tictactoe實現

Question

我已經實現了對遊戲tictactoe的最簡單的解決方案，我用gui來表示它。所以我問你是否可以給我一些建議和想法，讓它更加優雅。我試圖改進的部分是TicTacToe類以及mousePressed和mouseEntered方法。這是代碼。

    public TicTacToe() 
    { 

     JPanel panel = new JPanel(new GridLayout(3,3)); 

     Border border = new LineBorder(Color.red, 2); 
     Border border2 = new LineBorder(Color.blue, 2);

Answer 1

不要使用圖標作爲狀態！使用的板適當的（數字）模式和領域的痕跡，像

int[] board = new int[3][3]; 
final static int X_MARK = 1; 
final static int O_MARK = -1; 

所以，如果玩家點擊一個字段，

1. 檢查，如果該字段爲空（相應的數組單元格的值爲0）
2. 將單元格值更改爲1或-1
3. 計算是否有贏家或抽獎（只需計算行，列和對角線的總和，如果總和爲3或-3 ，那麼我們有一個贏家，否則，如果沒有場是0，我們有一個平局）

然後，使用該模型更新板視圖。
