I am currently programming a multi processing tool with a GUI in JavaFx. I want to have your opinion about my code.
This is code snippet from my main class:
CountDownLatch latch = new CountDownLatch(selectedPaths.size());
ExecutorService executorService = Executors.newFixedThreadPool(2);
Converter converter = new Converter(parentApp.getMainController(), configuration, dbUtilSC, latch);
//Searching for all zip files and sorting according to directory
for (Path tracePath : selectedPaths) {
//progress++;
//updateProgress(progress, selectedPaths.size());
final List<Path> foundTraces = new ArrayList<>();
Files.list(tracePath).filter(f -> f.toString().contains("zip")).sorted().forEach(foundTraces::add);
//Checks for traces in xoraya directory
if (foundTraces.size() == 0) {
continue;
}
converter = new Converter(foundTraces);
//converter.getTraceFiles(foundTraces);
//Converter converter = new Converter(foundTraces, parentApp.getMainController(),
//configuration, dbUtilSC, latch, pgConvertTraces,selectedPaths.size());
executorService.execute(converter.runnableTask);
Thread.sleep(1000);
}
try {
latch.await();
executorService.shutdown();
if (!executorService.awaitTermination(800, TimeUnit.MILLISECONDS)) {
executorService.shutdownNow();
}
} catch (InterruptedException e) {
addLog(e.getMessage(), Level.ERROR);
executorService.shutdownNow();
}
