Sahoo dhaba delivery system using java

By Abir Basak

The Sahoo dhaba delivery system project is a Java application that allows customers to place dhaba orders. The customer can select their food by the menu card and it will provide the bill.

The above code implements a basic Dhaba Delivery System using Java. It consists of three classes: `FoodItem`, `Order`, and `DeliverySystem`. Let's understand each class and its functionalities:

1. `FoodItem` class:
- This class represents a food item available for ordering in the dhaba.
- It has two attributes: `name` (representing the name of the food item) and `price` (representing the price of the food item).
- The class provides getters to retrieve the name and price of a food item.

2. `Order` class:
- This class represents an order placed by a customer.
- It contains a list of `FoodItem` objects (`items`) representing the selected food items in the order.
- It also has a `total` attribute that stores the total price of the order.
- The class provides methods to add and remove food items from the order, calculate the total price, and retrieve the list of items and the total price of the order.

3. `DeliverySystem` class:
- This class manages the delivery system and all the placed orders.
- It uses a `Map` data structure where the keys are customer names, and the values are `Order` objects.
- The class provides methods to place an order, remove an order, retrieve an order by customer name, and get a list of all orders.

4. `DhabaDeliverySystem` class:
- This class contains the `main` method where the execution starts.
- It creates an instance of the `DeliverySystem` class and initializes a few `FoodItem` objects.
- It creates instances of the `Order` class, adds food items to the orders, and places the orders using the `placeOrder` method of the `DeliverySystem`.
- It demonstrates the functionality of the system by displaying all orders, removing an order, and displaying the orders again.

Overall, this code provides a basic framework for a Dhaba Delivery System, allowing customers to place orders, calculate the total price, and manage the orders efficiently. You can extend and modify this code according to your specific requirements and add more features to enhance the functionality of the system.
