🍔 Fast Food Kiosk – Java Swing & Multithreading

A self-ordering kiosk application built in Java Swing, simulating a restaurant workflow with Waiter and Chef threads.
Customers place food orders through a graphical interface while background threads handle preparation and serving, demonstrating multithreading and thread synchronization in Java.

🚀 Features

• 🖥️ Interactive GUI (Java Swing):

  • Home screen with welcome message.
  • Menu screen with food item images and colorful buttons.
  • Real-time order status updates.

• 👨‍🍳 Multithreading Simulation:

  • Waiter thread takes orders and passes them to the Chef thread.
  • Chef prepares items with simulated delays (Thread.sleep).
  • Waiter serves items once notified by the Chef.

• 🔄 Thread Synchronization:

  • Uses synchronized, wait(), and notify() to coordinate waiter–chef communication.
  • Prevents race conditions and ensures correct order flow.

• 🍽️ Order & Table Management:

  • Orders are tied to table numbers.
  • Table number automatically increments after a meal is fully served.
