How to introduce the code related to Java multithreaded loop
This article introduces you how to introduce the code related to Java multithreaded loop, the content is very detailed, interested friends can refer to, hope to be helpful to you.
The Java multithreaded loop requires us to keep learning, and there are many issues that we care about each other all the time. Let's take a look at how to better use this programming language. When each iteration is independent of each other and completing the work of each iteration in the loop body is significant enough to cover the overhead of managing a new task, this sequential loop is suitable for parallelization.
Public voidParallelRecursive (final Executorexec
Listnodes,Collection results) {
For (Node n:nodes) {
Exec.execute (new Runnable () {
Public void run () {
Results.add (n.compute ())
}
});
ParallelRecursive (exec,n.getChildren (), results)
}
}
PublicCollectiongetParallelResults (Listnodes)
Throws InterruptedException {
ExecutorService exec=Executors.newCachedThreadPool ()
Queue resultQueue=newConcurrentLinkedQueue ()
ParallelRecursive (exec,nodes,resultQueue)
Exec.shutdown ()
Exec.awaitTermination (Long.MAX_VALUE,TimeUnit.SECONDS)
Return reslutQueue
}
However, the above procedures cannot deal with situations where there is no solution, and the following procedures can solve this problem.
Public class PuzzleSolverextendsConcurrent
PuzzleSolver {
...
Privatefinal AtomicInteger taskCount=new AtomicInteger (0)
ProtectedRunnable newTask (P pmae M m M J J Noden) {
Return new CountingSolverTask (pdym _ m _ n)
}
ClassCountingSolverTask extends SolverTask {
CountingSolverTask (P pos,Mmove,Node prev) {
Super (pos,move,prev)
TaskCount.incrementAndGet ()
}
Publicvoid run () {
Try {
Super.run ()
}
Finally {
If (taskCount.decrementAndGet () = = 0)
Solution.setValue (null)
}
}
}
}
On how to carry out Java multithreaded loop related code introduction is shared here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
