Life Beyond Java 8, by Trisha Gee Jet Brains Technology Day for Java (2020)

Wasnt Java 8 a fantastic update to the language Lambdas and streams were a huge change, and they have helped to improve Java developers productivity and introduce some functional ideas to the language. Then came Java 9 and although the module system is really interesting for certain types of applications, the lack of exciting language features and uncertainty around how painful it might be to migrate to Java 9 left many applications taking a waitandsee approach, happy with Java 8. But now Java has a new version every six months, and now Java 14 is here. Were all still on Java 8, wondering whether we should move to a later version, which one to choose, and how painful it might be to upgrade. In this session well look at: Which version to upgrade to, Why to upgrade from Java 8, including language features from Java 9 through to 14, What sorts of issues we might run into if we do choose to upgrade.
