The class diagram below shows an Order class that "has a" Customer and zero or more Items. Order class should contain private Customer m_cust; private ArrayList<Item> m_items; public Order(Customer cus t) public void additem(Item i) public String toString() Item class should contain private String m_desc private int m_qty private double m_price public Item(String des c, double price, int qty) public String toString() Customer class should contain private String m_first; private String m_last; public Customer(String first, String last) public String toString() Please create the Order, Customer, and Item classes shown above. I have provided you with a read-only Main class that you can use to test your code. When you have completed the Order, Customer, and Item classes, running the Main program should produce the following output: Order for Smith, Tom Order Items: Greeting Card: 1 at 1.5 Baseball Glove: 1 at 54.0 Notebook: 3 at 2.5 public class Main{ public static void…
