Answer to Question #262319 in Java | JSP | JSF for PPP

Question

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). 8. Provide the toString method that returns a well formatted string showing the detailed composition of the sandwich e.g. Bread Slices : 2 Cheese Slices : 2 Patties: 1 Tomato Slices: 0 Mustard: No (if not added) Ketchup: Yes Iceberg : Yes Grilled: No Price: Rs. 200 (dummy value given here but you will calculate programmatically and provide correct value here)
