• Create models
  • Order
• Create DAO
  • OrderDao. To get the order for a specific user create method getByUser().
• Create service
  • OrderService

    public interface OrderService {
        Order completeOrder(ShoppingCart shoppingCart);
        
        List<Order> getOrdersHistory(User user);
    }

• In the mate/academy/Main.main() method create instance of OrderService using injector and test all methods from it.

Attention!!!: you can have some problem with naming of the table. Let's use orders instead of order.
