method without naming it. These classes are known as
anonymous inner classes.

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();
}
}

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.*/
}
