    }

    public static void main(String[] args) {
        JFrame frame = new JFrame("五子棋");
        frame.add(new FiveChess());
        frame.setSize(X_OFFSET * 2 + GRID_SIZE * (COLS - 1), Y_OFFSET * 2 + GRID_SIZE * (ROWS - 1));
        frame.setLocationRelativeTo(null);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
    }
}

这个程序使用 Java Swing 组件库，可以在桌面上运行。如果想在网页上实现五子棋，可以使用 HTML5 和 JavaScript 技术。
