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

public class MyControler {
    @FXML
    private ToggleGroup myToggleGroup;

    @FXML
    public void initialize(){
        //the simplest way to print current value (text of the selected radio button)
        System.out.format("Selected Radio Button: " + ((RadioButton)myToggleGroup.getSelectedToggle()).getText());

        //register on change event
        myToggleGroup.selectedToggleProperty().addListener(new ChangeListener()
        {
            @Override
            public void changed(ObservableValue observable, Toggle oldToggle, Toggle newToggle)
            {
                //print new selected value after change
                System.out.println("Selected Radio Button: " + ((RadioButton)newToggle).getText());
            }
        });
    }

    //sample method to set radio button (unselect all if group don't contain value)
    private void setRadioButtons(ToggleGroup toggleGroup, String value) {
        for (Toggle t : toggleGroup.getToggles()) 
            t.setSelected(((RadioButton) t).getText().equals(value));
    }

    //sample method to set radio button (select existing value or do nothing)
    private void setRadioButton(ToggleGroup toggleGroup, String value) {
        for (Toggle t : toggleGroup.getToggles()) 
            if(((RadioButton) t).getText().equals(value)) 
                t.setSelected(true);
    }
}
