Another exciting evening at #JUG Munich! @thjanssen123.bsky.social showed us all the goodies of #Spring AI and how we can integrate it into own applications. It's already production-ready with a lot of potential for future growth. My key takeaways 👇

Excellent overview of Spring Boot Testing principles, tools and best practices by Philip Riecks yesterday in front of #JUG Munich crowd! Years of experience distilled in 90 mins meant a real gift of knowledge in this super important topic for #Java developers.

My key takeaways 👇

This is a complete, valid #Java 25 app. It's powered by JEP 512: Compact Source Files and Instance Main Methods authored by Ron Pressler, Jim Laskey and @gavinbierman.bsky.social. More about JEP 512 👉 openjdk.org/jeps/512

Did you know that #Java 25 brings 18 new features (JEPs), out of which 12 are final, 4 are in Preview state, 1 in Incubator and 1 Experimental? See the full list at openjdk.org/projects/jdk...

More power? .container>(.item$*5) followed by Tab will expand to (🧵 5/6)

Now try it! Open a new HTML file and type div>p>span and press Tab. It expands to these formatted HTML tags: (🧵 4/6)

Now do the same for CSS. Go to Settings -> Editor -> Emmet -> CSS and see if Enable CSS Emmet is checked (🧵 3/6)

First check if the Emmet is turned on. Go to Settings -> Editor -> Emmet -> HTML and see if Enable XML/HTML Emmet and Enable abbreviation preview are checked (🧵 2/6)

GitHub CEO Thomas Dohmke said yesterday that it's important to retain manual coding skills despite #AI boom. I'd add that mastering object-oriented design (OOD) is MORE critical nowadays, not less. Here's why 🧵 (1/6)

Now click on the first row, i.e., on the feature you've used most often. In the pane below you'll see a short description and the keyboard shortcut which activates it. If you don't already know that shortcut, write it down and start using it immediately! 👇 (🧵 4/6)

You'll see four columns with various IntelliJ IDEA features. Click twice on the Used column to sort by the feature you've used most. 👇 (🧵 3/6)

Open it by clicking Help → My Productivity. A new window titled Productivity Guide will open. 👇 (🧵 2/6)

Oh, it works on non-problematic code too - you'll often get a suggestion for refactoring or some other useful operation on it. (🧵 2/2)

💡 The most important keyboard shortcut for #productivity in IntelliJ IDEA is Option+Enter on Mac (Alt+Enter on Windows). See yellow or red highlights in your code? Hit it and @intellijidea.com will very likely offer a correct fix! (🧵 1/2)

Event modelling and event sourcing go best together. You need 5 elements and 4 patterns to implement any system. Generate 80% of the code. Never lose info about what has happened.

All that and more in an excellent talk by @martin.eventmodeling.org in front of JUG München tonight

Another excellent meetup of #JUG Munich! Daniel Schwarz showed us, in his fun-packed way, the most important classes for handling date and time in #Java together with use cases and caveats. And man there are some nasty bugs which could bite us if we don't use the right classes and methods.

Enis Spahi showed us 3 ways of developing and evolving an #API between a client and a server using OpenApi and AsyncApi! #JUG Munich crowd found the talk super useful and I'm sure you will too
