Javaslang
v蕦vr (formerly called Javaslang) is a non-commercial, non-profit object-functional library that runs with Java 8+. It aims to reduce the lines of code and increase code quality. (by vavr-io)

Can I use Scala if my teammates are using Java in a project?
If you want to cut down on code verbosity in Java, I recommend instead looking into using Java 17 (records), and/or the Vavr library (port of some Scala standard library approaches to Java). https://github.com/vavr-io/vavr

Typeclasses explained in Java
If I managed to gain you interest you can take a look at one of the following libraries like cats, scalaz for scala and vavr for java which contain type class definitions and implementations for common types.

What is your favourite Java specific feature that you miss in other languages?
I'm aware not everyone likes it, but vavr has these.

Z: Point-free programming in Java
I would like to see a more fully-functional tool set available in Java itself. (Functors, Applicatives, Monads, Arrows, and more) Vavr is kind of doing that, but also kind of not really. Scala has all of that, and Scala is fun for sure, but it brings in a lot of baggage for interop. (Sometimes that's not a great choice, e.g. for an old legacy project)

Your own custom Spring Data repository
Functional Programming is becoming more and more popular. Spring provides a couple of DSLs for the Kotlin language. For example, the Beans DSL and the Routes DSL allow for a more functional approach toward Spring configuration. On the type side, Vavr (previously Javaslang) is pretty popular in Java, while Kotlin has Arrow.

Java 16 / JDK 16: General Availability
Or perhaps they could implement it like String. String has mutators but they don鈥檛 change the original value. To get the modified one, assign it to another variable. Another example is the collection framework of vavr.

What can I do with Java 1.4?
I made one (Before realizing it'd already been done) to backport newer language features to Java 8 and it was pretty easy to bundle it up as a maven plugin. But going back all the way to 4 will be a notable increase in difficulty. Retrolambda goes to 1.5 but not all the way to 4. You could hypothetically add a layer on top of it to support 1.5 -> 1.4. That or roll a fork of it.
What are some alternatives?
When comparing Javaslang and Functional Java you can also consider the following projects:
jOO位 - jOO位 - The Missing Parts in Java 8 jOO位 improves the JDK libraries in areas where the Expert Group's focus was elsewhere. It adds tuple support, function support, and a lot of additional functionality around sequential Streams. The JDK 8's main efforts (default methods, lambdas, and the Stream API) were focused around maintaining backwards compatibility and implementing a functional API for parallelism.
