Mastering Java Multithreading with a Ticket Booking System

How I used threads, synchronization, and shared resources in Java to simulate real-world ticket booking.

Back to Blogs

Concurrency is tricky. Race conditions are real. I built this simulation to really understand `synchronized` blocks and thread safety.

The Simulation

Multiple 'Customer' threads try to book tickets from a single 'TicketCounter' object simultaneously. Without synchronization, two customers could book the last seat.

Key Concepts

I implemented `Runnable` interfaces for the agents. I used the `synchronized` keyword to ensure that the booking method is atomic—only one thread can execute it at a time.
