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

Sample Output

Future Improvements

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