Did you know you can't really install Open JDK? Open JDK is an implementation of the #Java Platform Standard Edition (Java SE) and distributions like Eclipse Temurin, Azul Zulu, Amazon Corretto etc. are binary builds of Open JDK + some vendor specific stuff.

What day is it today? It's #Java 25 release day! Also it's 16.09.2025 so 16+9=25 and the 2025 ends with 25. Coincidence? I don't think so 😀

Beware when asking #AI to explain some #Java snippet or concept. Sometimes it will give you a confident answer with a detailed explanation which sounds plausible but is completely or subtly wrong.

Typically they overuse Strings, often in a specific format like first_second or first/second and then parse from and to such strings in multiple places. Even worse, there are methods which accept 4-5 params, all Strings and doubles. It's easy to be confused which string represents which concept.

I don't have the proof (yet), just my feeling that it's easier for AI to grasp concepts when they're explicit in the code. Such classes tend to be fairly small with just a few methods. Yes, there's a possibility to overdo it but most repos I've seen have underdid it.

And this is just scratching the surface! Emmet is a time saver. Invest just 15-20 minutes and it'll give you back in multiples. (🧵 6/6)

Even as #Java developers sometimes we have to write front-end code. Did you know you can write HTML and CSS super fast in @intellijidea.com? The secret is IDEA's built-in support for Emmet which can turn 20-30 characters you type into 10x more HTML. This is how you can use it (🧵 1/6)
