Java 26: Better Language, Better APIs, Better Runtime

Описание: 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).
