Blocks until all tasks have completed execution after a shutdown request, or the timeout occurs, or the current thread is interrupted, whichever happens first.

Usage

protected void shutdownAndAwaitTermination(ExecutorService pool) {
    pool.shutdown(); // Disable new tasks from being submitted
    try {/*from   w w w.j  ava 2s  .  c o  m*/

            // Wait a while for tasks to respond to being cancelled
            if (!pool.awaitTermination(10, TimeUnit.SECONDS))

        }
    } catch (InterruptedException ie) {
        // (Re-)Cancel if current thread also interrupted
        pool.shutdownNow();
