java:97:错误不是语句

我正在做一个井字游戏。我现在陷入了如何检查获胜者的困境。
我在我的checkwinner方法中得到“java:97:error not a statement” checkwinner应停止游戏并宣布赢家。
我的代码中的错误在哪里

您的

else if

语句缺少

if

而不是：

}else{
   (board[0][0] == playerO && board[0][1] == playerO && board[0][2] == playerO || /* första raden*/
    board[1][0] == playerO && board[1][1] == playerO && board[1][2] == playerO || /* andra raden*/
    board[2][0] == playerO && board[2][1] == playerO && board[2][2] == playerO || /* tredje raden*/
    board[0][0] == playerO && board[1][0] == playerO && board[2][0] == playerO || /*  första colum*/
    board[0][1] == playerO && board[1][1] == playerO && board[2][1] == playerO || /* andra colum*/
    board[0][2] == playerO && board[1][2] == playerO && board[2][2] == playerO || /* tredje colum*/
    board[0][0] == playerO && board[1][1] == playerO && board[2][2] == playerO || /* snea vänster till höger*/
    board[2][0] == playerO && board[1][1] == playerO && board[0][2] == playerO); /* snea höger till vänster*/
        System.out.println("Player O has won");
        gameEnd();
    }

您必须发布错误，而且您还忘记将

if

放在else部分删除

{

之后的

{

，并在大量检查之前添加

if

。将大量检查结束时的

；

替换为

{

。
