what uday did here was not creating the instance of the interface but he implemeted the interface through the anonymous class.Now the instance created is of that anonymous class which has implemented the interface and its reference is stored in the variable t.

You can't create an object without method implementations.
Anonymous inner classes allow you to do.
public interface MyInterface {
public void myMethod() ;
}
MyInterface myIntfObj = new MyInterface() {
public void myMethod() {
}
};
myIntfObj.myMethod();

Answer / anonymous
Hi Uday,
That's really nice however I think you have just created and anonymous class implementing the interface, and then invoking the wish method :)

hey uday u r wrong
In your program you are not created obj for interface, you have given anonymous implementation for 'Test' interface and instantiated that anonymous class only but not the interface.
for conformation call getClass() on 't'.(t.getClass())

Answer / neeraj
if we implements a class with an Interface then it will
compile time error i.e U must give the body of a method in
your class , so it is an anonymous class.We cannot create
Instance of an Interface.
