How do I get which JRadioButton is selected from a ButtonGroup

I got similar problem and solved with this:

import java.util.Enumeration;
import javax.swing.AbstractButton;
import javax.swing.ButtonGroup;

public class GroupButtonUtils {

    public String getSelectedButtonText(ButtonGroup buttonGroup) {
        for (Enumeration<AbstractButton> buttons = buttonGroup.getElements(); buttons.hasMoreElements();) {
            AbstractButton button = buttons.nextElement();

            if (button.isSelected()) {
                return button.getText();

        return null;

It returns the text of the selected button.
