Declaring an object that implements an interface

Question

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

Answer 1

对于泛型，无论它是类还是接口，都使用“扩展”。

Class<? extends **theInterface**> implementingObject

Answer 2

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, ie

theInterface implementingObject;
