Question

我们已经被指派在我的课堂上用Java制作一个原始的购物车，除了夏威夷的销售税之外，我已经设法完成了所有的工作，而这些税只是拒绝正常工作。如果有人能够指出我做错了什么，我真的很感激，因为我问的每个人都不知道问题是什么。

    double IceCreamVanillaPrice = 2.50;
    double IceCreamCCPrice = 4.50;
    double IceCreamOSPrice = 3.25;
    double IceCreamBCPrice = 5.00;


    Scanner getInput = new Scanner(System.in);

    // Setting up the menu
    System.out.println("Hello! Welcome to Neal's Ice Cream Kitchen.");
    System.out.println("What would you like?");
    System.out.println("-----------------------------------------------
    -------");
    System.out.println("(1) Vanilla Ice Cream            $"+ 
    IceCreamVanillaPrice);
    System.out.println("(2) Cookies and Cream Ice Cream  $"+ 
    IceCreamCCPrice);
    System.out.println("(3) Orange Sherbet Ice Cream     $"+ 
    IceCreamOSPrice);
    System.out.println("(4) Berry and Cherry Ice Cream   $"+ 
    IceCreamBCPrice);
    System.out.println("-----------------------------------------------
     -------");
    System.out.println("Enter the number of the Ice Cream you want to 
    order.");



    // Setting up the ordering system and how much they want as well as 
     figuring out the total cost 
    int numIceCream = 0;
    numIceCream = getInput.nextInt();


    // Vanilla Ice Cream

    if (numIceCream == 1) {

       System.out.println("How much Vanilla Ice Cream cones do you 
       want?");
       int numVanilla = getInput.nextInt();
       double SalesTax1 = numVanilla * IceCreamVanillaPrice + 0.04167 ;
       System.out.println("Your total will be $" + SalesTax1); }


      // Cookies and Cream Ice Cream

      else if (numIceCream == 2) {

        System.out.println("How much Cookies and Cream Ice Cream cones 
        do you want?");
        int numCC = getInput.nextInt();
        double SalesTax2 = numCC * IceCreamCCPrice + 0.04167 ;
        System.out.println("Your total will be $" + SalesTax2); }


      // Orange Sherbet Ice Cream

      else if (numIceCream == 3) { 

        System.out.println("How much Orange Sherbert Ice Cream cones do 
         you want?");
        int numOS = getInput.nextInt();
        double SalesTax3 = numOS * IceCreamOSPrice + 0.04167 ;
        System.out.println("Your total will be $" + SalesTax3); }


      // Berry and Cherry Ice Cream

      else if (numIceCream == 4) {

        System.out.println("How much Berry and Cherry Ice Cream cones 
        do you want?");
        int numBC = getInput.nextInt();
        double SalesTax4 = numBC * IceCreamBCPrice + 0.04167 ;
        System.out.println("Your total will be $" + SalesTax4); }

    else {

      System.out.println ("Sorry that is not a Valid Order"); }





   System.out.println("Thank you for shopping at Neal's Ice Cream 
   Kitchen! Have a Nice day!");

Answer 1

看起来你要为每个订单增加4.167美分....你可能想要将每个订单乘以1.04167，如果你正在计算税款。

double SalesTax4 = numBC * IceCreamBCPrice * 1.04167;

Answer 2

我认为您需要重新审视您的纳税计算声明。它应该是这样的：salestax = numIC * ICPrice * 1.04167; 如果4.167％是固定的ST费率。

Java程序无法正确计算销售税
