Question

Kann mir bitte jemand helfen? Wie kann ich alle Artikel drucken, die ich nutzen werde? Vielen Dank im Voraus :)

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"); 
    } 

Answer 1

Wenn Sie nicht wissen, Arrays noch, können Sie alle Elemente in einem String aufbauen zu gedruckt werden, nachdem die Schleife abgeschlossen ist. Zu Beginn:

String items_ordered=""; 

Dann für jeden Kauf, wenn Sie durch die Schleife gehen, fügen Sie die Zeichenfolge:

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

Am Ende, drucken Sie die Zeichenfolge

System.out.println(items_ordered); 

I denke, das ist, was Sie fragen ...

Ich denke, das kann Ihnen helfen

public static void main(String[] args) { 
     Scanner input = new Scanner(System.in); 
     String choice; 
     String want = ""; 
     double price, total = 0, payment, change; 
      List<String> totalItems = new ArrayList<>();  
     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; 
          totalItems.add("Harcut"); 
       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; 
          totalItems.add("Manicure"); 
       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; 
          totalItems.add("Preducure"); 
       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"); 

      System.out.println("Total Items:"); 
      for(String item: totalItems){ 
       System.out.println(item); 
      } 
    }

Und hier ist noch eine weitere Möglichkeit:

Scanner input = new Scanner (System.in); 

// Pick a Service by way of Service Number entry 
// rather than entering the service name. 
System.out.println("Beauty Zone Salon"); 
System.out.println("Welcome Customer"); 
System.out.println("1) Hair Cut......$100.00"); 
System.out.println("2) Manicure......$200.00"); 
System.out.println("3) Pedicure......$300.00"); 

String want = "";  // String variable to hold the 'Do You Want More Service' answer. 
String items = "";  // String variable to hold delimited items selected. 
int choice = 0;   // Integer varaible to hold the service selected. 
double total = 0.0;  // Double variable to hold the total cost of all selected services. 
double payment = 0.0; // Double variable to hold the payment supplied. 
double change = 0.0; // Double variable to hold the monetary amount to be returned to customer. 
while (want.equalsIgnoreCase("y") || want.equals("")) { 
    System.out.print("\nEnter your choice (1 to 3 - 0 to cancel): "); 
    choice = input.nextInt(); 
    input.nextLine(); // Handle the \r\n which isn't handled by Scanner.nextInt() 
    // If 0 is supplied then User wants to cancel all. 
    if (choice == 0) { break; } 

    // Hair Cut selected... 
    if(choice == 1){ 
     // Make sure Hair Cut hasn't already been selected. 
     if (items.contains("Hair Cut")) { 
      System.out.println("You have already selected a Hair Cut!"); 
      continue; 
     } 
     System.out.println("You choose Hair Cut (cost $100.00)"); 
     if (items.equals("")) { items+= "Hair Cut ($100.00)"; } 
     else { items+= ";Hair Cut ($100.00)"; } 
     total+= 100.00; 
    } 
    // Manicure selected... 
    else if(choice == 2){ 
     // Make sure Manicure hasn't already been selected. 
     if (items.contains("Manicure")) { 
      System.out.println("You have already selected a Manicure!"); 
      continue; 
     } 
     System.out.println("You choose Manicure (cost $200.00)"); 
     if (items.equals("")) { items+= "Manicure ($200.00)"; } 
     else { items+= ";Manicure ($200.00)"; } 
     total+= 200.00; 
    } 
    // Pedicure selected... 
    else if(choice == 3){ 
     // Make sure Pedicure hasn't already been selected. 
     if (items.contains("Pedicure")) { 
      System.out.println("You have already selected a Pedicure!"); 
      continue; 
     } 
     System.out.println("You choose Pedicure (cost $300.00)"); 
     if (items.equals("")) { items+= "Pedicure ($300.00)"; } 
     else { items+= ";Pedicure ($300.00)"; } 
     total+= 300.00; 
    } 

    // If all items in the list have been selected by the 
    // customer then jump out and provide the total due. 
    if (items.split(";").length == 3) { break; } 
    want = ""; 
    while (want.equals("") || (!want.equalsIgnoreCase("y") && !want.equalsIgnoreCase("n"))) { 
     System.out.print("\nDo you want to do another service? (y/n)"); 
     want = input.nextLine(); 
    } 
} 
if (!items.equals("")) { 
    System.out.println("\n=============================="); 
    System.out.println("ITEMS SELECTED:"); 
    String[] selectedItems = items.split(";"); 
    for (int i = 0; i < selectedItems.length; i++) { 
     System.out.println(selectedItems[i]); 
    } 
    System.out.println("Your total due is: $"+total); 
    System.out.println("------------------------------"); 

    while (payment < total) { 
     System.out.print("\nEnter amount of your payment (0 to cancel):"); 
     payment=input.nextDouble(); input.nextLine(); 
     if (payment == 0) { break; } 
     if (payment < total) { 
      System.out.print("Payment must be $" + total + " or more."); 
     } 
    } 
    if (payment != 0) { 
     change = payment - total; 
     System.out.println("Change back from your $" + payment + " payment is: $" + change); 
      } 
    else { System.out.println("SERVICE CANCELED!"); } 
} 
else { System.out.println("SERVICE CANCELED!"); } 

System.out.println("\nThank you for your business, Goodbye");
