Simple Restaurant Menu Management Application

Project Description

This is a Java-based application designed to assist with restaurant menu management. With simple CRUD features, the application allows users to:

Add Menu Items:
- Regular Menu (code, name, price).
- Special Menu (with additional discount).
View All Menu Items:
- Display a list of regular and special menus in an organized format, including discount details for special menus.
Delete Menu Items:
- Remove menu items using their unique code.

This project leverages Object-Oriented Programming (OOP) concepts such as abstraction, polymorphism, and interfaces.

Abstraction & Polymorphism
- Utilizes the abstract class MenuItem to model generic menu items.
- Implements polymorphism to handle specific details for regular and special menus.
Interface Discountable
- Applies the discount feature for special menu items.
Input Validation
- Ensures entered data (menu code, name, price, discount) adheres to defined rules.
Dynamic Data Structure
- Uses ArrayList to store menu data, allowing flexible additions and deletions.
Text-Based Interaction
- Uses Scanner to process user input for CRUD operations (Create, Read, Update, Delete).
