🔥 Für Kurzentschlossene: @jugch Talk, heute Abend in St. Gallen 🔥

🧐 Java-Streams wirken elegant – werden in der Praxis aber oft komplex, schwer lesbar und ineffizient.

Heute Abend zeigt Senior Software Engineer @martinfrancois, wie moderne Stream-Techniken zu klarerem Code und besserer Performance führen – aus realen Java-Codebases.

Are you using parallelStream() without profiling? Or still writing Collectors.toList() manually? #JavaStreams have evolved—Mihaela Gheorghe-Roman breaks down what modern #Java offers you from 8 to 24: https://javapro.io/2025/11/13/java-streams-evolution-from-java-8-to-today/

#JavaStreams changed how we process collections—but the API didn’t stop at map() and reduce(). From dropWhile() to Stream.transform(), Mihaela Gheorghe-Roman walks through the milestones you likely missed.

Still writing verbose loops in #Java? Streams have evolved far beyond map() & filter()—from takeWhile() to mapMulti() to gather(). Mihaela Gheorghe-Roman traces the full journey from Java 8 to 24.

🚀 Java 24 bringt die neuen Stream Gatherers – ein Upgrade, das funktionales Java auf ein neues Level hebt.

Gatherers füllen eine Lücke bei den Intermediate-Operations:
✔ eleganter
✔ wiederverwendbar
✔ parallelisierbar

Im Blog erklärt David anhand eines Beispiels:
🔹 wie Gatherers funktionieren
🔹 wie man eigene schreibt
🔹 und warum sie ein echter Gamechanger sind.

Think twice before using parallel streams in a multi-threaded environment! 🧵 #JavaStreams #Performance

Today's experiment was a real eye-opener. 🕵️‍♂️ Comparing loops, streams, and parallel streams. Loops and regular streams crossed the finish line hand in hand. 🏁 But Parallel streams use a common ForkJoinPool, and they're limited by the number of available CPU cores. 🖥️ In server environments where cores are often limited, this becomes a bottleneck. #DevTips #JavaBackend

Java Streams: Behavioral Parameters with Side-Effects

Will the peek operation print the Fibonacci sequence till 5?

"""
Stream.of(1, 1, 2, 3, 5)
.peek(System.out::println)
.count()
