Question

我的变量名称在底部附近非常愚蠢，但这不是重点。第110行说我正在做一个没有if的else语句，我几乎可以确定if是否存在。请以任何方式帮助您。

谢谢

    }


}

Answer 1

尝试删除if(chili >= 20);和else (ghost >= 20);中的分号。

Answer 2

public static boolean peppers(int chili, int ghost)
{
    boolean done;
    done = true;
    if(chili >= 20)
    {
        done = false;
        System.out.println(" YOU WIN!!!");
    }
    else if (ghost >= 20)
    {
        System.out.println(" COMPUTER WINS");

    }
    return done;
}

Answer 3

替换

else (ghost >= 20);

与

else if (ghost >= 20)

并删除if语句后的分号。
