Answer 1

It's closing opened dialog in 2 second.

dialog = new Dialog<>();
dialog.setTitle("It's a dialog!");
dialog.show();

    Thread newThread = new Thread(new Runnable() {
    @Override
        public void run() {
            try {
                Thread.sleep(2000);
            } catch (InterruptedException ex) {
                Thread.currentThread().interrupt();
            }

            Platform.runLater(new Runnable() {
                @Override
                public void run() {
                    dialog.close();
                }
                });
            }
    });
    newThread.start();
