Learn about the future of the Java Platform
Join Brian Goetz (Java Language Architect) on a whirlwind tour of recent enhancements and future directions for the Java language with a special emphasis on Project Amber and Project Valhalla.
Java is a 30-year success story, made possible because its development consistently aligned with users' needs. In its early days, the platform required new features quickly, but over time, minimizing code breakage while carefully evolving the platform became essential. Critical junctures along that path included the introduction of modules and the current strive toward integrity by default.
Many Java features, existing and future, can meet the demands of AI. Existing features include the Foreign Function and Memory API and the Vector API. Future features include those proposed by Project Valhalla and Project Babylon. This video discusses these features and how they might be used by Java libraries and applications to build competitive AI solutions.
To assist performance, portability, and security, the Java Platform is progressing toward a state where its abstractions, as well as programmer-defined abstractions, can be made robust and invariants can be locally guaranteed. Libraries may violate some invariants but only if selectively allowed by the application. This session covers the why and how of the vision of "Integrity by Default".
