java - 用 JAVA 编写井字棋游戏。使用许多 if 语句我如何让游戏读取平局游戏？

Question

提示

欢迎来玩猜谁赢的游戏! 请输入您的游戏1板(*退出)> XXOOOOXXOO
您的游戏1如下:
XXO
OOX
XOO
您的游戏 1:平局

请进入您的游戏2板(*表示退出)> XXXOOXXOO
您的游戏2如下:
XXX
OOX
XOO
您的游戏 2:X 在第 1 行赢得了游戏。

Answer 1

如果您将 if 语句转换为组合的 if else if 语句，那么 else 情况下剩下的内容将是平局。

if(winRow1('O' , ttt))
        System.out.println("Your game " + gameNum + ": O won the game by row 1");
else if(winRow2('O' , ttt))
        System.out.println("Your game " + gameNum + ": O won the game by row 2");
.
.
.
else
        System.out.println("Your game " + gameNum + ": It is a tie");

顺便说一句，这样您就可以避免出现多条消息，例如同时选中一行和一列时；)。
