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.

Java 21: The Nice, the Meh, and the Momentous
It is not. Blocking IO (with some exceptions mentioned in the JEP) will automatically be translated by the runtime into non-blocking IO when it occurs on virtual threads, and no OS threads will be blocked. You can have a million threads blocking on a million sockets (obviously without creating a million OS threads): https://github.com/ebarlas/project-loom-c5m
You can't do that with thread pools. You could achieve that scalability with async code, but then observability tools will not be able to track the IO operations and who initiated them, but with virtual threads you'll see exactly what business operation is doing what IO and why.

Donβt call it a comeback: Why Java is still champ
That might change in JDK 21 (with virtual threads). See this https://github.com/ebarlas/project-loom-c5m . It achieve 5 million persistent connections (again depends on the server capacity and kernal tuning) using normal simple blocking code (https://github.com/ebarlas/project-loom-c5m/blob/main/src/main/java/loomtest/EchoServer.java) . It's a far better better programming model compared to JS async/await.

Consuming and Testing third party API's using Spring Webclient
The above class maps the json data to a java object we can work with. We use Lombok to generate constructors, getters and setters for our code and the Jackson Project to handle serialization and deserialization of json to pojo . We know the response is an array of objects representing the coffee and so above data structure is fit for this.

π» 7 Open-Source DevTools That Save Time You Didn't Know to Exist βπ
Almost a decade ago, I started reducing my boilerplate (and saving time with Lombok. It made my life much easier, simple as that. Ever since I've been looking into finding the smoothest solutions for saving time rather than handling all of it myself.

How to prevent NullPointerExceptions in Java
Lombok is a widely used library that simplifies Java code. The @NonNull annotation helps enforce non-null parameters, generating appropriate null checks:

Feedback on a new annotation processor api
I gotta agree with /u/rzwitserloot I don't see anything in the lombok repo that indicates they have their "own compiler". I see the "reaching into javac internals" but that's it.

Does any tooling exist for Java to add @NotNull to every parameter, return type, field, etc. by default?
i looked into that and found this: https://github.com/projectlombok/lombok/issues/2310

Would this OpenJDK proposal make Java easier to learn?
Funny enough; /u/rzwitserloot is the author of Lombok, one of the most widely used Java libraries in the world. So it's not really some kind of random-ass Redditor they're having a discussion with either.

Kotlin : A Java developer's perspective
This removes the need to add the 'Project Lombok' library (and going through a phase of installing it in your Eclipse IDE; old school devs know what I am talking about) and speeds up development time. Java 14 added a new feature of 'Records' which allows you to do the same, but it doesn't offer a 'copy' method to ease your object creation and also enforces the 'final' keyword for variables making them immutable.

X-Pipe - A connection manager and remote file explorer. Let me know what you think!
I get the main criticisms of Java, i.e. its verbosity and the requirement for a lot of boilerplate code, and understand why some people switched to Kotlin. But by using libraries such as lombok you can get rid of most of it and suddenly the incentives for switching aren't that big anymore. And in the end it's all JVM bytecode anyways.

How often do you do/use this in your job?
I usually use this... https://projectlombok.org/
What are some alternatives?
jvm-tail-recursion - Optimizer library for tail recursive calls in Java bytecode
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."
remove-recursion-inspection - Intellij IDEA inspection for automatic recursion detection and removal
Immutables - Annotation processor to create immutable objects and builders. Feels like Guava's immutable collections but for regular value objects. JSON, Jackson, Gson, JAX-RS integrations included
remove-recursion-insp
manifold - Manifold is a Java compiler plugin, its features include Metaprogramming, Properties, Extension Methods, Operator Overloading, Templates, a Preprocessor, and more.
Reactive Streams - Reactive Streams Specification for the JVM
Auto - A collection of source code generators for Java.
qbicc - Experimental static compiler for Java programs.
record-builder - Record builder generator for Java records
project-loom-comparison - A comparison of different methods for achieving scalable concurrency in Java
