JAVA program: Create a book Order Class.Every book order object includes a name of the book, number of books in the order, and individual price of the book. You should have methods that compute the tax paid on the order(7.5%of the total cost), compute the shipping cost of the order($2 per book),compute total cost of the order including tax and shipping cost, and print out all necessary information about the order as a whole. You should also have a tester program that allows the user to make three different orders prompting them to input all necessary order information. The tester program should let the user know the final cost of their individual orders as well as the total cost of all three combined. Print all necessary information in the proper format.(Please give separate order class and tester class)
