Question

I'm using a blocking queue implementaion in my program.I would like to konw how long the thread will wait for a element to dequeue.? My client thred polls fro response, my server thread offers message. My code is as follows; ``` private BlockingQueue applicationResponses= new LinkedBlockingQueue(); ``` client: ``` Message response = applicationResponses.take(); ``` server: ``` applicationResponses.offer(message); ``` Will my client thread wait forever? i would like to configure that time..(eg: 1000ms)..is that possible?

Accepted Answer

Yes it will wait forever until you can take an element. You should use poll(time, TimeUnit) if you want to have a max wait time.

```
Message response = applicationResponse.poll(1, TimeUnit.SECONDS);
```
