You are tasked with developing an online food ordering system in Java using interfaces. The system

should include interfaces for $`$FoodItem$`$ and $`$Order$`,$ which will be implemented by various

classes representing different types of food items and orders. Additionally, you need to write a driver

program to test the functionality of the implemented classes.

Requirements:

$1.$ FoodItem Interface:

$-$ Define an interface named $`$FoodItem$`$ with the following methods:

$-`$String getName$()`$: Method to get the name of the food item.

$-`$double getPrice$()`$: Method to get the price of the food item.

$-`$String getDescription$()`$: Method to get the description of the food item.

$2.$ Order Interface:

$-$ Define an interface named $`$Order$`$ with the following methods:

$-`$void addItem$($FoodItem item$)`$: Method to add a food item to the order.

$-`$double calculateTotal$()`$: Method to calculate the total cost of the order.

$-`$void displayOrderDetails$()`$: Method to display the details of the order,

including the items ordered and the total cost.

$3.$ Implementations:

$-$ Implement the $`$FoodItem$`$ interface in classes representing different types of food

items such as $`$Pizza$`,`$Burger$`,`$Salad$`,$ etc. Each food item class should

provide implementations for the methods to return the name, price, and description of

the food item.

$-$ Implement the $`$Order$`$ interface in a class named $`$FoodOrder$`.$ This class should

maintain a list of food items added to the order and provide implementations for the

methods to add items, calculate the total cost, and display the order details.

$4.$ Driver Program $($Main Class$)$:

$-$ Write a driver program named $`$OnlineFoodOrderSystem$`$ to test the functionality

of the implemented classes.

$-$ Create instances of different types of food items $($e$.$g$.,$ pizza, burger, salad$).$

$-$ Create an instance of the $`$FoodOrder$`$ class and add the food items to the order.

$-$ Display the details of the order, including the items ordered and the total cost.
