public class Main extends Application {

  @Override
  public void start(Stage primaryStage) {

    Group root = new Group();

    Scene scene = new Scene(root, 300, 150, Color.GRAY);

    Line redLine = new Line(10, 10, 200, 10);

    redLine.setStroke(Color.RED);
    redLine.setStrokeWidth(10);
    redLine.setStrokeLineCap(StrokeLineCap.BUTT);

    redLine.getStrokeDashArray().addAll(10d, 5d, 15d, 5d, 20d);
    redLine.setStrokeDashOffset(0);

    root.getChildren().add(redLine);

    Text offsetText = new Text("Stroke Dash Offset: 0.0");
    offsetText.setX(10);
    offsetText.setY(80);
    offsetText.setStroke(Color.WHITE);

    root.getChildren().add(offsetText);

    Slider slider = new Slider(0, 100, 0);
    slider.setLayoutX(10);
    slider.setLayoutY(95);

    redLine.strokeDashOffsetProperty().bind(slider.valueProperty());

    slider.valueProperty().addListener(
        (ov, curVal, newVal) -> offsetText.setText("Stroke Dash Offset: "
            + slider.getValue()));

    root.getChildren().add(slider);

    primaryStage.setScene(scene);
    primaryStage.show();
  }

  public static void main(String[] args) {
    launch(args);
  }
}
