FlowLayout in Swing

Question

This is my layout.

The two radio button should be below the welcome label.

like this:

__________________________
|                        | 
|        WELCOME         |
|         *  *           |
|                        |
|                        |
|                        |
|________________________|

the two asterisk are the radio buttons.

My Code:

northpanel.setLayout(new FlowLayout(FlowLayout.CENTER));
northpanel1.setLayout(new FlowLayout(FlowLayout.CENTER));


northpanel.add(welcome);  //this welcome text label

northpanel1.add(r1);   //this radio 1
northpanel1.add(r2);   //this radio 2


add(northpanel,BorderLayout.NORTH);
add(northpanel1,BorderLayout.NORTH);

    private static void createAndShowGUI ()
    {
        JFrame frame = new JFrame ();
        frame.setLayout (new BorderLayout ());
        frame.setDefaultCloseOperation (JFrame.DISPOSE_ON_CLOSE);

        JPanel northPanel = new JPanel (new GridLayout (2, 1));

        JPanel welcomePanel = new JPanel (new FlowLayout (FlowLayout.CENTER));      
        welcomePanel.add (new JLabel ("Welcome"));

        northPanel.add (welcomePanel);

        JPanel radioPanel = new JPanel (new FlowLayout (FlowLayout.CENTER));

        JRadioButton button1 = new JRadioButton ("Button 1", true);
        JRadioButton button2 = new JRadioButton ("Button 2", false);

        ButtonGroup group = new ButtonGroup ();
        group.add (button1);
        group.add (button2);

        radioPanel.add (button1);
        radioPanel.add (button2);

        northPanel.add (radioPanel);

        JPanel middlePanel = new JPanel (new GridLayout (3, 3));

        for (int i = 0; i < 3; i++)
        {
            for (int j = 0; j < 3; j++)
            {
                middlePanel.add (new JButton ("Button " + i + j));
            }
        }

        JPanel southPanel = new JPanel (new FlowLayout (FlowLayout.CENTER));

        southPanel.add (new JLabel ("Whose turn:"));
        southPanel.add (new JButton ("Reset"));

        frame.add (northPanel, BorderLayout.NORTH);
        frame.add (middlePanel, BorderLayout.CENTER);
        frame.add (southPanel, BorderLayout.SOUTH);

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

It looks like this (although you have to resize it a bit):

Answer 2

Add northpanel and northpanel to a panel having GridLayout(0, 1) then

add(panel, BorderLayout.NORTH);
