Stopping looping thread in Java
- by halfwarp
I'm using a thread that is continuously reading from a queue.
Something like:
public void run() {
Object obj;
while(true) {
synchronized(objectsQueue) {
if(objectesQueue.isEmpty()) {
try {
objectesQueue.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
obj = objectesQueue.poll();
}
}
// Do something with the Object obj
}
}
What is the best way to stop this thread?
I see two options:
1 - Since Thread.stop() is deprecated, I can implement a stopThisThread() method that uses a n atomic check-condition variable.
2 - Send a Death Event object or something like that to the queue. When the thread fetches a death event it exists.
I prefer the 1st way, however, I don't know when to call the stopThisThread() method, as something might be on it's way to the queue and the stop signal can arrive first (not desirable).
Any suggestions?
