  • 0

Java executor has a pool of threads. If I have fixed length of pool (8 for example). Does all these 8 threads would live forever if application does not terminate? If some part of codes throw exception, does the thread in the pool would be dead?

On the other hand, if I want to terminate thread, how to terminate thread?

    Yes, they will live forever as long as the ExecutorService exists. You can shut them down by calling ExecutorService.shutdown(). As for the other part of your question, the javadoc explains it all:

    If any thread terminates due to a failure during execution prior to shutdown, a new one will take its place if needed to execute subsequent tasks.
