I haven't worked on a big Java project in a few years, but I would always find myself missing stuff from C#.
For my use cases, Java has all the wrong compromises: - not high level enough to compete with Python/Ruby/JS/PHP, etc - not low level enough to compete with Rust/D/Nim/Zig - not specialized enough to compete with Erlang/R/Go/Julia - not opinionated enough to compete with Lisp/Haskell So why use Java ? It's good, it's fast, it's productive, it's well supported, battle tested and documented for decades with a huge pool…
Interesting - you seem to be saying that Lisp is very opinionated. If that was your intent, may I ask why? Your experience doesn't jibe with my experience as a Common Lisp user, which is that Lisp isn't opinionated enough, and gives you too much flexibility (in some cases).

I also don't understand where is the "fun to write" aspect exactly that the author insists about. "This cannot be understated: Java simply feels good to write" But why? The only explanation that follows is that "a lot of this is due to the craftsmanship JetBrains puts into IntelliJ IDEA. Everything is autocompleted, jump-to-definition is fast, find-usage works well, and refactoring is easy" . I too think that IDEA is…
> I too think that IDEA is an excellent IDE, but why should Java take the credit for it. If anything, the more it needs an excellent IDE in order to feel pleasant, the worse it says about the language itself. It actually does, the language itself makes those features possible. The reason javascript does not have as good IDE is that language itself stands in a way.

> i dont think you need value types at all, and you can simulate it by using byte buffers with an abstraction on top of it. After all, what's the difference between value types and a byte array? The difference is a bit like coding in Java vs coding in assembler (more below in an example). > The only reason java gets poor performance is the coder doing java is too used to producing garbage (or is too inexperienced to…
Having thousand NPC objects around is no problem at all. The rendering part is the only thing critical/numerous enough that you may have to optimize to such a low level.
Also significant game state is not only represented by renderable content.
The ultimate problem with Java (and OOP too, even in the Kay's sense) is that its philosophy represents a very paternalistic approach to software development. The idea is here are these things called objects, you can't look into them, and you only have to use them the way they are designed; under no circumstances you can break them down into internal components and remix those freely. In Java, this overall approach m…
Data classes that expose their internals are a great way for some program logic, but let’s say a database connection is very much not a simple data class. It does have some static data, but it should not be accessible to the outside, because then it is not safe to close/use/whatever.

Could you clarify the point on Android and copyright issues? At least at the time in 2017 when Google blessed Kotlin as an officially supported language, it seemed like the reasoning was Kotlin was far more ergonomic than Java. How does copyright come into this?
Oracle suited Google for copying the APIs (not the implementation) of the Java standard APIs. It all started in 2010 [0] Kotlin was Google's backup if the suit went Oracle's way. [0] https://en.wikipedia.org/wiki/Google_LLC_v._Oracle_America,_... .
Java (and JVM) sure has its advantages. And I enthusiastically advocated it in the nineties, when no one seemed to see its strengths. It was simple, performed well (other than GUI and classloading sometimes took a minute) and was very portable. I even wrote some demos in it in the late nineties to show it can actually do 60 Hz realtime graphics. Over time, the ecosystem got pretty strong. JVM improved and the perform…
And frankly, you simply can’t write all the software in use in low level languages. Yeah, it is theoretically possible but not feasible
I do think Java has a bad rep as a "dry, corporate, enterprise" language, but I think there is an ecosystem around Java that is pretty awesome and you can build incredible applications with Java if you want to. Java has a branding problem. Java (and Oracle) missed the wave of the last 15 years when tech became "cool." If you were new to tech/programming and wanted to pick up a language, which of these three would you…
This is a funny comparison, for sure. What is really going on here is that there isn't a " the Java website". There is no single organisation or project behind Java which could put such up a website. Similarly, where is the C++ website? The C website? java.com was originally the website aimed at end-users who need to install Java to use desktop applications written in Java. It looks like it's from 2010 because that's…

Nobody who has ever written error handling in Go could possibly downvote this comment. Holy moly, the error checking after EVERY interesting method call. Talk about verbose.
It's useful verbosity. Java's verbosity is misplaced, which is worse.
