Java Champion Simon Ritter - Art of Java Pattern Matching and Java on CRaC Talks

Hosted by Belfast Java User Group (JUG)


We're excited to bring you another fantastic speaker. Join us on June 30th for two talks by Java Champion Simon Ritter.

19:00 The Art of Java Language Pattern Matching

Pattern matching is where application logic combines testing if an expression has a specific type or structure and then extracting components of its state for processing.
In this session, we’ll look at the details of these two new language features, as well as a more general look at pattern matching. We’ll also explore future features in this area, such as record patterns (scheduled for JDK 19) and array patterns, which may be included in a subsequent Java release.

By the end of the session, you’ll be all ready to make use of these powerful new features!

20:30 Java on CRaC

A new project has been proposed and accepted into OpenJDK called CRaC (Coordinated Restore at Checkpoint). The goal is to research the co-ordination of Java programs with mechanisms to checkpoint (snapshot) a running application. Restoring from the snapshot could solve some of the problems with the startup and warmup times, especially in microservices.
In this session, we’ll look at the main challenges for such a project, potential solutions and the results from a proof-of-concept implementation.
