这种 MVC 方法是编写数独游戏的好方法吗？
Is this MVC method a good way to program a Sudoku Game?
我正在制作数独游戏。我来这里是为了寻求帮助，因为我完全被困在我的代码中了。我不是要你完成我的代码，我知道那不是你的工作。只需提示下一步该怎么做就很棒！
我使用 MVC 和 Swing Components for GUI 来简化代码。我对每个领域和方法进行了划分，以便了解下一步该做什么，但我很困惑。我特别难以理解如何执行以下方法：
初始化网格
选择游戏难度
makeMove
取消移动
型号
public class GameSudokuModel {
// states -- fields
Scanner userInput = new Scanner (System.in); // accept user input
// int levelDifficulty = 0; // level of difficulties
int [] gridSize ; // Sudoku 9x9 == 81 cells -- used to initialize grid or solve puzzle --
int [] subGridSize ; // a sub-grid = 9 cells
int gameMove = 0; // calculate the total number of moves per game // ++makeMove and --cancelMove
int [] gameCell = {1, 2, 3, 4, 5, 6, 7, 8, 9}; // a cell contain a list of choices numbers 1-9
int currentGameTime = 0; // calculates the total time to complete a puzzle
String currentPlayerName = userInput.nextLine(); // player name
// end of fields
//behaviors -- methods

initializeGrid 和 chooseGameDifficulty 并不是模型的真正特征。该模型维护数据的当前状态，并使用规则来管理它。
从技术上讲，这些功能应该是某种工厂的功能，给定难度级别将 return 模型的实例
public class SudokuFactory {
public enum Difficulty {
HARD,
MODERATE,
EASY
}
public SudokuModel createModel(Difficulty difficult) {
// Make a new model based on the rules for your difficulty
// settings
}
}
模型将只包含管理它的信息和功能
你也应该在实际可行的情况下避免static，它不应该被用作交叉class通信机制，如果你需要共享数据，你应该通过它。 static 只会让整个事情更难管理和调试
视图将从用户那里获取信息（如难度级别），控制器将使用这些信息来构建新模型。然后该模型将被传递给一个新的控制器，该控制器将生成一个新视图，该视图应显示模型的当前状态。
然后控制器将响应视图中的更改，更新模型，控制器将响应模型中的更改并更新视图。
您也应该更喜欢使用 interfaces over implementation
因此，根据我对数独的（相当可悲的）理解，您可以使用像 ...
这样简单的模型
public interface SudokuModel {
public void setValueAt(int value, int row, int col) throws IllegalArgumentException;
public int getValueAt(int row, int col);
}
现在，就我个人而言，我有一个具有两个缓冲区的实现，一个代表实际 game/solution，另一个代表玩家数据（pre-filled 基于难度级别), 现在您可以拥有一个缓冲区，但是您需要不断扫描网格以查看新值是否有效而我太懒了 ;)
