Which of the following calls will not stop a thread from executing ?
Assume that the thread is already started.

Why correct answer is

start()
It will throw an exception as the thread is already started.

As soon as we have exception, the thread will not execute any longer and it will stop a thread? Or I'm missing something.

That is not true. The caller thread will receive the exception. Not the thread on which you have called start. That will keep on running normally. Also, receiving an exception doesn't mean that the thread has stopped.

Many THX

Also, receiving an exception doesn't mean that the thread has stopped.

But a thread that calls start() on itself, and must obviously have already been started in order to do so, will terminate? I believe I can demonstrate that.

[admin]

Not necessarily. You can put the call to start() within a try/catch block.

Ah, I see thanks.
