define instance variables for the class, a constructor to initialize those variables, one or more mutators to modify the variables, one or more accesssors

## Problem Statement ### Defining Classes Write and document the definition for the `Product` class. The `Product` class represents an item that would appear for sale on a website or in a department store (like a toaster). #### Diagram Explanation The diagram depicts the `Product` class, which includes the following: - **Fields:** - `description : String` - `price : double` - `productNumber : int` - **Methods:** - `getCost(int qty) : double` - `Product(int pNum, String pDesc, double price)` - `setDescription(String newDesc) : void` - `setPrice(double newPrice) : void` - `toString() : String` ### Additional Details - 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.
