JavaFX many task work in GUI

I ran a thread that updates the open time of the application. It works well. I've expanded the Service class. The time from this task update my GUI, textField by Platform.runLater

@Override
protected Task<Void> createTask() {
    return new Task<Void>() {
        @Override
        protected Void call() throws Exception {
            while (!isCancelled()) {
                if (isPause == false) {

                    try {
                        Platform.runLater(() -> {
                               currentTimeInApp = currentTimeInApp + 1;
                               upPanelController.timeInApp.setText
                                    (currentTimeInApp.toString());
                            }
                        });
                        Thread.sleep(1000);
                    } catch (InterruptedException e) {
                        System.out.println(e.getMessage());
                    }

                    if (isCancelled())
                        break;
                }
            }
            return null;
        }
    };
}

I would like to run a second thread which also updates GUI. I can't run the same thread. Can two independent threads be updated GUI ? Most of the information on the internet is dedicated to one topic. Thank you for every suggestion

Yes, you can use as many threads as you like. You just have to make sure that you always do the GUI update via Platform.runLater.
