        Task<Void> task = new Task<Void>() {
          @Override public Void call() {
            for (int i = 1; i < 10; i++) {
              try {
              } catch (InterruptedException e) {
              updateProgress(i, 10);
            return null;
        ProgressBar updProg = new ProgressBar();
        Thread th = new Thread(task);
        StackPane layout = new StackPane();
        layout.setStyle("-fx-background-color: cornsilk; -fx-padding: 10;");
        stage.setScene(new Scene(layout));

    Using JavaFX UI Controls: Button | JavaFX 2 Tutorials and Documentation

    I am wondering, where should I add the following code mentioned in the above link:

    Image imageDecline = new Image(getClass().getResourceAsStream("not.png"));
    Button button5 = new Button();
    button5.setGraphic(new ImageView(imageDecline));

    2) Then, I would like to kill the thread if a user want to using the button. Is it possible to kill a thread in JavaFX?How should I kill a thread? Please advise
