If all three threads are calculating the finish after executing their calculation then the thread which is alive like main thread can sum up their task.<br /><br />javin paulhttps://www.blogger.com/profile/15028902221295732276noreply@blogger.comtag:blogger.com,1999:blog-8712770457197348465.post-85153330209165327982020-05-26T07:20:45.409-07:002020-05-26T07:20:45.409-07:00"When last thread completed their task, Main ..."When last thread completed their task, Main thread or any other thread can add result from each zone and print total population."<br />Here is a correction that, the last thread who calls the await() thread will add result from each zone i.e. barrier action.

Latches are precisely meant for this use - a one off event where some control thread wants to wait for N Unknownhttps://www.blogger.com/profile/17444833599021840083noreply@blogger.comtag:blogger.com,1999:blog-8712770457197348465.post-65901400168017776332013-04-16T00:27:32.240-07:002013-04-16T00:27:32.240-07:00Another key difference between CyclicBarrier vs Co...Another key difference between CyclicBarrier vs CountDownLatch is that later is advanceble. By advanceble, I mean thread can still continue e.g. Threads waiting on CountDownLatch can still continue after calling countDown() method but In CyclicBarrier, all thread must wait at barrier for other parties to arrive. That's why CyclicBarrier is not advanceable.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8712770457197348465.post-12550154991598171902012-09-11T17:09:03.126-07:002012-09-11T17:09:03.126-07:00hi,i hope you could help me coz i have a final pro...hi,i hope you could help me coz i have a final project in school and i don't know how to make it..my final project is " to create a program using inheritance and polymorphism and that program is about a company program and i need that program this coming september 24,2012.....i hope you help me this...Thanks a lot...

I think CyclicBarrier has real use case around multi-player games where Game should be start until all parties arrived and as you rightly pointed out initializing different parts of system etc.Javin @ transient vs volatile javahttp://javarevisited.blogspot.sg/2012/03/difference-between-transient-and.htmlnoreply@blogger.comtag:blogger.com,1999:blog-8712770457197348465.post-49059446553834194492012-08-08T11:10:00.405-07:002012-08-08T11:10:00.405-07:00Using a barrier in a parallel calculation isn'...Using a barrier in a parallel calculation isn't the best example. You'd end up tying resources needlessly while they could be doing something useful - such as calculating more parts. Most implementations use an intermediate results repository and take threads from a pool according to need.Ran Bironhttps://www.blogger.com/profile/13745439632196949633noreply@blogger.com
