thread priority question

[Men Gumani]

Hi guys,
I have a quick question about thread priorities, it is saying that "the runnning thread will be of equal or greater priority than the highest priority threads in the pool", my question is, if the scheduler give the control to some thread and during that time slot some other thread's priority value is bumped to be higher than the current running thread, is the control immediately returned from the running thread back to the scheduler or the thread will finish the current time slot allocated to it and then return the control to the scheduler?
Thanks.

Yes it is.
Anyway you do NOT need to understand the behavior of the scheduler IN DEPTH for the SCJP exam. If you need to discuss further, you could use the Java intermediate forum.

Thanks, Devaka. I don't want to dig deep into the details, I am just curious about the statement in the book "at any given time the current running thread usually will not have a priority that is lower than any of the thread in the pool" is not completely right since even the priority of the running thread is changed to be lower than some of the threads' in the pool, as long as the time slot is not expiring, the current running thread will not return the control back to the scheduler and it is running with a lower priority than some thread in the pool.
Please forgive my ignorance.
