imagine we are designing a system that will allow an owner of a bookstore "The Book Worm", to add books to their inventory so they can keep tracks of what books they currently have in the store.

For the books, we will want to store the title, author, and year published. You should define a class to hold these properties and create a constructor so that an object can only be created if it has all of these properties.

There is also an optional field that we can add to the book which is the sell price if it is known at the time. You should create an additional constructor to allow creating the book with the sell price. You should also use the appropriate constructor based on the input from the user.

All properties of the book should be private but you should have a get method $($getter$)$ for each property.

Once a book is created, it should be added to an "Inventory" object. An inventory object should contain the book that was created, the quantity, and an inventory number that you create. You should create a constructor that takes in all of these properties. The inventory number should start at $0$ and increment after each inventory object is created. The properties of the inventory object should be private but we should have a get method for each property.

Lastly, there should be a Database class that allows you to add an inventory object. For the Database class, you will want to override the default constructor so that you can initialize an ArrayList to hold all of the inventory objects. Your Database class should have the methods that allow an inventory object to be added and allow it to be removed based on the inventory number. Additionally, you should add a method to the class that prints what inventory items exist. You should overload the print method to optionally pass in a "search term" which would print titles that contain that search term.

In the Main class, you will want to prompt the user for four options. One option is to add a book which will then allow them to create a book object and then an inventory object. Another will be to print inventory items which will ask them if they want to print all inventory items or print those that contain part of a title. Finally, they can remove an inventory item by providing an inventory number. The Main class should run until the user types in done which is the fourth option.

It is highly encouraged that you work with a partner on this assignment. Before you start writing the code for this assignment, you should focus on what properties and methods are required and design the classes, properties, and methods you need. Pay close attention to the formatting provided below when you submit your assignment. If you do not match the formatting example below, you will lose points on this assignment.

Tip: If you need to print out a float with two decimal places, below is an example:

float price $=4\mathrm{.}22$f;

System.out.printf$("$Price: $\%\mathrm{.}2$f$",$ price$)$;
