[CIJUG] Getting the Most from Modern Java brought to you by

April 20, 2021 @ 6:00 pm - 8:00 pm CDT

Time to get back in the swing of things, and we kick off our 2021 meetings with a big presentation on modern Java, brought to us by

—- is the new Java community platform with everything you need to do your daily Java development work — with reference materials on the latest OpenJDK versions, vendors, and distributions, together with insights into the latest quarterly updates, articles, blogs, tips and tricks, and much more. And all for free, accompanied by a Slack channel for discussion on all things Java and OpenJDK.

To celebrate and introduce, members of the Foojay community are doing a JUG tour and one of the stops is right here. Come join in, learn about Foojay, and hear Simon Ritter speak about Getting the Most from Modern Java.

With the release of JDK 16, we have had eight (yes eight!) versions of Java in three and a half 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:

· Local variable type inference (JDK 10)
· Switch expressions (JDK 12)
· Text blocks (JDK 13)
· Records (JDK 14)
· Pattern matching for instance of (JDK 14)
· Sealed classes and changes to Records (JDK 15)

For each recent JDK, we’ll also highlight the most useful additions to the core class libraries. At the end of this session, you’ll be all set to write modern Java code!
