Answer / rushi shah

The above code given by Udaykiran gives the following error even before it is compiled:

Can not instantiate the type 'Test' type.

Which means that we can not create any object of interface.

Answer / sharath

we can create an object for interface but the there will be
of no use because interface methods are abstract in nature

Answer / kishore emani

Hi Anil, In this case uday sounds good!
As per your consideration if it is an anonymous class then
just remove that interface from our application and try to
compile it won't compile that code.
Here Test is an interface, for which to create the object
we need to provide the complete implementation for that
interface the same thing which uday did.
and again u check it if(t instanceof Test)
it is returning true that means t is an instance for Test.
and here the object is creating in the heap.
at finally here an instance is created for an interface.

Answer / guest

Hi all,

I think Udaya is right and i have tested in the same and its
working. But if you think about the way JAVA has to make
instances(e.g. A a = new A()) will not work. It will give
you compilation error. So there is something we are not able
to see. Even I am trying to get what this example actually
working.

Feel free to update me if I am wrong...☺
