You can also declare an inner class within the body of a
method without naming it. These classes are known as
anonymous inner classes.

explain Anonynous inner class?..

Answer / arjun

It is a class without any name. It is used when we want to
have an encapsulation(i.e. want to use an object of a class)
only once and never required again. we combine the object
creation and class code in a interesting way.

explain Anonynous inner class?..

Answer / shaik baji

Anonymous inner class comes in two forms

1)Normal Anonymous Inner Class
2)Parametrized Anonymous Inner Class

1) Normal Anonymous Inner Class:

Again the Normal Anonymous Inner class is two types

a)Extending the class by Anonymous Inner Class
b)Implementing the interface by Anonymous Inner
Class

a)Extending the class by Anonymous Inner Class

class One
{
void printOne()
{
System.out.println("One");
}
}
class AnonymousDemoByClass
{
public static void main(String Arg[])
{
One obj = new One(){
void printOne()
{
printTwo();
}
void printTwo()
{
System.out.println
("Two");
}
};
obj.printOne();
}
}

Output: Two

b) Implementing the interface by Anonymous Inner
Class

interface One
{
void printOne();
}
class AnonymousDemoByInterface
{
public static void main(String Arg[])
{
One obj = new One(){
public void printOne()
{
printTwo();
}
void printTwo()
{
System.out.println
("Two");
}
};
obj.printOne();
}
}

Output: Two

2)Parametrized Anonymous Inner Class:

Here we are implementing our Anonymous inner class as a
paramer to any method.

interface One
{
void printOne();
}

class ParameterizedAnonymousDemo
{
public static void main(String Arg[])
{
ParameterizedAnonymousDemo obj =
new ParameterizedAnonymousDemo();
obj.doSomething(new One(){
public void printOne
()
{

System.out.println("One");
}
});

}
public void doSomething(One objOne)
{
objOne.printOne();
}
}

explain Anonynous inner class?..

Answer / preetesh

An Anonymous class is an inner class that is not assigned a
name. It is defined and instantiated within arguments of a
method of the Outer Class.

Syntax is as follows:
----------------------
public class OuterClass
{
//some relevant code

methodName(new ClassName(){ }); /*It indicates compiler
that the code between the braces in the argument of the
method defines an anonymours inner class.*/
}
