我正在制作Tic Tac Toe游戏。我现在坚持如何检查胜利者 我的checkwinner方法得到“java：97：error not a statement” checkwinner应该停止比赛并宣布获胜者 我的代码中的错误在哪里？
import java.util.Scanner;

private static char [][] board = new char [3][3];

private static char playerO = 'O';
private static Scanner keyboard = new Scanner(System.in);

private static boolean playerTurn = true;
public static void main(String[] args){
runing();
}
public static void runing(){
showBoard();
currentPlayer();
gameEnd ();
}
public void menu(){
System.out.println("welcome to TIC TAC TOE ");
System.out.println("would you like to play? (Y/N)");
}

System.out.print( "[ " + board[i][j] + " ]" + "\t");
}
System.out.println("\n");

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();
}
尝试：
} else if(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();
