Question

我正在完成这个java程序和错误消息＆＃34;在＆＃34; void＆＃34;之前或之前期待类或接口声明＆＃34;很难解决。这令人困惑，因为我有相同的＆＃34; public static void＆＃34;之前设置两个电话。我不这么认为，因为电话不在主要方法之内。我错过了什么？我的工作如下。

    import java.util.Scanner; //needed for input

    public class Holidaycharitydonations {
    static double[] cashDonations = new double[6];

    static double[] lbsFood = new double[6]; 

    static String[] siteName = new String[6]; 
    static String bestSiteCash = " "; 

    static String bestSiteFood = " "; 

    static double totalCash = 0; 

    static double totalFood = 0; 

    static double maxFood = 0; 
    static double maxCash = 0; 

    public static void main(String[] args) {

    Scanner input = new Scanner(System.in); 
    String runAgain = "yes"; //use runAgain

    do {

     getDonations();
     processDonations();
     displayDonations();


     System.out.print("Enter yes if you want to run again: ");
     runAgain = input.next();
     input.nextLine(); 
     System.out.print("\n\n\n");
      } while (runAgain.equalsIgnoreCase("yes"));

      } // end of main

    public static void getDonations() {
    Scanner input = new Scanner(System.in); 

   for (int i = 0; i < 6; i++) {
     System.out.println("Enter site " + (i + 1) + " name: ");
     siteName[i] = input.next();
     input.nextLine();//fixes skipping issue

     System.out.println("Enter cash donation(USD) for" + siteName[i] + ":   ");
     cashDonations[i] = input.nextDouble();
     while (cashDonations[i] < 1 )
     {
        System.out.println("SORRY - must be greater than 1 USD");
        System.out.print("Enter cash donation(USD) for " + siteName[i] + ": ");
        cashDonations[i] = input.nextDouble();
     }
     System.out.println("Enter food donation(lbs.) for " + siteName[i] + ": ");
     lbsFood[i] = input.nextDouble();

     while (lbsFood[i] < 1)
     {
        System.out.println("SORRY - must be greater than 1lb");
        System.out.println("Enter food donation(lbs.) for " + siteName[i] + ": ");
        lbsFood[i] = input.nextDouble();
     }

        }

}

    public static void processDonations() {
    totalCash = 0;
    totalFood = 0;
    maxCash = cashDonations[0];
    maxFood = lbsFood[0];
    for (int i = 1; i < 6; i++)
    {
     if (cashDonations[i] > maxCash)
     {
        maxCash = cashDonations[i];
        bestSiteCash = siteName[i];
     } 
     if (lbsFood[i] > maxFood)
     {
        maxFood = lbsFood[i];
        bestSiteFood = siteName[i];
     } 
     }//End of for loop


     for (int i = 0; i < 6; i++)

     totalCash = totalCash + cashDonations[i];
     totalFood = totalFood + lbsFood[i];
     }
     }//end of processDonations


     public static void displayDonations() {

     System.out.println("\n\n\n");
     System.out.println("\tHOLIDAY DONATION LOCATIONS REPORT\t");
     System.out.println("\t---------------------------------\t");
     System.out.println("\n\n\n");


    for (int i = 0; i < 6; i++)
    {
   System.out.print("Site:" + siteName[i]); 
   System.out.print("Individual Cash Donations: $" + cashDonations[i]);
   System.out.print("Individual Food Donations:" + lbsFood[i]+ "lbs" );
   System.out.print("\n");

   }//End of for loop

   System.out.print("\tHoliday Donation Totals Report\t");
   System.out.println("\t----------------------------\t");

   System.out.println("Total Cash Donations are $" + totalCash );
   System.out.println("Total Food Donations are " + totalFood + "lbs" );
   System.out.println("\n");
   System.out.println("\tHoliday Donation Best Site Report\t");
   System.out.println("\t---------------------------------\t");  

   System.out.println("\n");
   System.out.println("Best location site for cash donation:" + bestSiteCash );
   System.out.println("Max cash collected was:" + maxCash );

   System.out.println("\n");
   System.out.println("Best location site for food donation:" + bestSiteFood );
   System.out.println("Max food collected was:" + maxFood );
   }// end of displayDonations()


   }// end of class

在这里，你在循环声明之后错过了{

    ... 
    for (int i = 0; i < 6; i++)
        totalCash = totalCash + cashDonations[i];
        totalFood = totalFood + lbsFood[i];
    } 
}//end of processDonations

应该是

    ... 
    for (int i = 0; i < 6; i++) {
        totalCash = totalCash + cashDonations[i];
        totalFood = totalFood + lbsFood[i];
    } 
}//end of processDonations

＆＃34;期待或之前的等级或界面声明＆＃34; void＆＃34; ＆＃34;
