It’s been a while since my last technical deep dive, but I’m excited to share my newest article: "How Fast Are Streams Really? A Realistic Look at Performance and When It Matters."

In this article, I dive into the performance trade-offs between hashtag#Java Streams and traditional loops, backed by JMH benchmarks.
The results might surprise you: when does Stream overhead become negligible, and when should you stick with loops?

But beyond chasing nanoseconds, I wanted to raise a deeper question: when do these performance differences actually matter in real-world applications?

Maybe it’s time to rethink where our optimization efforts go — and what principles should guide our design choices.

My latest article, "The Bytecode Chicken-Egg Problem: Breaking the Cycle with a Future-Ready New Class-File API", is a (quite long) write-up of the talk I gave at JUG Karlsruhe a few weeks back.

In the article, I explore the Bytecode ecosystem and discuss the often-overlooked interdependence between the JDK and third-party Bytecode manipulation libraries, highlighting the "chicken-egg" problem.

The second half covers how the OpenJDK team intends to fix the problem by introducing a brand-new Class-file API.

If you're interested in Bytecode, modern API design, and how to actually use the new Class-file API, this one's for you!

Working with native code in Java can be quite a hassle.
Thankfully, #Java 22 introduced a new API to replace JNI by providing a modern, less brittle approach.

After that, it's either about "CRaC" or the current state of the available JDK ecosystem, revisiting an article topic from 2020.

So far, we've looked at 10 of the 15 JEPs of Java 21.
This time, however, let's take a look at "the little things" that aren't represented by a JEP, like API and tool additions.

These features might not be as significant or impactful as the big-picture features.
Nevertheless, we should learn about them, as there's always an interesting change or hidden gem among them.

In my latest article, I take a look at some of these features that caught my attention.

Localization is an important step for any app to reach a broader market and be more inclusive.

So far, it felt like a chore in Xcode, with no obvious workflow or integrated tools that help you out more than the bare minimum.
But no more, Xcode 15 introduced a new and easy-to-use way for handling localization: String Catalogs.

Even without actually localizing your app, it helps you to aggregate your String into a single place for things like simpler proof-reading.

Not every #Java 21 feature is about introducing new language additions or awesome new APIs for immediate consumption.

A more technical new feature was adding generations to the Z Garbage Collector to make it even better!

Check out the details about ZGC and a way too wordy introduction about GC 🚮 in general in my latest article!

Time for another #Java 21 article!

Pattern matching already got a big upgrade in Java 21 in the form of switch pattern matching.
But now, even Records can benefit!

Let's take a quick look at another preview feature of the upcoming JDK release: Record Patterns.

Not everything a new #Java version release changes are additions.

Let's take a look at the two features that Java 21 will deprecate or at least prepare for removal.

Back from my houseboat vacation on the Mecklenburg Lake Plateau!

I fell off during docking at a marina, which was embarrassing and resulted in some bruises and cuts, and I kinda fucked up my left arm as it caught my full weight to stop the fall 😕

Nevertheless, it was a fun vacation with great weather ☀️

Time for another Java 21 article!

The switch statement has received improvements before, like making it usable as an expression in Java 14.
But Java 21 introduces numerous new features that make it even more versatile: Pattern Matching.
