After compiling error:

class, enum or interface expected ?

I had one mock question in which they had created an instantiated the interface

so i thought do objects of interface can be created ?

The anonymous inner class syntax is used to instantiate interfaces...

No you can't create instances of an interface. You can see an interface as a 100% abstract class. You need a concrete class.

Then you're not really creating an instance of the interface but a class that implements the interface.

no its not correct you are instantiating an interface.

you can use interfaces for polymorphic instantiation like this:


or for anonymous inner class instatiation like this:
