Answer to Question #200222 in Java | JSP | JSF for sana

Question

Suppose that you are hired by a High-End “Gola Ganda” shop, this shop offers Gola Gandas of all shapes and sizes. They have basic gola gandas of three sizes: Small, Medium and Large. All have different prices  

A customer can add as many toppings on it as they want, the toppings could be more “Sauce”, Condensed Milk, Nutella, etc (more can be added). Every topping has a different cost, and the cost of each topping will be added on top of the cost of the size of gola ganda.  

For example, if a small gola ganda cost, 50 rupees, and a topping of condensed milk cost 10 rupees, and a topping of Nutella cost 20 rupees, and if a customer has ordered a small gola ganda with condensed milk and Nutella then the total cost will be 80 rupees (50 for small gola ganda, 10 for condensed milk, and 20 for Nutella).
