#javadev — Public Fediverse posts

Switching from Eclipse to IntelliJ IDEA Community for my Java projects
➡️ smoother UX, sharp code completion, and it's free & open source...

👇 Team full IDE, minimalist editor or "give me just a terminal" (Vim) ?

Hello fellow Java devs.

I'm looking to move away from the Eclipse IDE. The requirements are that I can natively debug in the IDE, it runs on Linux and supports maven out of the box.

While I prefer to use FOSS, I would also be willing to purchase a license, if it is truly an outstanding product.

Does anyone have any suggestions?

ApproveJ 1.5.0 is here! 🚀

Stop writing manual assertions for complex data. Our #JVM approval testing library just got a huge update:

📸 Visual Testing: Approve screenshots (Playwright/Selenium) with pHash.
🗄️ DB Testing: Approve SQL results as Markdown tables.

Passwordless login is one of the simplest ways to improve security and UX.

In this tutorial I show how to build magic link authentication with Quarkus and Keycloak.
Email token → validation → secure session.

No passwords. No complexity. Just clean Java.

And what about code you don't own?

We added @ImportOptics so you aren't stuck. You can generate type-safe navigators for JDK classes, Jackson nodes, or any external library.

It analyses the bytecode to build lenses for you, meaning you can traverse deep into java.time or legacy objects just as easily as your own records.

Just published something festive for Java devs 🎄

I built a Christmas Card Generator using Quarkus Renarde, turning HTML/CSS into crisp PNG images on the server.
No Java2D. No PDFs. Just clean, modern Java.

A fun holiday project that also teaches practical HTML→PNG rendering with Quarkus.

New tutorial on The Main Thread!

Ever had a demo break because an internal API changed overnight?
Yeah… me too.

Today’s article shows how to build Stripe-style API versioning in Quarkus — using date-based versions, adapters, and a clean canonical model.

Perfect for Java devs who want zero-breakage API evolution.

Just shipped a new deep-dive on something every Java dev with a messy repo needs:

A fully automated monorepo workflow for 50+ Java/Quarkus projects.
Dynamic build matrix. Automatic JDK detection. Per-project https://Shields.io badges.
And a README that updates itself. Zero manual CI maintenance.

☕ Java’s AI ecosystem has grown up.
What felt clunky a year ago is now slick. With tools like Spring AI and LangChain4j, building AI in Java is no longer experimental—it’s production-ready. #JavaDev #AI

🚀 Just built custom Ollama models in Java (Qwen3 + LLaMA 3.2:1.7B) — and things got chaotic 😅
Live coding, broken prompts, wrongful victories, and some real lessons for #JavaDev + #AI.
🧵 Here’s what went down (and I need your help for what’s next) 👇

Part 7 of our AI game development series is live — more about exploring ideas together than ticking off a checklist.

#AI #GameDev #LLM #JavaDev

Also, I spent way too much time on tiny refactors again.
Necessary stuff, but honestly? Boring on stream.
I’ll move future refactors off-camera to focus more on the fun AI parts.

Next time I’ll come prepared with a new image strategy and a tighter focus.
Until then: thanks to everyone who dropped by!

Using new Optics support in #higher-kinded-j is easy, just add a simple annotation to automatically generate Lenses, Prisms, and Isomorphisms then compose lenses for incredibly readable, deep updates:

// Create a "shortcut" lens by composing others
var userToStreetName = UserLenses.address()
.andThen(AddressLenses.street())
.andThen(StreetLenses.name());

// Perform the deep update in a single line
User updatedUser = userToStreetName.set("New Street", user);

You can perform effectful operations (failable, async, stateful). The library is also fully extensible, allowing you to define custom Traversal instances for any data structure.

Check out the docs, with loads of examples to get you started!

Power up your functional programming in Java! 🚀
The new Optics support in #higher-kinded-j is here, built directly on our powerful Higher-Kinded Types simulation. This brings a new level of abstraction and power to your code, not just cleaner data access.

Add a simple annotation, and get automatically generated Lenses, Prisms, Isomorphisms and Traversals.

🔧 Why it's a game-changer:

- Built on HKT: Unlocks powerful, abstract, and effectful operations.
- Zero-Boilerplate: Annotation-based generation of powerful tools.
- Extensible & Composable: A flexible foundation for your data manipulation needs.

Why use Java for an AI game?
✅ Full control
✅ Local-first (Ollama)
✅ Spring + Vaadin = powerful combo
