            }else{
                System.out.println("You've messed up James");
            }

            for(int i = 0; i < 3; i++){
                for(int j = 0; j < 3; j++){

            if(gamewon == false){
                if(moves == 9){
                    System.out.println("Game has been drawn! No one wins!");
                }else{
                    mod = moves % 2;
                    if(mod == 0){
                        symbol = " X ";
                    }else{
                        symbol = " O ";
                    }
                }
            }
        }while(gamewon == false || moves != 9);

        if(gamewon == true){
            if(symbol.equals(" X ")){
                System.out.println("Winner is "+play1);
            }else{
                System.out.println("Winner is "+play2);
            }
        }else{
            System.out.println("Game is drawn");
        }

    }
}

这是我之前提出的问题的进一步问题。尽管 while 循环应该在有人获胜后停止，但直到步数达到 9 为止这个游戏不会结束。 boolean 值将变为 true，但它将继续循环。

如何在保持 while 条件的情况下解决此问题，并且可能不使用中断？

Answer 1

你需要一个而不是一个或

while(gamewon == false && moves != 9);

你自己读一下，它说虽然没有赢家，而且我们还没有进入第 9 步。但是，通常更好的形式是对循环进行编码以检查您没有超出界限，而不是完全达到界限，直接测试 boolean 值也更好，因此以下内容更时尚:

while(!gamewon && moves < 9);
