What is `Project Loom`’s virtual thread and how does it differ from a platform thread?

Explanation

Virtual threads in Project Loom are JVM-managed lightweight threads that can run millions concurrently without blocking OS threads, while platform threads directly map to OS threads. This distinction allows for more efficient thread management in Java applications.

Key points

Virtual threads are JVM-managed and lightweight
Platform threads map 1:1 to OS threads
Virtual threads enable high concurrency without blocking OS threads
Platform threads are heavier and directly tied to OS threads
