JavaOne 2022 is a wrap!

Here are resources from the conference.

Last month’s JavaOne conference—our first in-person get-together since the start of the pandemic—celebrated all things Java. Great people, interesting projects. Or is that great projects and interesting people? Either way, the best part of that experience was seeing so many friends and colleagues. (Well, the other best part was taking part in Thursday’s community keynote, “The Future of Java is You,” where I got to talk about Java Magazine.)

I’d like to call your attention to the following resources about JavaOne:

• The technical keynote video
• GraalVM in OpenJDK and More JavaOne Announcements video
• Introducing the Java SE Subscription Enterprise Performance Pack
• Tom Smith’s story on DZone, JavaOne 2022: Java Continues to Evolve
• Paul Krill’s article on Infoworld, Oracle makes Java discovery service free to all
• Also from Paul, Oracle unveils performance pack for Java 8

Nearly half of the learning opportunities at JavaOne are led by experts outside of Oracle

July 29, 2022

You’ll meet a lot of experts at JavaOne 2022—and not just experts from Oracle’s Java Platform Group.

As my colleague Chad Arimura, vice president of Java developer relations, explains in a recent blog post,

Of the hundreds of sessions that you will find at JavaOne, almost half of them are being led by members of the community. The content catalog might not be updated with all of the sessions and speaker information yet, but it will be soon, and you can look for yourself. And this doesn’t take into account the Unconference and famous ‘hallway track’ where speakers and audiences congregate.

Chad adds that JavaOne will have a range of community-led panels and birds-of-a-feather sessions on topics such as “Nurturing a Community” (led by Vincent Mayers), “Jakarta EE” (led by Ivar Grimstad), and “Mentoring Java Developers” (led by Dervis Mansuroglu).

One session you won’t want to miss (I certainly don’t want to miss) is “Functional Programming Idioms in Java,” taught Venkat Subramaniam. Here are two recent articles that he wrote about functional programming for Java Magazine.

• Functional programming in Java: Lists, lambdas, and method references
• Functional programming in Java: Lambda reuse and lexical scoping

Oh—and the Unconference? It’s where you get to make up the curriculum! Here’s how it works: Everyone at JavaOne can vote on a selection of Java topics. Then, you’ll participate in a collaborative discussion on the winning topic with some of the top Java experts from all around the world. I’ll share more details when things are locked down.

JavaOne 2022 is in Las Vegas from October 17 to October 20. Note that early pricing has been extended until August 14; that’s a savings of US$200. Here’s the registration link.

Mikael Vidstedt explains why you should bring your team to Oracle CloudWorld and JavaOne 2022

July 13, 2022

There are hundreds of great learning sessions planned for Oracle CloudWorld and JavaOne 2022, and that’s only part of the story.

From aviation to aerospace, finance to banking, retail to social, and across many more industries, Java helps power the world around us. Continual Java innovation by Oracle allows you to address the application challenges of today and the opportunities of the future. Keynotes, labs, and sessions at JavaOne will showcase Java’s value in addressing modern application development challenges and strengthen your Java skills.

Hear why Mikael Vidstedt—director of software engineering, Java Virtual Machine, at Oracle—can’t wait for JavaOne.

JavaOne 2022 is part of a group of four interlocked conferences; if you sign up for one, you can enjoy all of them.

JavaOne is coming to Las Vegas in October 2022

After taking a pandemic-related holiday, the in-person developer conference returns.

May 18, 2022

Mark your calendars: The long-running JavaOne technical conference is officially returning! JavaOne will be held in conjunction with Oracle CloudWorld in Las Vegas, Nevada, from October 17 to October 22, 2022.

Like many events of all kinds, Oracle’s tech conferences were cancelled during the pandemic. The last Oracle developer conference was in 2019 in San Francisco; the plan was to move it to Las Vegas in 2020, but, well, no.

In 2018 and 2019, the developer conference carried the name Code One. For 2022, the name JavaOne is back!

I attended nearly all the JavaOne (and Code One) conferences since the Sun Microsystems era, and I think I was at the first one, in 1996. The Java Ring given away in 1998 is still a prized possession, and don’t get me started about my Duke plush toy collection.

The JavaOne 2022 plan is to include a mixture of keynotes, technical sessions, hands-on labs, tutorials, and birds-of-a-feature (BOF) informal gatherings. I’m sure you’ll learn a lot about Java 18, Java 19 (to be released in September), and the future of the platform.

Please bookmark this page. We’ll update that page as the JavaOne program fills out. We’ll also let you know when registration opens.
