Exploring reactive programming in Java
summary
Live coding walks through eight concrete levels from raw threads to an HTTP/2 client demonstrating what actually changes: examples use JShell, show executor services and fork/join, then completable futures with 52 methods plus Java 9 additions like completeOnTimeout and copy, then the Flow API with SubmissionPublisher to illustrate backpressure, and a tiny HTTP server and client over HTTP/2 that run end to end. The demos compile and execute, proving the tools and gaps at each level.
