Why am I getting “NoSuchElementException” When I can print everything from textfile?

I’m able to read everything from the text file and print the data yet I get a “No Such Element” Exception. All the solutions i’ve found say to use “HasNext” in while loop and yet it doesn’t seem to work for me

public void fileReader() throws IOException {

    String id;
    String brand;
    int yearOfManufacture;
    int numSeats;
    double rentalPerDay;
    double insurancePerDay;
    double serviceFee;
    double discount;
    String model;
    String type;
    String color;
    ArrayList<Vehicle> vehicleArray = new ArrayList<>();
    File file = new File("C:/Users/jockg/Downloads/Fleet (1).csv");
    Scanner scan = new Scanner(file);
    scan.useDelimiter("n/n");

    while (scan.hasNext() || scan.hasNextDouble() || scan.hasNextInt()) {

        id = scan.next();
         System.out.println(id);
        brand = scan.next();
         System.out.println(brand);
        model = scan.next();
         System.out.println(model);
        type = scan.next();
         System.out.println(type);
        yearOfManufacture = Integer.parseInt(scan.next());
         System.out.println(yearOfManufacture);
        numSeats = Integer.parseInt(scan.next());
         System.out.println(numSeats);
        color = scan.next();
         System.out.println(color);
        rentalPerDay = Double.parseDouble(scan.next());
         System.out.println(rentalPerDay);
        insurancePerDay = Double.parseDouble(scan.next());
         System.out.println(insurancePerDay);
        serviceFee = Double.parseDouble(scan.next());
         System.out.println(serviceFee);
        if (scan.next().equals("N/A")) {
            discount = 0;
        } else {
            discount = Double.parseDouble(scan.next());
        }

         System.out.println(discount);

        Car newCar = new Car(id, brand, yearOfManufacture, numSeats, rentalPerDay, insurancePerDay, serviceFee,
                discount, model, type, color);
        vehicleArray.add(newCar);
    }
}

This is the Exception I get:

Answer

• your CSV has actually two delimiters: comma and new line. Try: scan.useDelimiter(",|\R");
• discount is read twice for numeric values, try:

    String discountStr = scan.next();
    discount = discountStr.equals("N/A") ? 0 : Double.parseDouble(discountStr);
