                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);

        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");
        }

    }
}

一旦游戏运行并且有人赢了，即使布尔变量gamewon为真，它也不会停止循环，这应该会停止while循环。

如果这个运行正常并与你一起工作可能是我的日食，如果没有那么请告诉我什么是错的。 JimiiBee

Answer 1

if(moves == 9){
    System.out.println("Game has been drawn! No one wins!");
}

应该是：

if(moves == 9){
    System.out.println("Game has been drawn! No one wins!");
    break;
}

Noughts和Crosses检查是否有人赢了
