### Question:
App { public static void main(String[] args) { var counterDateValues = 0; var counterExceptions = 0; var callableDf = new DateFormatCallable("dd/MM/yyyy", "15/12/2015"); var executor = Executors.newCachedThreadPool(); var futureResult1 = executor.submit(callableDf); var futureResult2 = executor.submit(callableDf); var futureResult3 = executor.submit(callableDf); var futureResult4 = executor.submit(callableDf); try { var result = new Result[4]; result[0] = futureResult1.get(); result[1] = futureResult2.get(); result[2] = futureResult3.get(); result[3] = futureResult4.get(); for (var value : result) { counterDateValues = counterDateValues + printAndCountDates(value); counterExceptions = counterExceptions + printAndCountExceptions(value); } LOGGER.info("The List dateList contains " + counterDateValues + " date values"); LOGGER.info("The List exceptionList contains " + counterExceptions + " exceptions"); } catch (Exception e) { LOGGER.info("Abnormal end of program. Program throws exception: " + e); } executor.shutdown(); }  static void main(String[] args);  }### Answer:
@Test void shouldExecuteApplicationWithoutException() { assertDoesNotThrow(() -> App.main(new String[]{})); }
