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.

Unchecked Java: Say Goodbye to Checked Exceptions Forever
This is every Lombok lover's favorite strawman argument I've run into.
I've been coding in Java professionally for ~20 years. I can count with zero hands the number of times I've been burned by a getter or setter getting changed into something surprising.
If you really need auto-generated getters/setters/builders - Immutables [1] is a library that does it using bog standard annotation processing rules that don't require hacking your build process.

ExpressiveJava: Re-implementing a simple Scala interpreter in JDK 8/15/17. JDK 17 code nearly identical with use of Records + Pattern Matching + Sealed Types.
That's good, but I prefer this : https://github.com/immutables/immutables It has all sorts of neat stuff like lazy, defered, cached, defaults etc. Just needs updating to use records.

Stop using noargsconstructors and setters (and builders)
Not bad :) I like using Immutables (which is backed by the style of implementation referenced in the link in https://github.com/immutables/immutables/issues/450)

If you could change one thing in the Java and one thing in the JVM, what would you change?
Annotation processors? Like Immutables? Those already exists, but the major difference is that an annotation processor cannot change the processed class, but has to create another one.

Popular technologies for a full-stack Java developer
While you’re looking into this I would highly recommend checking out immutables. https://github.com/immutables/immutables It is pretty popular in the industry and very nice!

ExpressiveJava: Re-implementing a simple Scala interpreter in JDK 8/15/17. JDK 17 code nearly identical with use of Records + Pattern Matching + Sealed Types.
With JDK17 and the introduction of Record types, sealed classes/interfaces, and pattern-matching the implementation can come close to ver-batim mirroring the Scala 2 one: - Scala: https://www.scala-lang.org/old/node/56.html - JDK 17 Java: https://github.com/Randgalt/expressive-java/blob/master/java-17/src/main/java/examples/SimpleInterpreter.java

ExpressiveJava: Rewriting simple Scala interpreter – JDK17 code nearly identical
I wanted to share this little project I found. The author has been writing Java re-implementations of the same Scala interpreter over the years as newer JDK versions & features are released.
With JDK17 and the introduction of Record types, sealed classes/interfaces, and pattern-matching the implementation can come close to ver-batim mirroring the Scala 2 one:

Unfortunately, the Scala org website is down right now, so the original code can be viewed here for the moment:
https://web.archive.org/web/20200103022853/https://www.scala...
(Or also in the repo: https://github.com/Randgalt/expressive-java/blob/master/scal...)
The final feature that is needed to really seal the deal, is part of JEP 405 for destructuring + binding to values in patterns ("Deconstruction patterns"):

Why Co–Star Uses Haskell
using records and ADTs (sealed types) with pattern match "switch" and the net result is an almost verbatim translation.
https://github.com/Randgalt/expressive-java/issues/1
There is one ugly line which JDK18 will fix, "destructuring in pattern captures/match".

JHipster - JHipster, much like Spring initializr, is a generator to create a boilerplate backend application, but also with an integrated front end implementation in React, Vue or Angular. In their own words, it "Is a development platform to quickly generate, develop, & deploy modern web applications & microservice architectures."
