令牌“关闭”上的语法错误，此令牌后应有标识符

Question

I was working on a simple program and the same problem would keep coming up. It underlines the word close in input.close(); and I'd search through my program to try and find any errors but to no avail. Here's my code:

import java.util.Scanner;

    public static void main(String[] args)
    {
        Scanner input = new Scanner(System.in);

        String runProgram = ""; 
        String itemDesc = "";
        char cookieType = ' ';
        char shirtType = ' ';
        char itemChoice = ' ';
        char sizeChoice = ' ';
        double itemPrice = 0.0;
        double totalSales = 0.0;
        int totalSigned = 0;
        int totalLemonade = 0;
        int totalChocChip = 0;
        int totalOatmeal = 0;
        int totalRegShirt = 0;
        int totalTrans = 0;

        //Prime read of item selection
        itemChoice = getMenuSelection(input);
        while (itemChoice != 'Q')
        {
            if (itemChoice == 'L')
            {
                sizeChoice = getCupSize(input);
            }
            else if (itemChoice == 'C') 
            {
                cookieType = getCookieType(input);
            }
            else
            {
                shirtType = getShirtType(input);
            }

            //displayResults(i
                System.out.print("Great, your order is as follows: ");
                System.out.print("Item Purchased " + itemDesc);
                System.out.print("Item Price $" + itemPrice);
                System.out.print("  ");
                totalTrans = totalTrans + 1;
                totalSales = totalSales + itemPrice;
            itemChoice = getMenuSelection(input);
        }   //END WHILE

        System.out.printf("\n%-30s%30s\n", "Total Number of Transactions", totalTrans);
        System.out.printf("\n%-30s%30s\n", "ITEM DESCRIPTION", "QUANTITY SOLD");
        System.out.printf("%-30s%23s%s\n", "Lemonade", totalLemonade, " ounces");
        System.out.printf("%-30s%30s\n", "Chocolate Chip Cookies", totalChocChip);
        System.out.printf("%-30s%30s\n", "Oatmeal Cookies", totalOatmeal);
        System.out.printf("%-30s%30s\n", "Plain Shirts", totalRegShirt);

        System.out.printf("\n%-30s%25s%.2f\n\n", "TOTAL SALES", "$", totalSales);

        //displayResults(totalSales, totalSigned, totalLemonade, totalChocChip, totalOatmeal, totalRegShirt, totalTrans);

Thanks for the help in advance!

Answer 1

Your

input.close();

at the end of the class is not in a method, this is not allowed in Java.

You need to move this to your main method. It should probably go after the end of your while loop as you have finished with input at that point:

   }   //END WHILE

   input.close();

   System.out.printf("\n%-30s%30s\n", "Total Number of Transactions", totalTrans);

Once you have done this you will find there are other compile errors which Eclipse can only detect when you have fixed the first error.
