Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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.

Best Functional Library for Java ? And do you recommend going for a functional style in Java?
https://github.com/vavr-io/vavr/releases showed Vavr 0.10.4 from July 2021 as latest release. 🤷

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’t change the original value. To get the modified one, assign it to another variable. Another example is the collection framework of vavr.

Advent of Code and Dash API Browser
Each year when I do the Advent of Code challenge I use it as an opportunity to learn a new language or tool chain. This year I am writing in Java 17 (I have not used Java since Java 8), along with Eclipse Collections, and using VS Code as my IDE.

New candidate JEP: 431: Sequenced Collections
If you want design like that, you can just use Eclipse Collections (https://www.eclipse.org/collections/). But do note that that design has its own problems if you are after perfection.

Java Bad!
You were a little wrong, surely you can see that? And for Collections that don't autobox, you want to use something like https://github.com/eclipse/eclipse-collections
What are some alternatives?
Functional Java - Backport of Java 8's lambda expressions to Java 7, 6 and 5
fastutil - fastutil extends the Java™ Collections Framework by providing type-specific maps, sets, lists and queues.
jOOλ - jOOλ - The Missing Parts in Java 8 jOOλ 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.
