java - 我不断收到编译器错误，说 Rainfallmain.java :13: error: expected.

Question

我不知道为什么，编译器错误指向字符串数组。我应该创建一个 for 循环并手动用一年中月份的名称填充每个下标吗？请帮忙!!

import java.util.*;

public class Rainfallmain
{
public static void main(String [] args)
{
    double months = 12;
  double average = Rainfallyr.getAverage();
  double Mostrain = Rainfallyr.getHighest();
  double Leastrain = Rainfallyr.getLowest();
  double total = Rainfallyr.getTotal();
    double [] Rainfallyr =  new Rainfall[months];
  String[] Mon = {"January", "Febuary", "March", "April", "May", "June", "July", "August". "September", "October", "November", "December"};

     getRainvalues(Rainfallyr, mon);

  System.out.println(" The total rainfall for the year is "  + Mostrain);
  System.out.println(" The total least aount of rain is "  + Leastrain);
  System.out.println(" The total rainfall for the year is "  + total);
  System.out.println(" The average rainfall for the year is "  + average);


}


}
    public static void getAllvalues(double []rain, String [] mon)
    {
        Scanner input = new Scanner(System.in);
      for(int i = 0; i < r.length; i++)
      {
        System.out.print(" Enter Rain for each month" +mon[i]+" :");
        r[i] = input.nextDouble();


      }




    }

Answer 1

"August". "September"

成员访问运算符 . 后面需要跟一个标识符(正在访问的成员的名称)，而不是字符串文字。这就是为什么错误消息显示“需要标识符”。

您可能想在那里使用逗号。
