This makes me wonder why most of us use Java at all. In your typical web app project, classes just feel like either:

1) Data structures. This I suspect is a result of ORM's not really being ORM's but actually "Structural Relational Mappers".

- or -

2) Namespaces to dump functions. These are your run-of-the-mill "utils" classes or "service" classes, etc.

The more I work in Java, the more I feel friction between the language, its identity(OO beginning to incorporate functional ideas), and how people write in it.

Java was the first popular language to push static analysis for correctness. It was the "if it compiles, it runs" language of its day, what meant that managers could hire a couple of bad developers by mistake and it wouldn't destroy the entire team's productivity.

I'm not sure that position lasted for even 5 years. But it had a very unique and relevant value proposition at the time.

OCaml would like to have a word with you. In 2005 it already had better static analysis and correctness on object oriented stuff than what Java struggles to approach today.

But Java has better marketing.

A lot of that is down to how people rely on frameworks that force them into "convenient" abstractions. Like Spring and Hibernate. But those are not the language. They represent a (vocal) subset of programmers.

You don't need an ORM or an overgrown dependency injection framework to create a webapp in Java.

Service classes are the thing I hate most. They’re just namespaces for functions. They’re a product of Java not being able to have top level functions.

[elric]

Not being able to have top level functions is a feature, not a bug.

You can declare static methods on interfaces in Java, which means you could call things like Users.create("Foobar") if you wanted to.

They're just namespaces for functions, and... why is that so bad? Of all the reasons I hate Java, this isn't one of them, it's whatever.

The separation of functions and records..

I've read his book "Domain Modeling Made Functional" without much prior knowledge of F#. He provides some compelling examples and some of it ended up inspiring how I write OO code. F# seems cool but it felt like it was close to being extinct.

Java is a waste of time for the reasons you said. People use it for legacy reasons. Back then, the alternatives like JS just weren't there yet in several spaces like backend. Your alternatives were even more cumbersome like C++.

This is so incredibly wrong it must be a troll.
