6:15-7:30: Josh Long and James Ward: Bootiful Spring AI
The age of artificial intelligence (because the search for regular intelligence hasn't gone well..) is nearly at hand, and it's everywhere! But is it in your application? It should be. AI is about integration, and here the Java and Spring communities come second to nobody. In this talk, we'll demystify the concepts of modern day Artificial Intelligence and look at its integration with the white hot new Spring AI project, a framework that builds on the richness of Spring Boot to extend them to the wide world of AI engineering.

## A Legacy of Innovation and Inspiration
Since its debut in 1996, JavaOne has served as the beating pulse of the Java community. It was the stage where Java technologies were first revealed, APIs were demystified, and friendships among developers were formed over shared purposes and code hacks. JavaOne has featured relevant topics and content that’s helped shape the careers of generations of developers.
The conference’s return in 2026 is more than an event—it’s a recommitment to that original mission: to bring the Java community together to learn, collaborate, and innovate.
## Learn from the Best, Level Up Your Skills
JavaOne 2026 will offer an unmatched learning experience for developers at every stage of their careers. Attendees can dive into expert-led sessions, immersive hands-on labs, real-world case studies covering a wide range of topics—from Java language enhancements and performance tuning to AI integration that accelerates application development and productivity.
Whether you’re exploring the power of a rich pipeline of features originating from OpenJDK or performance-accelerating capabilities, the conference will help sharpen your technical edge and prepare you for the next evolution in building enterprise-grade solutions.
## From Java 10 to Java 25: A Journey of Breakthroughs
The past eight years have been nothing short of transformative for the Java platform. Starting with the six-month release cadence shift in Java 10, the language and platform have delivered a rapid stream of enhancements. Learn about a range of technical improvements spanning from switch expressions, records, pattern matching, structured concurrency, virtual threads, and more.
These innovations reflect the platform’s core principles: readability, maintainability, performance, and backward compatibility — all while embracing modern development needs.
## Community at the Core
The true strength of Java isn’t just in the code—it’s in the people. JavaOne 2026 will honor the developers, contributors, educators, and advocates who’ve helped Java grow into one of the world’s most widely used programming languages. Community-driven sessions, access to Java Champions and Java User Group leaders, and the infamous hallway track will offer meaningful conversations that make JavaOne THE conference for a unique opportunity to share experiences, mentor others, and build lifelong connections.
Your voice shapes Java’s future. By participating in JavaOne—whether as an attendee, speaker, volunteer, or contributor—you help ensure that Java continues to reflect the real needs of developers worldwide.
## The Future of Java: Smarter, Simpler, Stronger
As we look ahead, one thing is clear: Java continues to evolve with purpose. The language and platform are becoming leaner and more expressive, with features that simplify, enhance, and accelerate developer productivity, and open the door to new use cases across cloud, AI, and beyond.
Join us in March 2026 to celebrate everything that makes Java powerful: the innovation, the technology, and most importantly, the people. Visit Dev.java and follow @Java on X/Twitter for more details.
