Hi

How do I ensure all threads finish executing before main() continues. I used something like this:


for (int i : NUM_THREADS) {
threads.start();
}

for (int i : NUM_THREADS) {
threads.join(); // line 1
}

Does join() queue up the execution of threads ? For example, if threads 1 and 2 are running, main will wait at line 1 for thread 1 to die before going to the start of "for" loop. This will effectively rule out the concurrent execution model of the thread. Is there any other way of doing this? Or am I misinterpreting this?

Let me know
Thanks
M

Please do not cross-post the same question in multiple forums. It wastes people's time when multiple redundant conversations take place.
 
It is sorta covered in the JavaRanch Style Guide.
