Reactive Java

Writing reactive Java services is becoming more common. With Java Reactive Streams becoming part of JDK 9 and Spring 5 including WebFlux, this trend is only going to continue. In this talk, Bartosz will explain how reactive services can help us deliver better solutions on the server side. He will also introduce Reactive Streams and Reactor based WebFlux with a practical demo. Microservices changed how we deliver software, reactive microservices can be the next big change.

About the speaker:

Bartosz Jędrzejewski is a Lead Software Developer at Scott Logic. He uses Java and JavaScript to solve all kind of problems- from hobby projects to enterprise financial systems. Currently, he's fascinated by Microservice Architecture and writes about it on his blog - e4developer.

JDK 9, 10, 11 and Beyond: Delivering New Feature in the JDK

JDK 10 was released only six-months after JDK 9, demonstrating that the new fast cadence for the OpenJDK works. Even with such a short development cycle, there were still over a hundred new features covering the language, core libraries and the JVM.

In this session we’ll take a look at how the Java platform is evolving with the introduction of big features like the Java Platform Module System (JPMS) in JDK 9, local variable type inference in JDK 10 and dynamic class file constants in JDK 11. We’ll also cover many of the smaller features that will make your life as a developer easier.

What might JDK 12, 13 and 14 include? To answer that question, we’ll explore some of the longer-term plans for Java, like project Amber, Loom and Valhalla.
