How to create a dialog box with two questions

Question

I know how to create a simple dialog with "yes" or "no" buttons.

Object[] options = {"yes", "no"};

int selection = JOptionPane.showOptionDialog(
    gameView,
    "choose one",
    "Message",
    JOptionPane.YES_NO_OPTION,
    JOptionPane.QUESTION_MESSAGE,
    null,
    options,
    options[0]
);

But now I want to create a dialog with two questions. How do I do that?

I'd like the dialog to look like this:

You can really insert any content you want into a dialog. You are currently inserting a string ("choose one") but you could actually pass in an entire panel of controls:

import javax.swing.*;

public class Main {
    public static void main(String[] args) {
        // Create a button group containing blue and red, with blue selected
        final ButtonGroup color = new ButtonGroup();
        final JRadioButton blue = new JRadioButton("Blue");
        final JRadioButton red  = new JRadioButton("Red");
        color.add(blue);
        blue.setSelected(true);
        color.add(red);

        // Create a button group containing triangle and square, with triangle selected
        final ButtonGroup shape = new ButtonGroup();
        final JRadioButton triangle = new JRadioButton("Triangle");
        final JRadioButton square   = new JRadioButton("Square");
        shape.add(triangle);
        triangle.setSelected(true);
        shape.add(square);

        // Create a panel and add labels and the radio buttons
        final JPanel panel = new JPanel();
        panel.add(new JLabel("Choose a color:"));
        panel.add(blue);
        panel.add(red);
        panel.add(new JLabel("Choose a shape:"));
        panel.add(triangle);
        panel.add(square);

        // Show the dialog
        JOptionPane.showMessageDialog(
            null /*gameView*/, panel, "Message",
            JOptionPane.QUESTION_MESSAGE
        );

        // Print the selection
        if (blue.isSelected()) {
            System.out.println("Blue was selected");
        }
        else {
            System.out.println("Red was selected");
        }

        if (triangle.isSelected()) {
            System.out.println("Triangle was selected");
        }
        else {
            System.out.println("Square was selected");
        }
    }
}

This creates a popup which looks like this:

It doesn't look exactly like your image but that falls outside the scope of your question. If you want to change that, you'll need to play around with different types of layout. See this question for starters.
