☕ Cafe Management System

A console-based Cafe Management System built in Java as part of my Programming Fundamentals coursework.

The application allows customers to browse the menu, place orders, and generate receipts, while administrators can manage menu items. It uses Java file handling to store menu data and customer order history, ensuring data persists between program executions.

💡 Programming Concepts Practiced

This project was developed to strengthen core Programming Fundamentals concepts, including:

• Arrays & Parallel Arrays
• Methods
• Loops (for and do-while)
• Conditional Statements
• Switch Case
• File Handling
• Exception Handling

📂 Data Persistence

The application stores data using two text files.

menu.txt

Stores menu items and their prices.

Example:

Burger,15.99
Pizza,30.59
Shawarma,10.09

orders.txt

Stores customer receipts and order history so previous orders are preserved.

2. Display the main menu.
3. Allow customers to browse and place orders.
4. Generate and save customer receipts.
5. Allow administrators to manage menu items.
6. Automatically save menu updates and order history.
