### Question:
App { public static void main(String[] args) { ExecutorService executor = null; try { MessageQueue msgQueue = new MessageQueue(); LOGGER.info("Submitting TaskGenerators and ServiceExecutor threads."); Runnable taskRunnable1 = new TaskGenerator(msgQueue, 5); Runnable taskRunnable2 = new TaskGenerator(msgQueue, 1); Runnable taskRunnable3 = new TaskGenerator(msgQueue, 2); Runnable srvRunnable = new ServiceExecutor(msgQueue); executor = Executors.newFixedThreadPool(2); executor.submit(taskRunnable1); executor.submit(taskRunnable2); executor.submit(taskRunnable3); executor.submit(srvRunnable); LOGGER.info("Intiating shutdown. Executor will shutdown only after all the Threads are completed."); executor.shutdown(); if ( !executor.awaitTermination(SHUTDOWN_TIME, TimeUnit.SECONDS) ) { LOGGER.info("Executor was shut down and Exiting."); executor.shutdownNow(); } } catch (Exception e) { LOGGER.error(e.getMessage()); } }  static void main(String[] args);  }### Answer:
@Test public void test() throws IOException { String[] args = {}; App.main(args); }
