:description: This post looks at using Gatherers (JEP 461) with Groovy.
-An interesting feature being previewed in JDK22 is _Gatherers_
-(https://openjdk.org/jeps/461[JEP 461]).
+An interesting feature in recent JDK verions is _Gatherers_:

+* https://openjdk.org/jeps/461[JEP 461: Stream Gatherers (Preview in JDK 22)]
+* https://openjdk.org/jeps/473[JEP 473: Stream Gatherers (Second Preview in
JDK 23)]
+* https://openjdk.org/jeps/485[JEP 485: Stream Gatherers (JDK 24)]
+
This blog looks at using that feature with Groovy.
-The examples in this blog were tested with Groovy 4.0.16 using JDK version
22-ea+27-2262.
-As the JDK version we used is still in early access status,
-you should read the disclaimers to understand that this JDK feature
-is subject to change before final release. If and when the feature becomes
-final, it looks like Groovy will automatically support it without needing
-any additional tweaks.
+Like many JDK enhancements, Groovy provides automatic gatherer support without
needing
+any changes.
+
+The examples in this blog were tested with Groovy 4.0.26. The Gatherer
examples used JDK version 24.0.0, other examples are tested with JDKs 8, 17 and
24.

but it's great to know that with gatherers, we can
likely pick whichever style makes sense.
-We are still in the early days of gatherers being available,
-so expect much more to emerge as this feature becomes more mainstream.
-We look forward to it advancing past preview status.
