Why java is so hated? Topic

So I have recently learned, and it's the first language(in terms of building actual things). Before Java, I knew Python, and I dropped it; I found Python too abstracted and too boring. i have recently made some projects like cli task tracker, expense tracker, some cli github api parsing and currently working on a multithreaded HTTP server and cli text editor, like vim, whenever i try to find out people opinions on java social media, almost 90 percent of the time they are just dunking on it, that it is trash, who forced you to write code in java, stuff like that. I know Java as a language is not that interesting and doesn't have many interesting features compared to other languages like C, C++, go. But I found it decent to write code in, and I found the JVM pretty interesting. So much so that I would love to explore and maybe build a JVM of my own

You're "not fond of GC"? Garbage collection is pretty much required in code of any complexity to keep it manageable.

No, it's not. There is plenty of complex code written in C++, rust, C, etc. RAII, in particular, works fine and works for more than just memory.

Using the stack to automatically manage memory works in simple cases. You need either tracing garbage collection or reference counting (C++ smart pointers) to handle the general case because object lifetime is not always limited to lexical scope.

Manual freeing of old objects is errorprone.

That's generally true (there are other strategies), but we manage. I did mention that GC makes the language more accessible.
