用Java写一个益智编程小游戏

创建一个简单的Java益智编程小游戏，比如经典的“井字游戏”（Tic Tac Toe），可以分为以下几个步骤：

1. **设计基本框架**：

public class TicTacToe {
    private char[][] board = new char[3][3];
    private char currentPlayer;
    public TicTacToe() {
        currentPlayer = 'X'; // 初始化玩家为X
    }
}

2. **用户界面与输入处理**：

public void displayBoard() {
    for (int i = 0; i < 3; i++) {
        for (char c : board[i]) {
            System.out.print(c + " ");
        }
        System.out.println();
    }
}

public boolean makeMove(int row, int col) {
    if (board[row][col] != '\0' || !isValidMove(row, col)) return false;
    board[row][col] = currentPlayer;
    changePlayer();
    return true;
}

3. **游戏规则与胜利条件检查**：

private boolean isValidMove(int row, int col) {
    // 检查行、列和对角线是否有空格
}

private void changePlayer() {
    currentPlayer = currentPlayer == 'X' ? 'O' : 'X';
}

public boolean isGameOver() {
    // 检查是否有人获胜或所有位置已填满
}

4. **主循环与交互**：

public static void main(String[] args) {
    TicTacToe game = new TicTacToe();
    while (!game.isGameOver()) {
        game.displayBoard();
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter your move (row col):");
        int row = scanner.nextInt();
        int col = scanner.nextInt();
        if (game.makeMove(row, col)) {
            if (game.isGameOver()) {
                System.out.println("Game over!");
                break;
            }
        } else {
            System.out.println("Invalid move, try again.");
        }
    }
}
