🚀 Introduction: Why Java Virtual Threads?

Java has always been a powerful language for multithreading and concurrency, but traditional threading models struggle with scalability.

💡 Enter Java Virtual Threads — a revolutionary feature introduced in Java 21 as part of Project Loom that enables massive concurrency without the overhead of traditional threads.

What’s Special About Virtual Threads?

• Ultra-lightweight threads that run millions of tasks concurrently.
• Managed by the JVM instead of the OS, eliminating costly thread context switching.
• Highly scalable for I/O-bound applications (databases, web servers, messaging).
