import javafx.application.Application;

public class SliderTwoThumbs extends Application {
   public void start(Stage stage) {
      //Instantiating the RangeSlider class
      RangeSlider slider = new RangeSlider(0, 100, 10, 90);
      //Setting the slider properties
      slider.setShowTickLabels(true);
      slider.setShowTickMarks(true);
      slider.setMajorTickUnit(25);
      slider.setBlockIncrement(10);
      //VBox to arrange circle and the slider
      VBox vbox = new VBox();
      vbox.setPadding(new Insets(75));
      vbox.setSpacing(150);
      vbox.getChildren().addAll(slider);
      //Preparing the scene
      Scene scene = new Scene(vbox, 600, 200);
      stage.setTitle("Slider Example");
      stage.setScene(scene);
      stage.show();
   }
   public static void main(String args[]){
      launch(args);
   }
}
