Track Overview

Modern Java

Java is a trusted friend which continues to grow, flex, and surprise us. But with new capabilities come new questions. Is Java cloud native? How do I make reactive work for me? How do I know if what we’re making actually, you know, works? Am I missing a trick? What capabilities am I not taking advantage of?

In this track we will explore the ways modern Java can make our life better … once we know where to look. We’ll see what’s new and what’s on the horizon in the Java language. We’ll also hear from practitioners about what’s giving them headaches and, most importantly, how they fixed it.
