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 red are in the past, and either the organizers are slow at publishing next year's dates, or I've missed the update. But most of these conferences come around every year, so check up on the web sites.

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