        MyService service;
        String id;
        public MyThread(Stri         


        

Answer 1

You could make a class which extends Observable. Then your thread can call a method in the Observable class which would notify any classes that registered in that observer by calling Observable.notifyObservers(Object).

The observing class would implement Observer, and register itself with the Observable. You would then implement an update(Observable, Object) method that gets called when Observerable.notifyObservers(Object) is called.
