The only way to create a thread is using a thread class.
(Either by extending it or creating object elsewhere).
Runnable does very little contribution here. It's just
that, the thread object expects instance of a class which
should have run() (semantics) method and is called via
runnable interface. Runnable method doesn't create any
thread by itself (sounds dumb as everybody knows Runnable
is an interface).
Calling Thread's start() is the only way in java to spawn a
separate independed execution with in the application.
