data structure (java) language here is the test so i need the code of each class

Implement the following class diagram that models Order Management System. Customer Order Item -Dint -name String -No int Client Customer tems. Arraylist of em shipped boolean code int -price double Book Device HSBN String -title: String -Name String -Type: String 1- To class Order, add method total that returns total of all order's items prices. 2- Create a new class called Company that has array list of: customers, books, devices, orders, and add setter/getter for each one of them. Add the following methods : a) unShippedOrders(): it returns array list of all orders that are not shipped (shipped field is false) b) totalBookSales(): it returns total of book sales (money) in all orders. c) customerOrder(int): it receives a customer id, and returns array list of all his orders. d) moreBooks(): it returns an array of customers who bought books and devices but spent more money on books than on devices. e) highest(): it returns name of the customer who has the maximum sale! The output : Unshiped orders: ||| Total of book sale: 700.0 The orders of customer no Customers who spent money to buy books more than devices Nasaer ------ The best customer : Khaled import java.lang.reflect.
