Honestly I would consider that a bit weird. At the very least, old-fashioned. If you like Java, it makes me think you haven't tried a better more modern language to compare it with.
It doesn't (usually) come with the Java culture 8 layers of abstraction. This isn't in the Java language. This isn't in OO. Yet nearly every Java programmer makes things way more complicated than it needs to be.
It's a prettier language. Similar syntax with less bullshit.
I only had one job that used C#, and it was the worst job I ever had. Even with the worst possible way to be introduced to the language, I still love it.
Nah, C# suffers from a lot of the same shit Java does. Needing everything to be a class is just no longer a good design choice (if it ever was). AOT support is still lacking. I don't get, why it does not have typdefs. I think the solution / project structure is unnecessary and I could probably think of more stuff I dislike about C#. But imho, it still beats Java.
Golang is my choice over C# any time. I strongly prefer how interfaces are handled and I actually like the error handling.
In 2015 they added scripting. If you're making a real project, you should absolutely use classes. (It's not that hard. Don't do the Java shit.) But you can absolutely write one off scripts just fine.
AOT support is still lacking.
Publishing your app as Native AOT produces an app that's self-contained and that has been ahead-of-time (AOT) compiled to native code. Source.
It's better than Java, but they still chose to walk headfirst into the same trap that bites Java developers in the ass: associating interface implementations with the struct/class rather than the interface itself.
When you have two interfaces that each require you to implement a function with the same name but a different signature, you're in for a bad time featuring an abomination of wrapper types.
Edit: I misread your comment as "like in C#" and wrote this as an answer to the non-existent question of "can't you use explicit interfaces like in C#"
I haven't kept up with recent Java developments, but with Go, you're out of luck. Interface implementations are completely implicit. You don't even have an implements keyword.
Didn't understand my criticisms of Go and Java's interfaces, or do you just enjoy LARPing as a senior programmer while living in a small world where the term "interface" strictly means object-oriented programming and not the broader idea of being a specification describing how systems can interact with each other?
I like how straight-forward the syntax is. And it also seems orderly to have everything be a class. There's a system to it.
I'm using C++ for a project now and I like it in a similar way, but there's more freedom (everything doesn't HAVE to be a class). So with C++ I'll never go back to Java (unless it's for a job).
I don't really like Go either, but it's better than Java, and it's pretty good for Big Software (tm). In the end, every language has some problems. Java just has all of them.
I am a certified Java hater, but you're allowed to like it. If simple and objected oriented is what you want, I can see the attraction, and it has a good and mature ecosystem.
No, Java has lots of merits. For example, once you know layout managers, you can have a resizable GUI app in no time. It's the exact opposite of arranging things pixel by pixel. You just define "I want a grid of these buttons south and a big text field in the center" and Java will do the rest. I whip up apps like this for the silliest things, like noting which dungeon has what rotating boss this week in a game, so it's more convinient than noting it in a text file.
