how do I set time limits for individual threads in a thread pool?

how do I set time limits for individual threads in a thread pool..? The parent thread need not wait until eve开发者_如何学Gory thread finishes and returns back. Instead it should fetch the next job(runnable/callable) and submit to the thread pool...

More context would be useful.

You might try using ExecutorCompletionService:

You can add a task to the same pool, or another one which will cancel the first task after a given amount of time. If it has completed this does nothing.
