[B]Is creating a subclass of Thread done like this:
Yes, that is correct.
Because java supports single inheritance, Thread can be the only superclass.
That is true but if you need to, you can implement Runnable and then extend a different class.
There is no need to include a run method because it is not implementing a runnable interface.
That is also true, but if you dont override run() then your class wont do anything. Check out the API for Thread, it states the run method 'does nothing then returns'. So you'll have to do something or there is no purpose in writing a class that extends Thread or implements Runnable. hope that helps
