JCON Europe 2023 | JAVAPRO | 19 June 2023 | Cinedom, Im Mediapark 1, 50670 Köln, Germany

The 7th JCON edition is presented as an in-person conference – again in a multiplex cinema so that you can watch code on the BIG screen!

Java is our profession and JCON is our passion and a lot of fun. We love to provide Java developers with a spectacular 100 % live conference open to the entire Java-User-Group communities.

Focus on Core Java & Cloud-Native Java:
• JCON traditionally focuses on Core Java, Serverside Java, APIs and Frameworks because that’s what we as Java developers work with every day. However, the main topic will be Java-Cloud-Native and Microservices, because this is the future of Java and a must-have for Java developers.
