What can cause a thread to stop executing? 1) The program exits via a call to System.exit(0); 2) Another thread is given a higher priority 3) A call to the thread's stop method. 4) A call to the halt method of the Thread class Answers 1,3 ( or 2 ?) Can I answer 2 also ? As it is not true always.

hi there i think if u call the yeild() method on the current lower-priorty(lower cause another thread has been given higher priority), the thread schedular will c there's a higher-priority and will probably execute the higher-priority thread moving the lower-priority thread into ready-to-run state.

Drophinboy, but option 2 didn't mentioned call to yield() or result of yeild().

hi Ishaan i don't think the thread scheduler checks for higher-priority threads unless the current thread yields/dies/interuppted, so just increasing another thread's priority won't stop the current thread.

Answer is 1, 2, and 3. 1 will always stop it from executing 2 can on some machines cause it to stop. Not guaranteed, but question says can cause a thread to stop 3 will stop it from executing 4 there is not halt method Bill

Hi i think 2 is correct because even in time slicing the thread will be stopped from execution atleast for a while and in other os it will have to relinquish control any way any comments???
I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to
run our stuff on 16 servers instead of 3.
