Problem Statement Defining Classes Write and document the definition for the Product class. The Product class represents an item that for sale on a Web site or in a department store (like a toaster). would appear Product Class B Fields description : String price : double productNumber : int B Methods 9 getCost(int aty): double O Product(int pNum, String pDesc, double price) O setDescription(String newDesc): void 9 setPrice(double newPrice) : void * tostring) : String • Each Product object has three instance variables: description, productNumber and price. • The class has one constructor that takes three parameters in the order productNumber, description and price. • The class has one accessor method named getCost(int qty) which returns the price for qty items of the Product. • The class has two mutator methods-setPrice() and setDescription()-that modify the corresponding instance variables. • The class has a toString() method that returns the Product as a String in the form: 34567: Small Toaster, $ 17.95. Note: use concatenation to construct the returned string. Do not use the String.format() method to format the returned value.
