I think if you extend 'Thread', you cannot extend any other class.
But if you implement 'Runnable' you still can extend some class and implements other interfaces if you want to.

Other than that I don't know any differences.

note that "Thread" class also implements "Runnable" interface
that is why we can call

Thread t = new Thread(new Thread());

Generally implementing Runnable is more common than extending Thread class. Extending the Thread class doesn't give you much that you can use...
