Java Champions are developers from around the world who are recognized for the contributions to the Java community. Champions are about sharing their knowledge with developers. This coming January, after successful conferences for the past three years, will be our fourth conference organized by Champions and featuring Champions in the presentations. Our audience is the 14 million Java developers world wide.

The jChampions Conference will run for four days in January 2025 on Thurs 1/23, Fri 1/24, Mon 1/27, & Tues 1/28. Rather than trying to run like a traditional in person event, each day will feature 7 sessions. Sessions will begin at 9:00 EST and end at 17:00 EST. After each session there will be time for participants to speak with the presenters.
