How to add thread in ThreadPoolExecutor to shutdownhook

Question

I want my application finish task submitted, and try to use Runtime.addShutdownHook(). but how can I add the thread in ThreadPoolExecutor to ShutdownHook?. Is it possible to get the thread in pool? I think the pooled thread will be killed on kill command ( linux)

Answer 1

Why not just do something like:
          final ThreadPoolExecutor executor = null;
          Runtime.getRuntime().addShutdownHook(new Thread() {
               @Override
               public void run() {
                    int fiveSeconds = 5;
                    try {
                         executor.awaitTermination(fiveSeconds, TimeUnit.SECONDS);
                    } catch (InterruptedException e) {
                         // ignore - we're shutting down
          });-Muel
