Eclipse 2024-03 now available - STRING TEMPLATES !!

The new Eclipse has been release. Expect the JDK-22 to follow any day now.

FINALLY this Eclipse supports String templates as a "preview feature" which you have to enable in the preferences if you want to use. Templates was originally released in JDK-21 as a preview but Eclipse didn't support it until now.

I took a quick look online, is the main goal of string templates to provide an alternative to String concatenation using the + sign?

Check out the Motivation on the related JEP.

Interestingly, it let me use Structured Concurrency classes without checking the "Enable Preview Features" box in the project's properties. Not even a warning. Although it might have been different if I'd tried running the compiled code outside Eclipse, I suppose.

Good stuff. Seems like it should make for some streamlined code where applicable

I feel compelled to observe that IntelliJ has been supporting string templates for a while now.  And it correctly errors out if you use preview features without having the appropriate flags set, with a helpful message for how to set them.

Perhaps because that's not a language feature but an API feature?

Perhaps - but from the command line, I get an error like this:
