hi all i have code main and tictactoe class
here my example
of main class. in this code i input something like string number
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                Scanner scanner = new Scanner(System.in);
                System.out.println("Enter number of ROW Column Do you want to use");
                String input = scanner.next();
                Integer Input = Integer.parseInt(input);
                new TTTGraphics2P(Input); // Let the constructor do the job
            }
        });
and this is for my class of tictactoe program. if i run this code i only have 3x3 tictactoe program, so i want to modify one of code using my input so my tictactoe will be Input x input
