RadioButton rb3 = new RadioButton("rb3");
RadioButton rb4 = new RadioButton("rb4");
ToggleGroup toggleGroup = new ToggleGroup();
toggleGroup.getToggles().addAll(rb1, rb2, rb3, rb4);
//設置選中
rb2.setSelected(true);
//通過ToggleGroup設置選中
toggleGroup.selectToggle(rb3);
//RadioButton 監聽改變
rb1.selectedProperty().addListener(new ChangeListener<Boolean>() {
    @Override
    public void changed(ObservableValue<? extends Boolean> observable, Boolean oldValue, Boolean newValue) {
    }
});
//ToggleGroup 監聽改變

    @Override
    public void changed(ObservableValue<? extends Toggle> observable, Toggle oldValue, Toggle newValue) {
    }
});

ObservableList<Node> children = root.getChildren();
children.addAll(rb1, rb2, rb3, rb4);
