An interface is not a class.

Hi Praveen,

there is simply no concept like a "global super interface" I think the reason is simply because it wouldn't make much sense to define an abstract global interface all classes must implement. With "Object" that's another thing because it doesn't only provide an abstract interface but instead "real" functionality which is required for all objects in Java to work properly with core concepts and APIs. I hope this makes it clearer.

But whenever you instantiate an interface, usually by making a class which implements that interface, that class extends java.lang.Object.
