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 main(String args[])
    {
        Main m = new Main();
        m.go();
    }
    
    public void go()
    {
        Customer c = new Customer("Tom", "Smith");
        Order o = new Order(c);
        o.addItem(new Item("Greeting Card", 1.50, 1));
        o.addItem(new Item("Baseball Glove", 54.00, 1));
        o.addItem(new Item("Notebook", 2.50, 3));
        
        System.out.println(o);
    }
}
