Hi Rajareddy, When you call the run method directly a separate call stack is not created and it runs as a part of the same call stack from the method which it is called.Eventually it doesnt run concurrently with other threads.
Yes, the answer is that you can call run() method, just like any other method. But that runs it in the current thread. If you want to run it in another thread, you must use the API of Thread class to start a new thread, which will then call run() in the new thread.
Betty Rubble? Well, I would go with Betty... but I'd be thinking of Wilma.
