Java 26: Better Language, Better APIs, Better Runtime

Since JavaOne 2025, JDK 25 was released, the latest version with long-term support. But Java never stands still; it's already time to ship JDK 26. This talk summarizes the most important changes between Java 21 and 25: - from unnamed patterns and flexible constructors to module imports - from the foreign-function and memory API to stream gatherers and the class-file API - from a simpler `main` to launching multisource-file programs - from Markdown in JavaDoc to quantum-resistant encryption - from faster launch times to improved garbage collection ... before taking a closer look at the newest release, including its preview features: - Primitive patterns and lazy constants - Updated structured concurrency - PEM encoding and HTTP/3 support - New command-line options to enable deep reflection There are plenty of features in the language, API, and runtime to discuss; whether new, improved, or finalized. Let's go over them. Presented by Nicolai Parlog (Oracle) at JavaOne 2026 (CA, March 2026). All https://www.youtube.com/playlist?list=PLX8CzqL3ArzUMVSzm-z_-if8BIB55EGl4 talks.
