This assignment is enhancing your Project 2 solutions. As for now, you can keep the inventory in a file and upload it to the array available for your program. It is time to think about how to improve the data model and functionality of the application. Note that the three types of products have much in common and something different. Hence, three child classes of an abstract class is a suitable model that allows different pricing methods defined inside different classes. After that, any application can use product classes without knowing how methods work. And if a method needs to be changed, it will be changed only once inside the class definition. Task #1 Add a new property to the product class - a static variable that holds the number of products in the inventory. Its value must grow as reading from the file progresses. Use this variable whenever you need the size of the inventory. Override a default toString() method such that it returns product ID, name, regular price, and type. Update your menu output method such that it uses the toString() method implicitly or explicitly. If you have not done it in your Project 2, make your program repeat until the user decides to quit. The attached file While Loop.java may help to implement the program repetition. Alternatively, you may add the "Quit" item to the bottom of the menu to stop the program.

(y/n)"); } Scanner scan = new Scanner (System.in); System.out.println("Do you want to continue to while (!s.equals("n") ) { System.out.println("Do you want to continue to loop?
