How to randomly select a button in a ButtonGroup of JRadioButtons?

Question

I want to have a random radio button to be selected whenever this panel gets initialized, but I'm not sure how/if I can do that.

Is there a way to get a random button from the group and select it?

import javax.swing.*;

public class RandomPanel extends JPanel
{
    private ButtonGroup buttonGroup;
    private String[] buttonText =
            {
                    "Red",
                    "Mashed Potatoes",
                    "Metal",
                    "Running",
                    "Butts",
                    "Turquoise"
            };

    public RandomPanel()
    {
        setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
        setBorder(BorderFactory.createTitledBorder("Random Selections"));

        buttonGroup = new ButtonGroup();
        for (String text : buttonText)
        {
            JRadioButton option = new JRadioButton(text);
            add(option);
            button.add(option);
        }
    }

}

What you can do is keep a list/array of all the radio buttons you create, and then set the selected by using the button group's setSelected() method, something like this

buttonGroup.setSelected(buttonsArray[randomButtonNum].getModel(), true);
