Ok, here is the code that I've been working on all day. Again, please remember I've only been doing Java for 3 weeks so I'm stumbling through some things. The code I posted earlier was my pre-Arrays attempts. The program still compiles and runs correctly but I still can't get it to advance when you choose "n" for another quote so I can't see if the information has been collected by the array. Or if what I'm even saying makes sense.

import java.text.NumberFormat;
import java.util.ArrayList;
import java.util.Scanner;

public class NewClass {

     public static void main(String[] args)
    {
        ArrayList<String> code =  new ArrayList<>();
        
        // display a welcome message
        System.out.println("Welcome to the High Octane Quote Calculator");
        System.out.println();

        // perform 1 or more calculations
        Scanner sc = new Scanner(System.in);
        String choice = "y";
        while (choice.equalsIgnoreCase("y"))
        {

            // get the input from the user
            System.out.println("Please complete the following fields");
            System.out.print("Enter customer type= New or Existing (n/e): ");
            String customerType = sc.next();
            double shirtQuantity = getDoubleWithinRange(sc,
                "Enter Shirt Quantity: ", 0, 1000);
            int colors = getColorWithinRange(sc,
                "Enter number of Colors in Design ($20/color): ", 0, 8);
            
            // get the discount percent
            double discountPercent = getDiscountPercent(customerType, shirtQuantity);

            // calculate the discount amount and total
            double shirtCost = shirtQuantity * 7;
            double discountAmount = shirtCost * discountPercent;
            double subtotal = shirtCost - discountAmount;
            int setupColor = colors * 20;
            double Total = subtotal + setupColor;

            // get the currency and percent formatters
            NumberFormat currency = NumberFormat.getCurrencyInstance();
            NumberFormat percent = NumberFormat.getPercentInstance();
            percent.setMinimumFractionDigits(1);

            // format the result as a single string
            String results =
                  "Shirt Cost:\t"
                      + currency.format(shirtCost) + "\n"
                + "Color Setup Fee:\t"
                      + currency.format(setupColor) + "\n"
                + "Discount Amount:\t"
                      + currency.format(discountAmount) +  "\n"
                + "Current Total (includes applicable discounts):\t\t"
                      + currency.format(Total) + "\n";
