    Exclamation Help with my GUI for TicTacToe Game

    So for my university project, we are supposed to create a TicTacToe Game with GUI. I'm quite new and I've started my coding for it, but I can't seem to figure out what's wrong with my code. Everytime I run it, my 3x3 grid never displays 9 buttons. It displays anything from 1-8 but never 9 buttons! Also, sometime it doesn't display anything either Please someone help

    Driver class:
    public class GameDriver
    {
        //The main method of prompting the game
        public static void main(String[] args)
        {
            //New Noughts and Crosses game
            new BoardGUI();
        }
     
    }

    GUI:
    public class BoardGUI extends JFrame
    {
        // instance variables - replace the example below with your own
        private JFrame window;
        private JPanel controlPanel;
        private JPanel gamePanel;
        private JPanel scorePanel;
        private JPanel buttonPanel;
        private JButton[][] buttons;
        private JButton newGame;
        private JButton quit;
        private JLabel compPlayer;
        private JLabel humanPlayer;
        private JLabel humanScore;
        private JLabel compScore;
        private Container contentPane;
     
        /**
         * Constructor for objects of class BoardGUI
         */
        public BoardGUI()
        {
            // Setting the window
            JFrame window = new JFrame("Noughts And Crosses"); 
            window.setSize(500,350);
            window.setResizable(false);
            window.setDefaultCloseOperation(EXIT_ON_CLOSE);
            window.setVisible(true);
     
            // Setting the content pane
            contentPane = window.getContentPane();
            contentPane.setLayout(new BorderLayout(10,0));
     
            // Setup the game board
            gamePanel = new JPanel();
            gamePanel.setLayout(new GridLayout(3,3));
            gamePanel.setBorder(BorderFactory.createLoweredBevelBorder());
            contentPane.add(gamePanel,BorderLayout.CENTER);
     
            // Setup control panel layout
            controlPanel = new JPanel();
            controlPanel.setLayout(new BorderLayout());
            contentPane.add(controlPanel,BorderLayout.EAST);
     
            // Score panel layout setup
            scorePanel = new JPanel();
            scorePanel.setLayout(new GridLayout(2,2));
            scorePanel.setBorder(BorderFactory.createTitledBorder("Scores:"));
            controlPanel.add(scorePanel,BorderLayout.SOUTH);
     
            // Setting up the button panel
            buttonPanel = new JPanel();
            buttonPanel.setLayout(new GridLayout(2,2));
            controlPanel.add(buttonPanel,BorderLayout.NORTH);
     
            // Adding the labels for the score board
            humanPlayer = new JLabel("Player:");
            humanScore = new JLabel("  0");
            compPlayer = new JLabel("Comp:");
            compScore = new JLabel("  0");
            scorePanel.add(humanPlayer);
            scorePanel.add(humanScore);
            scorePanel.add(compPlayer);
            scorePanel.add(compScore);
     
            // Adding game button options to the button panel
            newGame = new JButton("New Game");
            quit = new JButton("Quit Game");
            buttonPanel.add(newGame);
            buttonPanel.add(quit);
     
            // Adding the buttons to the game panel
            buttons = new JButton[3][3];
            for (int row =0; row<3; row++){
                for (int col =0; col<3; col++){
                    buttons[row][col] = new JButton("");
                    gamePanel.add(buttons[row][col]);
                }
            }
     
     
     
        }
    }

    The API doc says:
    Specifying the number of columns affects the layout only when the number of rows is set to zero.
    Try setting the number of rows to 0.
    If you don't understand my answer, don't ignore it, ask a question.

    The GridLayout class's constructor takes two args: number of rows and number of columns.
    Try setting the number of rows to zero.
