Is it official now to call the taskbar notification area as 'tray'? I remember Raymond Chen saying that this is wrong 🤔 devblogs.microsoft.com/oldnewthing/...

Fixed a static analysis warning in a Java file in the repo
.

It was a demonstration Java file used to onboard users and teach them about IntelliJ IDEA inspections and quick-fixes. The warning was there to illustrate how inspections work 🤦

TIL: In #Java, List.subList() and List.reversed() are implemented smartly. You may call these methods as many times as you want and in any order, but you don't get a long chain of references which leads to StackOverflowError. The longest chain of views is two: reversed -> subList -> original list.

Implemented Comparator.min/max for the Java standard library. Should be available since Java 26.
❌comp.compare(a, b) >= 0 ? a : b
✅comp.max(a, b)

JetBrains AI Assistant is quite useful for adding Maven dependencies. Take care, though, to update the versions to the latest, as its learning set is somewhat outdated. To update the version, invoke good old code completion.

Yesterday during dinner with Javazone speakers, I asked JetBrains Kineto to create an app to check whether a number is prime and show factors if it's not. It took a single prompt and about 30 minutes. It deploys the app automatically. Now I have my very own prime checker 😁

🤯 Null pointer exceptions are still around – and still costly for developers.

#JSpecify 1.0 is a new player aiming to fix that, with growing support throughout the #Java ecosystem, including in IntelliJ IDEA.

Java 24 is three times bigger than Java 8. That's the fact, that's simple math.

What I see: missing semicolon at line 8.

I like how @briangoetz.bsky.social uses type nullability markers ? and ! in an unrelated discussion without even explaining them, like if it's already well-known thing that exists in the language for a long time 🙂

As named constructors are not possible in #Java, some non-public constructors in OpenJDK contain bogus parameter, just to differentiate them from other constructors.

/*
* Package private constructor. Trailing Void argument is there for
* disambiguating it against other (public) constructors.
*/
String(AbstractStringBuilder asb, Void sig)

I've wanted to buy "100 Java Mistakes..." by @tagir-valeev.bsky.social for a while. Done 👍. Tagir knows so much about Java, and I'm sure I've made many of these mistakes. I'm looking forward to reading this now. 🙏
