Interface recognition

[owls]

Is there a way I can recognize in an if statement whether a class implements a certain interface. I basically want a certain action to occur to objects that only implement an interface I have created.

Why would you want to do that ?

Anyway, this should do it :

Class cls = this.getClass().getSuperClass();

There are lots of methods in the Class class for looking into classes :

And what about

 instanceof

keyword?

AClass a = new AClass ();
//...
if (a instanceof MyInterface)
  //do stuff in that case
