need it in java language and the output must be as shown down

Implement the following class diagram that models Order Management System. Item Customer -Dint -name String Order -Noint Client: Customer Items: Arraylist of item -shipped boolean -Codeint -price double Book Device ISBN String e 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 list 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 Grading: Implementing all classes according to the class diagram Method total in Q1 Method unShippedOrders ( Q2-a Method totalBookSales0 Q2-b Method customerOrder(int) Q2-c Method moreBooks(): Q2-d Method highesto:Q2-e Total 0.5 0.5 0.5 0.5 This is the test for HW#1, the output should be same as the one below import java.lang.reflect.
