I have a project made using Java.

I have a complex processing, something like from one single process i create 10 different threads, then the process waits for the other threads to complete processing. Now the threads that were created do some database processsing, and then finally generates the output. But the problem here is, the process that have been waiting, again needs to process all the data that was created in the threads that were created, sort of aggregated result.

I am almost clueless what needs to be done.

Regards

    You could use a java.util.concurrent.ConcurrentLinkedQueue. Have each thread put their results on the queue when they’re done. The main thread just watches the queue and processes the results as they come in.

    Another alternative is to use Futures. Instead of threads just use Futures for each of the processes. The main thread will block while waiting for each future to finish it’s processing.
