This project demonstrates the use of Virtual Threads and compares changes between Java 21 and Java 25.
It also includes additional features related to Project Loom, listed below:
- Virtual Threads – Introduction to Java’s lightweight threads enabling massive concurrency.
- Continuation – Explanation and demo of continuations for pausing and resuming code execution.
- Virtual Threads Examples – Practical code samples demonstrating how to use virtual threads.
- Scoped Value – Usage of scoped values to share contextual data safely in concurrent code.
- Structured Concurrency – Managing groups of virtual threads as a single unit for better control and error handling.
- Virtual Threads + Spring Boot – Integrating virtual threads into Spring Boot applications for scalable web services.
- Virtual Threads vs CompletableFuture – Comparison of
Virtual ThreadsandCompletableFuturein asynchronous programming.
Before launching the API or running individual classes, you must add the required VM options.
Descriptions of these options can be found inside the respective classes.
