Slightly tangential, but due to a new job I'll have bite the bullet and learn Java. When googling tutorials, I see the same material I found 12 years ago. A lot must have happened since then. What's a good resource to learn Java for somebody who already knows how to program? I'm interested in ecosystem, tooling, best practices, common pitfalls etc.

Everything is OpenJDK now, forget oracle. AWS put out LTS JRE's etc. Try and get your employer to pay for a jetbrains IDE, IntelliJ IDEA. Use Maven for builds. It's simple-ish. Use Spring for frameworks. Everything's been done so you wont be first with any problems here. And all the stuff from 12 years ago is probably what people know and do, so it's still on point. No one does inheritance anymore composition's all t…

Java might be the most successful programming language. It is a solid choice among many different fields. It is used on huge infrastructure projects (Apache Foundation), governments, big tech companies such as amazon, ibm, google, apple for many large scale services. It can do web, ml, GUIs, it's still strong among academics. On top of that it offers a great programming experience with excellent IDE support and it's…

Ironically, while Java was the original "write once, run anywhere" language, it never succeeded in that regard (e.g. browser applets were never popular). Ironically, I believe Javascript has. I was pretty much exclusively a Java programmer for the first decade and a half of my career, before moving to Node and TypeScript. I don't think I could ever go back at the point. Most importantly, this is my first time where t…

> Java was the original "write once, run anywhere" language That crown properly belongs to the UCSD P-System, which was the Java of the 1980's. It was the same idea as Java - compilation to a bytecode which an interpreter ran. It failed because the interpreter performance penalty was too high. Java also started out as an interpreter, which made it too slow. Steve Russell of Symantec invented a JIT for it, and like th…

Actually BEAM and Erlang pre-dates Java. ;-) As for compatibility: why is Java 8 market share so high in 2020?

Shitty Android.

I don't know about that. I coded in UCSD-P quite a bit (and played a few games written in it, Wizardry on the Apple 2 anyone?). But UCSD-Pascal never reached a tiny fraction of the audience that Turbo Pascal did.
