🍽️ Restaurant Functioning Using Multi-threading and Synchronization

This Java project simulates the functioning of a restaurant using multi-threading and synchronization primitives. The model handles essential restaurant operations such as:

Checking table availability

Assigning tables to customers in order of arrival

Managing cook availability

Tracking availability of menu items (burgers, fries, coke)

Coordinating concurrent tasks to satisfy customers efficiently

🚀 How It Works

Multi-threading: Different threads simulate cooks, diners, and machines working in parallel.

Synchronization: Ensures that tasks like table assignment and food preparation happen in the correct order without conflicts.

Order Management: Orders are queued and processed in the order of arrival.

Resource Availability: Tables, cooks, and machines are shared resources synchronized to prevent race conditions.

⚙️ How to Run Locally

Compile all .java files:

javac Restaurantfolder/*.java

Run the main program:

java Restaurantfolder.App

The program reads input files (input1.txt, input2.txt) for orders. Make sure these files are in the same directory.

🛠 Concepts Demonstrated

Java Threads (extends Thread or implements Runnable)

Synchronization (synchronized, wait(), notify())

Shared resource management (tables, machines)

Producer-consumer model for order processing

Handling concurrent customer requests fairly
