How to wait for a ThreadPoolExecutor to finish

Question

My Question: How to execute a bunch of threaded objects on a ThreadPoolExecutor and wait for them all to finish before moving on?

I\'m new to Thread

Answer 1

Here's a variant on the accepted answer that handles retries if/when InterruptedException is thrown:

executor.shutdown();

boolean isWait = true;

while (isWait)
{
    try
    {             
        isWait = !executor.awaitTermination(10, TimeUnit.SECONDS);
        if (isWait)
        {
            log.info("Awaiting completion of bulk callback threads.");
        }
    } catch (InterruptedException e) {
        log.debug("Interruped while awaiting completion of callback threads - trying again...");
    }
}
