Нужна помощь в поиске ошибки в этой программе, компилируется, но не нужна компьютерная цифра

Question

Эта программа компилируется и запускается, но не вычисляет страховую премию. Я работаю над этим несколько дней и не могу понять. Раньше он запускался в другой версии, но мы должны иметь 2 класса сейчас, и теперь он не вычисляет страховку, или он отображается как ноль в каждом ответе. Мы также должны использовать панели для ввода.

    This program will demonstrate the Premium and BMI classes. This program will prompt users for input, 
    use that input to calculate BMI and their insurance rate. 
    Output will be the customer profile: name, age, smoker status, height, weight and insurance premium cost. 
    Program will then ask user if they want to create another profile.

Answer 1

Если вы не получаете ошибок компилятора, это логическая ошибка в вашем коде.

Выглядит как метод calculateInsurance никогда не называется.
