QueueSimulator

A Java-based queue simulator that manages both regular and priority queue orders using core data structures.

Why I Built This

I'm interested in how backend systems behave internally and how simple data structures can simulate real-world workflows. This project is part of my journey exploring Java backend systems, simulations, and developer-focused software projects.

Features

• Priority and regular order handling
• FIFO (First In First Out) queue processing
• Enqueue and dequeue operations
• Queue inspection using peek()
• Queue visualization with displayQueue()
• Unique order ID generation
• Object-oriented design using separate classes

---

Technologies Used

• Java
• Java Collections Framework
• Queue Interface
• LinkedList

How to Run

1. Clone the repository

git clone https://github.com/JavaLabs-io/QueueSimulator.git

2. Open the project in VS Code or any Java IDE
3. Run Main.java from the src/ folder

Sample Output

--- Current Queue ---
Priority orders (4):
  [PRIORITY] Order #1 | Saket | Item: CinnamonRoll
  [PRIORITY] Order #2 | Taylor | Item: Sourdough
Regular orders  (2):
  [REGULAR] Order #4 | Alice | Item: Bread
  [REGULAR] Order #6 | Ajaz | Item: idk
---------------------
=== Processing Orders ===
Serving  (PRIORITY): [PRIORITY] Order #1 | Saket | Item: CinnamonRoll
Serving  (PRIORITY): [PRIORITY] Order #2 | Taylor | Item: Sourdough
Serving   (REGULAR): [REGULAR] Order #4 | Alice | Item: Bread
Serving   (REGULAR): [REGULAR] Order #6 | Ajaz | Item: idk

Future Improvements

• Cancel order functionality
• Search orders by ID
• JUnit tests
• GUI version
• REST API integration
