Java中表达式的非法启动

我是Java新手。我得到一个表达式错误的非法开始。我一直在寻找答案，但无法找到，如果我使用括号不正确或没有，但我尝试了没有括号，并与他们，似乎无法通过这1错误。我需要一些帮助。 谢谢各位:

public class LIANGLAB1
{
    public static void main(String[] argv){

    gasStation A = new gasStation(3.39, 3.49);
    gasStation B = new gasStation(3.19, 3.39);

    A.sellregular(10);    A.sellregular(10);
    B.sellregular(11);    B.sellregular(12);

    if (A.moreprofit(B)) System.out.println("station A is more profitable");
   else System.out.println("station B is more profitable");

    gasStation G[] = new gasStation[10];
    for(int i=0;i<10;i++) G[i] = new gasStation(3.19,3.39);
        {gasStation highest =G[0];}

    for (int i=1;i<10;i++) 
        {if (G[i].moreprofit(highest)) highest = G[i];
            {System.out.println("highest total sales is" +highest.sales+ );}
                                                          //ERROR IS HERE
        }
    }
}

改变这个

for(int i=0;i<10;i++) G[i] = new gasStation(3.19,3.39);
    {gasStation highest =G[0];}

对此

for(int i=0;i<10;i++){
    G[i] = new gasStation(3.19,3.39);
    gasStation highest =G[0];
}

<> p>为了提高代码可读性，你应该考虑每行坚持一个语句。 编辑：

将其更改为：

for (int i=1;i<10;i++){ 
    if (G[i].moreprofit(highest))
        highest = G[i];
}
System.out.println("highest total sales is" +highest.sales);

没有理由为单个println语句打开大括号。

学习Java编码标准。你没有跟着他们。这会使您的代码难以阅读

好名字很重要。在命名类、方法和变量时多加考虑。你的目标应该是易于理解和可读

这段代码编译并运行良好

public class LIANGLAB1 {
    public static void main(String[] argv) {

        GasStation gasStationA = new GasStation(3.39, 3.49);
        GasStation gastStationB = new GasStation(3.19, 3.39);

        gasStationA.sellRegular(10);
        gasStationA.sellRegular(10);
        gastStationB.sellRegular(11);
        gastStationB.sellRegular(12);

        if (gasStationA.hasMoreProfit(gastStationB)) System.out.println("station A is more profitable");
        else System.out.println("station B is more profitable");

        GasStation arrayOfGasStations[] = new GasStation[10];
        for (int i = 0; i < 10; i++) {
            arrayOfGasStations[i] = new GasStation(3.19, 3.39);
        }

        GasStation highest = arrayOfGasStations[0];
        for (int i = 1; i < 10; i++) {
            if (arrayOfGasStations[i].hasMoreProfit(highest)) {
                highest = arrayOfGasStations[i];
            }
        }
        System.out.println("highest total sales is" + highest.sales);
    }
}

class GasStation {
    double regularprice;
    double superprice;
    double sales;

    public GasStation(double r, double s) {
        regularprice = r;
        superprice = s;
        sales = 0;
    }

    public void sellRegular(double gallons) {
        sales += regularprice * gallons;
    }

    public void sellSuper(double gallons) {
        sales += superprice * gallons;
    }

    public void gouge() {
        superprice *= 2;
        regularprice *= 2;
    }

    public boolean hasMoreProfit(GasStation other) {
        return sales > other.sales;
    }
}

最高。销售额+；}。。。删除最后一个加号。请：使用适当的缩进和换行符。它有助于可读性。拥有一个组和普遍接受的编码风格有助于可读性，不仅对你自己，尤其是对你自己！对于正在查看您的代码的其他人来说。此代码有太多错误，以至于很难知道从何处开始。自上而下都错了。这是我见过的最奇怪的括号样式。请尽量减少你的编码风格。对不起，我是个业余爱好者。
