toggleButton1.setToggleGroup(toggleGroup);

toggleButton2.setToggleGroup(toggleGroup);

toggleButton3.setToggleGroup(toggleGroup);

  ToggleButton toggleButton1 = new ToggleButton("Toggle Button 1");
  ToggleButton toggleButton2 = new ToggleButton("Toggle Button 2");
  ToggleButton toggleButton3 = new ToggleButton("toggle button 3");

  toggleButton1.setToggleGroup(toggleGroup);
  toggleButton2.setToggleGroup(toggleGroup);
  toggleButton3.setToggleGroup(toggleGroup);
  
  HBox hbox = new HBox(toggleButton1, toggleButton2, toggleButton3);

  hbox.setAlignment(Pos.TOP_CENTER);

  Scene scene = new Scene(hbox, 800, 400);
