You are tasked with writing a program that will keep track of items sold by a retail store.

We are now going to add additional types of products through the use of inheritance. In addition to the standard Product, there will be a Book and Food class, each with their own unique properties.

We will also need to keep track of the of the inventory or number of specific products available for sale for each item.

Requirements:

If a retail price is not supplied, the retail price should be set to a $20\%$ markup from the wholesale price.

The Food and Book items should inherit all the properties of the Product item

Foods cannot be added to the inventory without an expiration date.

Book will have an author property that should default to "Unknown"

Implement a toString method for Product, Food, and Book.

If the description for an item is not set, do not include it in the toString.

Add a property and methods to track the number of items in inventory for each item.

Negative inventory amounts are not allowed.

Add code to print any items that have an inventory amount less than $5.$

Starter code:

Product headphones $=$ new Product$("$Wireless Headphones", $178)$;

headphones.setStock$(1)$;

System.out.println$("-----------------------$

$//$

$//$ Add the code here to print Low Stock Levels

$//($items with less then $5$ in inventory$).$

Sample output:
