我正在建立一个数独游戏。我来这里是为了得到一些帮助，因为我完全陷入了我的代码中。我没有要求你完成我的代码，我知道这不是你的工作。只有几个提示，下一步该做什么会很棒！
我使用GUI的MVC和Swing组件来使代码更轻松。我划分了每个领域和方法，所以我可以理解接下来要做什么，但我很困惑。我特别难以理解如何执行以下方法：
initializeGrid
chooseGameDifficulty
makeMove
cancelMove
模型
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

答案 0 :(得分：3)
initializeGrid和chooseGameDifficulty并非真正的模型功能。该模型维护数据的当前状态，规则用于管理数据。
从技术上讲，这些功能应该是某种工厂的功能，给出一个难度级别会返回模型的实例
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
}
}
该模型将只包含管理它的信息和功能
你应该尽可能避免static，它绝不应该用作跨类通信机制，如果你需要共享数据，你应该通过它。 static只会让整个事情变得更难以管理和调试
视图将从用户获取信息（如难度级别），控制器将使用该信息来构建新模型。然后将模型传递给新的控制器，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。
您还应该更喜欢使用interfaces over implementation
所以，根据我对Sudoku的理解（相当可怜）你可以使用一个简单的模型......
public interface SudokuModel {
public void setValueAt(int value, int row, int col) throws IllegalArgumentException;
public int getValueAt(int row, int col);
}
现在，我个人而言，我有一个实现有两个缓冲区，一个代表实际的游戏/解决方案，一个代表玩家数据（根据难度级别预先填充），现在你可以拥有一个缓冲区，但你不断扫描网格，看看新值是否有效，我只是太懒了;）
