How to get selected radio button from ToggleGroup

Question

I an working on JavaFX 8 and SceneBuilder. I created some radio buttons in the FXML File and specified a toggleGroup name to a radio button list in

Answer 1

The solution I got is:

ToggleGroup toggleGroup = new ToggleGroup();

Then set toggleGroup to the radio button; let's say r1 and r2

r1.setToggleGroup(toggleGroup);

r2.setToggleGroup(toggleGroup);

toggleGroup.setUserData(toggleGroup.getSelectedToggle().toString());

To print the data of RadioButton:

System.out.println("Selected Radio Button is " + toggleGroup.getUserData().toString());
