Swing是Java提供的图形用户界面(GUI)工具包，可以用来实现窗口、按钮、标签等GUI组件。下面是一个简单的五子棋小游戏的设计与实现：

1. 设计五子棋游戏棋盘

我们可以使用JPanel来实现游戏棋盘，可以通过设置背景颜色、绘制线条等方式来美化游戏棋盘。下面是一个简单的实现：

public class ChessBoard extends JPanel {
    private int[][] board; // 存储棋盘状态
    private int currentPlayer; // 当前落子方
    private boolean isGameOver; // 游戏是否结束

    public ChessBoard() {
        board = new int[15][15];
        currentPlayer = 1;
        isGameOver = false;
        setPreferredSize(new Dimension(500, 500));
        addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent e) {
                if (isGameOver) {
                    return;
                }
                int row = e.getY() / 33;
                int col = e.getX() / 33;
                if (row >= 0 && row < 15 && col >= 0 && col < 15 && board[row][col] == 0) {
                    board[row][col] = currentPlayer;
                    if (checkWin(row, col)) {
                        JOptionPane.showMessageDialog(null, "Player " + currentPlayer + " wins!");
                        isGameOver = true;
                    } else {
                        currentPlayer = 3 - currentPlayer;
                    }
                    repaint();
                }
            }
        });
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        for (int i = 0; i < 15; i++) {
            g.drawLine(0, i * 33, 495, i * 33);
            g.drawLine(i * 33, 0, i * 33, 495);
        }
        for (int i = 0; i < 15; i++) {
            for (int j = 0; j < 15; j++) {
                if (board[i][j] == 1) {
                    g.setColor(Color.BLACK);
                    g.fillOval(j * 33 - 15, i * 33 - 15, 30, 30);
                } else if (board[i][j] == 2) {
                    g.setColor(Color.WHITE);
                    g.fillOval(j * 33 - 15, i * 33 - 15, 30, 30);
                }
            }
        }
    }

    private boolean checkWin(int row, int col) {
        int count = 1;
        int i, j;
        i = row - 1;
        j = col;
        while (i >= 0 && board[i][j] == currentPlayer) {
            count++;
            i--;
        }
        i = row + 1;
        j = col;
        while (i < 15 && board[i][j] == currentPlayer) {
            count++;
            i++;
        }
        if (count >= 5) {
            return true;
        }
        count = 1;
        i = row;
        j = col - 1;
        while (j >= 0 && board[i][j] == currentPlayer) {
            count++;
            j--;
        }
        i = row;
        j = col + 1;
        while (j < 15 && board[i][j] == currentPlayer) {
            count++;
            j++;
        }
        if (count >= 5) {
            return true;
        }
        count = 1;
        i = row - 1;
        j = col - 1;
        while (i >= 0 && j >= 0 && board[i][j] == currentPlayer) {
            count++;
            i--;
            j--;
        }
        i = row + 1;
        j = col + 1;
        while (i < 15 && j < 15 && board[i][j] == currentPlayer) {
            count++;
            i++;
            j++;
        }
        if (count >= 5) {
            return true;
        }
        count = 1;
        i = row - 1;
        j = col + 1;
        while (i >= 0 && j < 15 && board[i][j] == currentPlayer) {
            count++;
            i--;
            j++;
        }
        i = row + 1;
        j = col - 1;
        while (i < 15 && j >= 0 && board[i][j] == currentPlayer) {
            count++;
            i++;
            j--;
        }
        if (count >= 5) {
            return true;
        }
        return false;
    }
}

2. 首页菜单要求具备重新开始、悔棋、退出功能

我们可以使用JMenuBar和JMenu来实现菜单栏，通过添加JMenuItem来实现每个菜单项的功能。下面是一个简单的实现：

public class FiveChessGame extends JFrame {
    private ChessBoard chessBoard;

    public FiveChessGame() {
        setTitle("Five Chess Game");
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setResizable(false);
        chessBoard = new ChessBoard();
        setContentPane(chessBoard);
        JMenuBar menuBar = new JMenuBar();
        JMenu gameMenu = new JMenu("Game");
        JMenuItem restartItem = new JMenuItem("Restart");
        restartItem.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                chessBoard = new ChessBoard();
                setContentPane(chessBoard);
                pack();
                setLocationRelativeTo(null);
            }
        });
        gameMenu.add(restartItem);
        JMenuItem undoItem = new JMenuItem("Undo");
        undoItem.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                chessBoard.undo();
            }
        });
        gameMenu.add(undoItem);
        JMenuItem exitItem = new JMenuItem("Exit");
        exitItem.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                System.exit(0);
            }
        });
        gameMenu.add(exitItem);
        menuBar.add(gameMenu);
        JMenu helpMenu = new JMenu("Help");
        JMenuItem ruleItem = new JMenuItem("Rule");
        ruleItem.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                JOptionPane.showMessageDialog(null, "The rule of five chess game is to connect five pieces vertically, horizontally or diagonally.");
            }
        });
        helpMenu.add(ruleItem);
        menuBar.add(helpMenu);
        setJMenuBar(menuBar);
        pack();
        setLocationRelativeTo(null);
        setVisible(true);
    }

    public static void main(String[] args) {
        new FiveChessGame();
    }
}

3. 游戏要求具备人人、人机模式

我们可以通过添加一个JRadioButton来实现人人和人机模式的选择。对于人机模式，我们可以使用简单的随机算法来实现电脑的落子。下面是一个简单的实现：

public class ChessBoard extends JPanel {
    private int[][] board; // 存储棋盘状态
    private int currentPlayer; // 当前落子方
    private boolean isGameOver; // 游戏是否结束
    private boolean isAI; // 是否为AI模式

    public ChessBoard() {
        board = new int[15][15];
        currentPlayer = 1;
        isGameOver = false;
        isAI = false;
        setPreferredSize(new Dimension(500, 500));
        addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent e) {
                if (isGameOver) {
                    return;
                }
                int row = e.getY() / 33;
                int col = e.getX() / 33;
                if (row >= 0 && row < 15 && col >= 0 && col < 15 && board[row][col] == 0) {
                    board[row][col] = currentPlayer;
                    if (checkWin(row, col)) {
                        JOptionPane.showMessageDialog(null, "Player " + currentPlayer + " wins!");
                        isGameOver = true;
                    } else {
                        currentPlayer = 3 - currentPlayer;
                        if (isAI) {
                            aiPlay();
                        }
                    }
                    repaint();
                }
            }
        });
    }

    public void setAI(boolean isAI) {
        this.isAI = isAI;
    }

    private void aiPlay() {
        Random random = new Random();
        int row, col;
        do {
            row = random.nextInt(15);
            col = random.nextInt(15);
        } while (board[row][col] != 0);
        board[row][col] = currentPlayer;
        if (checkWin(row, col)) {
            JOptionPane.showMessageDialog(null, "Player " + currentPlayer + " wins!");
            isGameOver = true;
        } else {
            currentPlayer = 3 - currentPlayer;
        }
        repaint();
    }
}

4. 提供帮助菜单说明游戏规则

我们可以使用JOptionPane来实现游戏规则的提示。下面是一个简单的实现：

public class FiveChessGame extends JFrame {
    private ChessBoard chessBoard;

    public FiveChessGame() {
        setTitle("Five Chess Game");
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setResizable(false);
        chessBoard = new ChessBoard();
        setContentPane(chessBoard);
        JMenuBar menuBar = new JMenuBar();
        JMenu gameMenu = new JMenu("Game");
        JMenuItem restartItem = new JMenuItem("Restart");
        restartItem.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                chessBoard = new ChessBoard();
                setContentPane(chessBoard);
                pack();
                setLocationRelativeTo(null);
            }
        });
        gameMenu.add(restartItem);
        JMenuItem undoItem = new JMenuItem("Undo");
        undoItem.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                chessBoard.undo();
            }
        });
        gameMenu.add(undoItem);
        JMenuItem exitItem = new JMenuItem("Exit");
        exitItem.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                System.exit(0);
            }
        });
        gameMenu.add(exitItem);
        menuBar.add(gameMenu);
        JMenu helpMenu = new JMenu("Help");
        JMenuItem ruleItem = new JMenuItem("Rule");
        ruleItem.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                JOptionPane.showMessageDialog(null, "The rule of five chess game is to connect five pieces vertically, horizontally or diagonally.");
            }
        });
        helpMenu.add(ruleItem);
        menuBar.add(helpMenu);
        JMenu modeMenu = new JMenu("Mode");
        JRadioButtonMenuItem playerItem = new JRadioButtonMenuItem("Player vs. Player");
        playerItem.setSelected(true);
        playerItem.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                chessBoard.setAI(false);
            }
        });
        modeMenu.add(playerItem);
        JRadioButtonMenuItem aiItem = new JRadioButtonMenuItem("Player vs. AI");
        aiItem.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                chessBoard.setAI(true);
            }
        });
        modeMenu.add(aiItem);
        ButtonGroup group = new ButtonGroup();
        group.add(playerItem);
        group.add(aiItem);
        menuBar.add(modeMenu);
        setJMenuBar(menuBar);
        pack();
        setLocationRelativeTo(null);
        setVisible(true);
    }

    public static void main(String[] args) {
        new FiveChessGame();
    }
}

以上就是一个简单的五子棋小游戏的设计与实现，希望能对您有所帮助！
