public class Main extends Application {

  @Override

    Scene scene = new Scene(root, 300, 150);
    stage.setScene(scene);
    stage.setTitle("Sample");

    Task<Integer> task = new Task<Integer>() {
      @Override protected Integer call() throws Exception {
          int iterations;
          for (iterations = 0; iterations < 100000; iterations++) {
              if (isCancelled()) {
                  break;
              }
              System.out.println("Iteration " + iterations);
          }

  task.run();

  //  root.getChildren().add(t);


    stage.show();
  }

  public static void main(String[] args) {
