Declaring an object that implements an interface

I'm trying to declare an object which must implement a specific interface. I thought the following would work in Java as it does in some other languages but I'm at a loss here:

Class<? implements **theInterface**> implementingObject

Any pointers would be appreciated

What you are declaring here isn't an object that implements an interface, but a class of an object which implements that interface. An object implementing an interface is simply declared as the interface type, i.e.

theInterface implementingObject;

for generics, you use "extends" regardless of whether it is a Class or Interface.

Class<? extends **theInterface**> implementingObject
