Diffrence between calling the run() method.

If you extend any thread class , we should override the run method.
We can call that run method by using obj.start() or obj.run().
Just i want to know difference between them .
Is that start() method will create new Thread () ?

Yes. If you call the run method directly then it will be executed by the current thread. By calling start, a new thread is created and run is executed by that thread.

Actually, calling start does not create a new Thread, but it does create a new thread.

As said before, the difference is that start() will execute the run() method on a new thread, and run() will execute on the current thread.
This is a real stinker in examination; run() is called but the question lets you think that start() is called instead.
