Adding a Buttongroup to a GUI OR making only one button selected at a time without a GUI

Question

I am currently working on a project that will take theorhetical orders for Pizza. One panel I'm making will have three options for Pizza. Thin crust, regular, and deep dish. My initial thought was to use a Buttongroup, because those make it so only one can be selected at a time. However that doesn't appear to work with JPanels, as searching here I discovered. However, none of the answers here I found mentioned any other way of doing it that kept them from all being selected at once.

The idea with the ButtonGroup is completely right. Look in the Java Api for further information.

EDIT

A minimal example would look like this:

import java.awt.GridLayout;

import javax.swing.ButtonGroup;
import javax.swing.JFrame;
import javax.swing.JRadioButton;
import javax.swing.SwingUtilities;

public class BottonGroupGui extends JFrame {

    public BottonGroupGui() {
        this.setDefaultCloseOperation(EXIT_ON_CLOSE);

        JRadioButton a = new JRadioButton("a");
        JRadioButton b = new JRadioButton("b");

        this.setLayout(new GridLayout());

        this.getContentPane().add(a);
        this.getContentPane().add(b);

        ButtonGroup group = new ButtonGroup();

        group.add(a);
        group.add(b);

        this.setVisible(true);
        this.pack();
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                new BottonGroupGui();
            }
        });

    }
}

You don't have to add the BottonGroup. Just assign the buttons (in my case JRadioButtons) to the group accordingly.
