public static void main(String[] args) throws Exception {
WatchService watchService = FileSystems.getDefault().newWatchService();
Path path = Paths.get("G:\\");
path.register(
watchService,
StandardWatchEventKinds.ENTRY_CREATE,
StandardWatchEventKinds.ENTRY_DELETE,
StandardWatchEventKinds.ENTRY_MODIFY);
WatchKey key;
while ((key = watchService.take()) != null) {
for (WatchEvent<?> event : key.pollEvents()) {
System.out.println("Event:" + event.kind() + ", File：" + event.context());

}
WatchService added in Java7 for NIO solution.
