| A Great 2025 with Java |
| A Year End Message to the Java Community |
|
Thank you to the global Java developer community for making 2025 such a remarkably successful year.
Your passion for learning, sharing, and cooperating together continued to strengthen the ecosystem and helped inspire developers at every stage of their journey to advance their Java skills and peer connections. |

Through continual community participation, you helped ensure that Java remained vibrant and relevant this year. There’s no better way to showcase this success than these important highlights:
The return of the JavaOne Conference (March 2025): The long-awaited comeback of JavaOne brought the community together again for deep technical learning, meaningful conversations, and renewed energy around the future of Java.
The Successful Launch of Java 25 (September 2025): With participation through the OpenJDK community, the Java 25 release showcased its continued evolution of delivering powerful new capabilities and reaffirming its commitment to performance, reliability, and developer productivity.
Growth of Java User Groups: The addition of 14 new Java User Groups expanded opportunities for local collaboration, enabling developers around the world to share ideas, learn together, and build stronger regional connections around the value of Java.
New Java Champions: Welcoming 12 new members into the Java Champions program broadened the reach of community expertise and amplified Java knowledge sharing across conferences, blogs, and user groups.
Duke’s Corner Podcast Success: The recording of 18 Duke’s Corner Podcast episodes gave developers unique insights, experiences, and perspectives directly from respected luminaries within the Java community to build even greater inspiration around using Java.
With your continued curiosity, generosity, and participation, the momentum from 2025 sets the stage for an even more exciting and impactful 2026 for the Java community. I look forward to partnering with you again over the next 12 months to make Java shine even brighter. My sincerest thanks for all you do to keep Java vibrant.

If you’ve never been to JavaOne, check out JavaOne 2025 (videos, photos) and JavaOne 2022 (videos, photos).
Next year will be better than ever. JavaOne is the only Java conference in the world that draws the highest percentage of engineers from the Java Platform Group — the team that builds Java at Oracle. You just can’t beat that concentration of core technical talent in one space. But we have fun too, so you’ll not want to miss this event! Everyone will be there!
If you are attending, speaking, sponsoring, or exhibiting, please subscribe here to get the latest JavaOne 2026 news. And we’ll see you in sunny California in March! |

Chris Hermansen: Don't be Afraid to Create
Chris Hermansen is a data analyst, developer, and consultant from Canada and he talks about the technical features in Java, developer creativity, career advice for students, and the use of Java in real world applications such as forestry. Here Chris comments on the JVM, the community, NetBeans, and the Java language: “It's a pretty cool thing. It's a movement. It's not just a programming language."
Barry Burd: Teaching Java as an Art Form
Barry Burd is a computer science teacher, an author from New Jersey, and a co-leader for two Java User Groups. Here Barry comments on the beauty of computer science: “When I think, why computer science? It’s because it’s artistic! It’s, oh yeah, I mean, it’s useful. And I certainly respect that. And I’m glad that people develop useful things for it. But my own interest in it is the beauty of it.” |
