The New HTTP Client API in Java 11
summary
Java 11 ships a standardized java.net.http client that replaces HttpURLConnection, supports HTTP/2 and HTTP/1.1, and exposes synchronous and CompletableFuture-based async APIs. It uses Flow reactive interfaces so request/response bodies are handled by pluggable BodyPublisher/BodySubscriber implementations, letting one compute an MD5 on streaming bytes without buffering the whole file. Immutable clients and builders configure executor, timeouts, TLS and HTTP/2 settings, and the API includes server push (PushPromise) handlers and sensible default body handlers.
