Java

Six years ago we accelerated the pace of new releases in order to keep Java vibrant in an ever-changing world of competing platforms and new styles of application deployment. That worked out better than most anyone hoped or expected, enabling a rate of innovation and delivery not seen since the early days of the platform. We’ll take a look back at features delivered recently, and

Let's talk about Loom and 23. So for JDK 23, what we want to be able to do, is update the structured concurrency API. We need a lot more feedback from real-world usage on that but we have a lot of ideas and a lot of shapes of APIs on the table to improve that API. We also need to move forward the scoped value API, so that's in preview in 21 and 22, but I think it's actually close t

JEP 468 proposes a solution to the verbosity that can come from modeling mutable state with immutable records: *derived record creation* aka *with expressions* aka *withers* . That'll make it easy and succinct to create a copy of a record instance while changing just a few components. *Links* JEP 468: https://openjdk.org/jeps/468 It's not names parameters: https://mail.openjdk.org/

Today I'm talking about how we in the Java Platform Group are trying to make Java developers more productive. And in particular we're interested in making _beginner_ programers more productive. How do we make it easier for beginner programers to write their first program and slowly learn the bits of the Java language as they need it? Check out the JEP concerning on-ramp experience.

*JDK Flight Recorder (JFR)* is a low overhead profiling and troubleshooting framework built into the Java Virtual Machine. It comes with a powerful programming API that allows you to create application specific events. The API can also be used as a datasource for your own infrastructure for example when building dashboards and triggers. This talk will deep dive into the API and loo
