If I understand my recent reading correctly, you are correct. The JVM decides which thread runs when. You can use the sleep method to *try* to control which thread runs at what time, but it is not guaranteed to work.

The output will be 0 1 2.

Note that you are not starting a new thread of execution, but just calling the method run().

To start a thread, you have to use start() method.

you are correct surendra. I have a question ..when we start a thread by extending the Thread class, should we not override the start method ?

No. Only run() method code would run in a separate thread of execution.
start() method is to start a new thread of execution.

Now that was a good catch.
