethod of class 'a'"
}
}; //when finishing anonymous classes we have to put";"
}
3.Here the anonymous class is consider as a sub class of
class 'a'.We can access all the variables and methods of
super class 'a' through the anonymous block,except local
variables,including private variables.
4.Through anonymous classes we can create instance for
Interfaces.

Answer / suneetha
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();
