打印所有的项目 [英] Printing all the items

问题描述

有人可以帮我吗？我怎样才能打印所有我会利用的项目？ ）

pre $ public $ {
$ public $ {
$ （System.in）;
字符串选择;
String want =;
双重价格，总数= 0，付款，变更;

System.out.println（Beauty Zone Salon）;
System.out.println（欢迎客户）;
System.out.println（Hair Cut ...... 100）;
System.out.println（Manicure ...... 200）;
System.out.println（Pedicure ...... 300）;

do {
System.out.print（Enter your choice：）;
choice = input.nextLine（）;
if（choice.equalsIgnoreCase（Haircut））{
System.out.println（You choose Haircut）;
价格= 100;
total = total + price;
System.out.print（你想要做另一个服务？）;
want = input.nextLine（）;

} else if（choice.equalsIgnoreCase（Manicure））{
System.out.println（You choose Manicure）;
价格= 200;
total = total + price;
System.out.print（你想要做另一个服务？）;
want = input.nextLine（）; （Pedicure））{
System.out.println（您选择Pedicure）;

} else if（choice.equalsIgnoreCase（Pedicure））
价格= 300;
total = total + price;
System.out.print（你想要做另一个服务？）;
want = input.nextLine（）;
}
} while（want.equalsIgnoreCase（Y））;
System.out.println（ITEMS \\\
）;
System.out.println（总计到期日+总计）;
System.out.print（输入您的付款金额：）;
payment = input.nextDouble（）;
change =付款 - 总计;

System.out.println（您的更改是：+更改）;
System.out.println（Goodbye）;

解决方案

如果您不知道数组，但是可以在循环完成之后构建要打印的所有项目。在开始时：

 字符串items_ordered =; 
  

然后对于每次购买，当您通过循环时，添加到字符串：

  items_ordered + =理发... 100 \\\

  

最后打印字符串

  System.out.println（items_ordered） ; 
  

我想这就是你要求的...

Can someone please help me? How can I print all the items I will avail? Thank you in advance :)

public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        String choice;
        String want = "";
        double price, total = 0, payment, change;

        System.out.println("Beauty Zone Salon");
        System.out.println("Welcome Customer");
        System.out.println("Hair Cut......100");
        System.out.println("Manicure......200");
        System.out.println("Pedicure......300");

        do {
            System.out.print("Enter your choice: ");
            choice = input.nextLine();
            if (choice.equalsIgnoreCase("Haircut")) {
                System.out.println("You choose Haircut");
                price = 100;
                total = total + price;
                System.out.print("Do you want to do another service?");
                want = input.nextLine();

            } else if (choice.equalsIgnoreCase("Manicure")) {
                System.out.println("You choose Manicure");
                price = 200;
                total = total + price;
                System.out.print("Do you want to do another service?");
                want = input.nextLine();

            } else if (choice.equalsIgnoreCase("Pedicure")) {
                System.out.println("You choose Pedicure");
                price = 300;
                total = total + price;
                System.out.print("Do you want to do another service?");
                want = input.nextLine();
            }
        } while (want.equalsIgnoreCase("Y"));
        System.out.println("ITEMS\n");
        System.out.println("Your total due is " + total);
        System.out.print("Enter amount of your payment:");
        payment = input.nextDouble();
        change = payment - total;

        System.out.println("Your change is: " + change);
        System.out.println("Goodbye");
    }

解决方案

If you don't know arrays yet, you can build up all the items in a string to be printed after the loop completes. At the beginning:

String items_ordered="";

Then for each purchase, when you go through the loop, add to the string:

items_ordered+="Haircut... 100\n"

At the end, print the string

System.out.println(items_ordered); 

I think this is what you are asking...
