我有一个tic tac toe游戏，它将X和O打印到JFrame中的按钮。此外，X和O也被放置在作为虚拟板的阵列中。当我在虚拟主板上调用支票获胜者时，hasWon会变为true。但在主要方法中，尚未更新。我该如何解决这个问题？我编辑了代码。现在，程序运行，最后它询问用户是否要再次播放。在那之后电路板重置，但是在我点击一次之后，再次弹出对话框，说我已经赢了。

答案 0 :(得分：0)
您正在hasWon类的主要方法
Game的新变量
public class Game extends TicTacToe
{
public static void main(String[] args)
{
//.....
//Here you are creating new method level variable with same name as `hasWon`
boolean hasWon = board.getWin();
//.....
}
public static String name1, name2;
// This variable is never updated
boolean hasWon;
}
您可能想要
Game game = new Game();
game.hasWon = board.getWin();
答案 1 :(得分：0)
更改此行：
boolean hasWon = board.getWin();
到
hasWon = board.getWin();
然后将静态添加到hasWon方法
main变量
