Experience the world of Java development live from October 5th to 8th

Over 150 sessions, more than 110 speakers and five parallel streams make JCON a digital live event in a class of its own.

From October 5th to 8th 2021, the major international Java community conference JCON Online 2021 will take place. The conference is organized by Java professionals for the entire Java developer community. In more than 150 sessions spread over four days, participants of JCON-Online 2021 will have the chance to refresh their knowledge about development with the Java programming language, learn new things and exchange ideas with each other. More than 110 speakers - including many internationally recognized experts from the Java world - will share their knowledge, experience and expertise with the participants. JCON-Online 2021 continues the digital success format from the previous year. Here, more than 2,000 participants from 51 countries had taken part.

A comprehensive range of sessions covers the full breadth of topic diversity. It ranges from the internals of the Java language to the topics of web development and low code. Topics such as DevOps, Agile and Culture will also not be neglected, providing important insights into teamwork, for example, in order to successfully carry out the next Java project.

JCON 2021 is a special live event. All sessions will be streamed in real time, allowing participation and interaction as if you were present on site. For review and in-depth study, the conference presentations are recorded and form a comprehensive knowledge base for the Developer World of Java even beyond the conference days.
