I have seen the StackOverflow Insights about Most Loved, Dreaded, and Wanted Languages and I have some questions. If you are not a Java developer or you develop Java but do not like. Please, share the whys! 😃

Yes, I think one of the strengths of Java is the JCP.
If you think that Node.Js has tons of frameworks and you have to learn each framework. With Java, there is no such thing. You learn Jakarta EE and you can use it with Quarkus, JBoss, Thorntail, TomEE, etc... There is a standard. You can switch your implementation almost without pain.
Anyway there are also good things (TM), still you asked for cons only :P
Regarding the Memory Hog...
Ok... you develop C/C++ with Qt! Nice, we have the same background. I developed C for years, start using Java, then starting porting C libraries using JNI.
I think the JVM Memory Management was a nice feature in the past, but Docker killed the necessity for this feature. If we could just delete an object manually will be a great improvement.
When people refer to java as a memory hog, they compare it to other more higher level alternatives then c/c++: Node, Python, Ruby, C# they all consume less memory than java in the same condition. Some do with perf handicaps (Python), still the used ram is way lower.
Also there is a "niche" now days with Go and Rust. Here the memory usage comparison is simply a joke!
About cap'ing memory usage, yes this was a good feature in the 90s but with VMs (way before containers) and a good "single responsibility" approach to ops, java memory cap'ing is obsolete IMHO - also java 8 had some nasty side effects with containerised envs.
Also, why limit max memory but not CPU usage?! you can still put a server on its knees just limiting max RAM! So the feature was nice but also non-complete.
Thanks again, I didn't know the meaning of the word hog. 😏 So I had to assume based on Google Translator.
Thanks! I agree with you.
About the tons of frameworks...
In truth, there is a political game from Pivotal that creates one framework besides the community.
In Java, the community is important and there is a standard for development. Jakarta EE, former Java EE, is the standard. If you implement your application using Jakarta EE you can deploy in any Application Server the implements it. I have already switched from one implementation to another with no changes on my code.
Now Spring is the most used Framework, but it is not a Java standard.
Yes, this is debatable: it is better to have a rather complex standard (Jakarta) once learned used everywhere, or a lot of simple frameworks? I mean: it took me 30 min to understand Vert.x Web, but a lot of CDI/IoC is still black magic to me! Let alone how the hell JPA can amazingly derive SQL queries from methods' manes! that's silly!
Just ditch Java, pray for Kotlin
By an accident I'm turned into a Java(Spring) dev from being a Frontend JS guy. If I skip all the technical thing and only look into the process of learning, finding resource, researching, All I could says is:
Too verbose! I'm not experienced as others here but when I started it, the verbosity of it deterred me from it. Never looked back at it since.
Speaks more, does less. The opposite of Python.
Are you sure?
What do you mean with less? Are you saying that Python is fast? Or are you saying that Python has more functionalities?
My experience has been that in most cases, you have to write more lines of code to get the same thing done. Didn't speak about which one's faster. They can coexist. In some situations Java is better, in some Python is better. And there're several other languages too that compete. There's no perfect language.
Memory hog. Everything is an object.
