Java-Related Conferences

I think that every Java developer should have the opportunity to attend a technical conference every year or so. Here are the major annual conferences, in order by date. Dates shown in green are still to come; dates in red are in the past, and either the organizers are slow at publishing next year's dates, or they failed to notify me, or I simply didn't get the memo. Organizing a conference is a tremendous drain on the psyche, so please do not blame the organizers for not listing next year's dates while they're still recovering the last one! Most of these conferences come around every year, so check up on their web site if there's one whose location interests you.

This list includes pure Java conferences, as well as Android (since most Android apps are built using Java, for now at least), some that focus on other JVM languages and/or technologies, and some large open-source conferences that include significant Java content.

To add another conference: send me the details using this template in CSV or SQL. Updates/Corrections: send email to conferences at this domain. "If you keep me in the loop I'll keep you in the list." As always, the editor's decision is final! :-)

Some conferences are listed in the events column of Oracle's free Java Magazine. In addition, some companies have many other conferences that may be valuable, such as O'Reilly Media's Conference Schedule.

Recent major changes: AnDevCon discontinued. JavaOne renamed to Oracle Code One to include other languages.
