Passing Interface Class as a Parameter in Java

Question

I have an interface:

public interface IMech {  } 

and a class that implements it

public class Email implements IMech {  } 

and a third class that has this method implemented:

public void sendNotification( Class< IMech > mechanism ){ } 

now I'm trying to call that method like so

foo.sendNotification(Email.class); 

but i keep getting an exception saying:

The method sendNotification(Class<IMech>) in the type RemediationOperator is not applicable for the arguments (Class<Email>) 

Shouldn't this work if it interfaces that class?

Answer 1

Perhaps you need

public void sendNotification( Class<? extends IMech> mechanism ) {
