Je suis en train de convertir un projet de #scala vers #java et bien je suis assez agréablement surpris des avancées de #java mais quand même heureusement qu'il y a #vavr https://vavr.io/

@SusanPotter @routis the question was about #java+functional idioms... So #Kotlin is out of context 😅

I love kotlin, I'm even GDE for this specialty, but if the requirement is Java, then we should not advertise for it. #KotlinFatigue

And yes, #VAVR is old and not maintained a lot... But it still exists and works as a lib😇

@davinkevin @SusanPotter

#vavr is / was? an awesome library. Offers Try, Either, Validation, and immutable collections and many more.

I don't think though that it is being actively maintained.

If you want to learn functional programming I suggest to consider #kotlin

Language has great support for immutable data structures (data classes, immutable collections) and in addition there is #arrow-kt library.

The later is a modern and kotlin idiomatic FP library.

@SusanPotter I used #VAVR a lot before switching to #Kotlin.

Inspired by Scala, every useful functional structure should be available

💡Java Exceptions are not my best friend. When I found replacement for it in Either my approach to coding changed drastically. In below post I wanted to share with you my thoughts on why in code it is better to use Etiher approach, and leave Java exceptions for JVM internals.

The VAVR Try monad makes it easy to deal with exceptions in the normal Java flow through return types.

Using pattern matching with sealed interfaces and the vavr Either type to give a much cleaner way to handle errors in a Spring Rest controller https://softwaremill.com/functional-error-handling-with-java-17/

Anything know what's going on with #java #vavr? I love working with it, but there have been no new releases for at least 2 years, it seems stuck in 1.0-alpha.

As much as it makes developing with Java so much more enjoyable, I can't justify using it if it's a dead project.

Maybe the #resilence4j folks know?
