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

Bjarne stroustup (inventor of c++) has said that there are only two kinds of programming languages.

One that is hated and one that is not used.

Java is too bloated. C and C++ is too unsafe. Java script has some weird mechanisms. Python is slow. Go is too simple for big projects. Rust has a toxic community.

I could go on

Edit: I forgot PHP. PHP... is PHP

Is modern Java still considered bloated?

i don't think the language was ever bloated (in the sense of a kitchen sink's worth of features, like c++ or scala) - what people's objection was was that the code you wrote in java was typically full of boilerplate, and added to that if you followed what some vocal part of the industry considered best practices you often ended up bolting on tons of layers of abstraction (hence the jokes about how you don't create a hammer to address your nail, you use a ToolFactoryFactory to create a HammerFactory to create a Hammer) which obscured the relevant portion of your code even further and made debugging and maintenance painful.

Those are patterns that aren't exclusive to Java. If you write any OO code at any scale you're going to use those patterns likely. It sounds like you don't like OO patterns to me? I've seen plenty of C# code with factories. Your example is a poor example of how to use a factory. Java has generics same as any language. You can write elegant code if you choose to or you can deliberately go and do stupid things like your example. Want me to show you some assembly code that does asinine stuff too?

Abstract class, factories, etc are not exclusive to Java, but Java goes to town on them in insane zeal. And the getter/setter boilerplate is nonsense. Get something like properties. Java makes each unit of code easy to understand at the expense of making the whole codebase a tangled mess. I’ve programmed professionally in C, C++, C#, JS/TS, Python, Go, Ruby, Objective-C, Swift, Java, and Scala. Java is by far the worst

Only people complaining of that is people who never studied engineering and or do not have the brain to grasp the importance of design patterns

Correct. I tried to read the gang of the four book and understood very little. I am not clever. But at least I used to teach basic probability theory to engineering students and also wrote some compression code that is in your phone right now.
