Getting the Most from Modern Java

With the release of JDK 17, we have had nine (yes nine!) versions of Java in four years.

Java developers are now being provided with more new features at a faster pace than at any time in its over quarter-century history.

Many of these new features provide exciting new language level changes, as well as useful new APIs.

In this session, we’ll explore in detail what these changes are and how best to use them (as well as advice on when not to use them). We’ll also explain the significance of preview features and incubator modules.

We’ll cover the following new language features:

· Switch expressions (JDK 12)
· Text blocks (JDK 13)
· Records (JDK 14)
· Pattern matching for instanceof (JDK 14)
· Sealed classes and changes to Records (JDK 15)
· Pattern matching for switch (JDK 17)

For each recent JDK, we’ll also highlight the most useful additions to the core class libraries such as the Vector, Foreign-Memory Access and Foreign Function APIs.

At the end of this session, you’ll be all set to write modern Java code!

JReleaser: Releasing at the speed of light

Your project has reached that stage when it’s a good idea to post binaries, but new questions appear such as where should they be posted? How do make it easier for users to install and discover your binaries? Where should releases be announced? Most importantly, can answers to these question be automated? Enter JReleaser, a tool that provides answers to these questions and more. JReleaser may be used to create GiHub/GitLab/Gitea releases and publish binaries that can be consumed from different distribution channels such as Homebrew, Snap, Scoop, and more. Once published, the release cab be automatically announced on Twitter, Slack, Gitter, Discord, and other communication channels. Come to this session to learn how JReleaser can help you release, publish, and announce binaries with ease, and fast!
