Adding an array of random values to a JList

So I'm trying to make it so that my JList consists of random values everytime I boot my program up (I was using a string array to randomize values from 2 different arrays). I have been struggling to get this working. The elements show when I use one array, but it doesn't work when I use the new array that consists of a string with 2 values from those 2 arrays. How can I make it so that the array with both random values from 2 arrays show up on my JList. I have tried everything starting with making a new array to using DeaultListModel. Any help is appreciated.

Here is my code:

public class game extends JFrame {

    private JPanel contentPane;
    private JTextField textField_1;
    private JTextField textField_2;

    //\u21BA is Skip, \u20E0 is Reverse. Action and colorName are the arrays I'm randomizing into the JList
    private String[] action = {"0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "+2",  "\u21BA", " \u20E0"};
    private Color[] color = {Color.red, Color.blue, Color.green, Color.yellow};
    private String[] colorName = {"Red", "Blue", "Green", "Yellow"};
    private DefaultListModel deck;
    /**
     * Launch the application.
     */
    public static void main (String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    game frame = new game();
                    frame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }

    /**
     * Create the frame.
     */
    public game() {
        setTitle("Uno");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(500, 500);
        contentPane = new JPanel();
        contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
        setContentPane(contentPane);
        contentPane.setLayout(new BorderLayout(0, 0));

        JTextArea textArea = new JTextArea();
        textArea.setRows(5);
        contentPane.add(textArea, BorderLayout.SOUTH);
        \\What I'm struggling with 
        deck = new DefaultListModel();
        for (int i = 0; i <= 7; i++) {
            Random r = new Random();
            deck.addElement(colorName[r.nextInt(colorName.length)] + " " + action[r.nextInt(action.length)]);
        }
        JList list = new JList(deck);
        list.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
        list.setFont(UIManager.getFont("ColorChooser.font"));
        contentPane.add(list, BorderLayout.WEST);

        JPanel panel = new JPanel();
        contentPane.add(panel, BorderLayout.EAST);
        GridBagLayout gbl_panel = new GridBagLayout();
        gbl_panel.columnWidths = new int[] {44, 0};
        gbl_panel.rowHeights = new int[]{0, 0, 0, 0, 0, 0, 0, 0, 0};
        gbl_panel.columnWeights = new double[]{1.0, Double.MIN_VALUE};
        gbl_panel.rowWeights = new double[]{0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, Double.MIN_VALUE};
        panel.setLayout(gbl_panel);

        JLabel lblNewLabel = new JLabel("Player 1 Card Amount");
        lblNewLabel.setFont(new Font("Dialog", Font.PLAIN, 12));
        GridBagConstraints gbc_lblNewLabel = new GridBagConstraints();
        gbc_lblNewLabel.insets = new Insets(0, 0, 5, 0);
        gbc_lblNewLabel.gridx = 0;
        gbc_lblNewLabel.gridy = 3;
        panel.add(lblNewLabel, gbc_lblNewLabel);

        textField_1 = new JTextField();
        textField_1.setEditable(false);
        textField_1.setFont(new Font("Dialog", Font.PLAIN, 12));
        GridBagConstraints gbc_textField_1 = new GridBagConstraints();
        gbc_textField_1.insets = new Insets(0, 0, 5, 0);
        gbc_textField_1.fill = GridBagConstraints.HORIZONTAL;
        gbc_textField_1.gridx = 0;
        gbc_textField_1.gridy = 4;
        panel.add(textField_1, gbc_textField_1);
        textField_1.setColumns(10);

        JLabel lblNewLabel_1 = new JLabel("CPU Card Amount");
        lblNewLabel_1.setFont(new Font("Dialog", Font.PLAIN, 12));
        GridBagConstraints gbc_lblNewLabel_1 = new GridBagConstraints();
        gbc_lblNewLabel_1.insets = new Insets(0, 0, 5, 0);
        gbc_lblNewLabel_1.gridx = 0;
        gbc_lblNewLabel_1.gridy = 6;
        panel.add(lblNewLabel_1, gbc_lblNewLabel_1);

        textField_2 = new JTextField();
        textField_2.setFont(new Font("Dialog", Font.PLAIN, 12));
        textField_2.setEditable(false);
        GridBagConstraints gbc_textField_2 = new GridBagConstraints();
        gbc_textField_2.fill = GridBagConstraints.HORIZONTAL;
        gbc_textField_2.gridx = 0;
        gbc_textField_2.gridy = 7;
        panel.add(textField_2, gbc_textField_2);
        textField_2.setColumns(10);
    }
