FileHandler Java with Windows

Question

I am trying to write an Application which lists down the files from the server . Now I want to give users to open any file from the list (Windows) with any editor for example a text file and User opens with NotePad++.

Now is there anyway I can know that if user saves the file,if yes, then I would upload the file back to the server.

Use File#lastModified() to get the time at which the file was lastly modified.

There is a tutorial about Watching a Directory for Changes describing the WatchService which was introduced in Java 7. You can use this service to monitor files and directories:

WatchService watcher = FileSystems.getDefault().newWatchService();
Path dir = ...;
try {
    WatchKey key = dir.register(watcher,
                           StandardWatchEventKinds.ENTRY_CREATE,
                           StandardWatchEventKinds.ENTRY_DELETE,
                           StandardWatchEventKinds.ENTRY_MODIFY);
} catch (IOException x) {
    System.err.println(x);
}
