Interface extending TimerTask

Question

I'm working on getting my interface to extend TimerTask in Java. But my code will give the next error: "Interface expected here" at the declaration of the interface.

import java.util.List;
import java.util.TimerTask;


public interface IEffectenBeurs extends TimerTask {

   public List<IFonds> getInfo();

   public void run();

}

`TimerTask` is a class. Interfaces can only extend other interfaces. — Vince, Mar 29 '16 at 13:35
You should consider using a `ScheduledExecutorService` instead of a `Timer`. — Mark Rotteveel, Mar 29 '16 at 13:58

TimerTask is an abstract class. Therefore an interface can't extend it. Your IEffectendBeurs could either extend Runnable or you could transform it to an abstract class too.
