Answer to Question #262351 in Java | JSP | JSF for ANNIE

Question

Provide a method calculatePrice() that calculates and returns the price of this sandwich according to the rates given in the above table. E.g. the price of a sandwich with 3 bread slices, 2 cheese slices, 2 tomato slices, 3 patties, mustard, no ketchup, no ice berg with grilling will be calculated as 3 * 20 + 2 * 30 + 2 * 5 + 3 * 70 + 5+ 0 + 0 + 10 7. Provide a method applyDiscount(double disc) that calculates the price, applies the discount % given in the argument and returns the discounted price of the sandwich.E.g. if the method is called on a sandwich whose real price returned by the calculatePrice function is 550 and applyDiscount(10) is called, then a ten percent discount will be calculated as 550 * 10/100 = 55. Now this function will return the discounted price as 550 – 55 = 495. (Please note that this is just an example, do not hard code these values in your function).
