Answer 1

if (currentstate == you_win){
        System.out.println("'X' Won!!");
        else if (currentstate == comp_win)
            System.out.println("'O' won!!");
            else if (currentstate == draw)
            System.out.println("It's a Draw :(");
    }

看看这一行（我删除了一些无关的代码，以便更容易看到）：

    if (currentstate == you_win){
        else if (currentstate == comp_win)
            //...
    }

以这种方式看，你能看出为什么这是不正确的吗？顺便说一句，这就是您应该始终使用{和}的原因。请改为if ... else：

if (currentstate == you_win){
      // ...
 }
 else if (currentstate == comp_win) {
     // ...
  }
    //...

或者，更好的是，只需使用switch声明：

switch (currentstate) {
       case you_win:
             System.out.println("'X' Won!!");
             break;
        case comp_win:
            System.out.println("'O' won!!");
            break;

        case draw:
            System.out.println("It's a Draw :(");
            break;
}

我的其他if语句不适用于我的tic tac toe程序
