Kotlin in action

In a live coding session/workshop, Jarno Walgemoed and Stephan Oudmaijer will highlight some of the features Kotlin has to offer to developers coming from the Java ecosystem. Making this more tangible, we will start with a Java/Spring Boot based webapplication and migrate this to Kotlin while maintaining the interoperability with existing Java code and adding new features as we go. The goal is to provide a practical insight in how Kotlin’s concise and expressive syntax could help developers write code that’s easier to understand and maintain.
