Java 21: Virtual Threads - A different async/await with Code Examples

Java 21 introduces lightweight concurrency with Virtual Threads.
Virtual threads are a different approach to asynchronous programming. Instead of having to rewrite everything using async/await keywords. Java will take care of everything.
Discover the changes introduced with JDK 21 and learn how Virtual Threads behaves with code examples demonstrating I/O Bound Tasks, CPU Bound Tasks, and Cooperative CPU Bound Tasks. Learn how the synchronized keyword and locks work in the context of Virtual Threads.
