Could be worse, could be programming Javascript (or Typescript).

This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
- Anon is often crazy.
- Anon is often depressed.
- Anon frequently shares thoughts that are immature, offensive, or incomprehensible.
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

I might have agreed a decade or two ago, when I knew no better. But today, I find the tribalism surrounding programming languages comical.
I don’t particularly like Java, but I use it because it pays the bills. Similarly, I use C++ (which I prefer) when my work requires it.

My experience with Java over the last 2 decades or so. Shame Android gave it extra life, thankfully Kotlin exists now.
Yup, I swore off Android dev almost entirely because of Java, and then Kotlin came out and Android programming was tolerable again. Not fun, tolerable, lipstick can only make a pig so appealing...

If it took anon 30 minutes to write hello world in java, programming is not for anon.
We bow to your wisdom, wise gatekeeper
It's like 5 lines of trivial code
Some of us try to understand what we're doing, rather than just copy/paste. It's easy to discount how difficult learning the basics of something is when you're already past it.
And most IDEs will autogenerate it for you.
That said, I think it highlights everything I hate about Java:
public class MyClass {
Why does it need to be a class? I'm not constructing anything?
public static void main(String[] args) {
Why is this a method? It should be a top-level function. Also, in most cases, I don't care about the arguments, so those should be left out.
System.out.println("Hello world!");
Excuse me, what? Where did System come from, and why does it have an "out" static member? Also, how would I format it if I felt so inclined? So many questions.
And here are examples from languages I prefer:
C:
#include "stdio.h"
Ok, makes sense, I start with nothing.
int main() {
Makes sense that we'd have an entrypoint.
printf("Hello world");
Again, pretty simple.
Python:
print("Hello world")
Ok, Python cheats.
Rust:
fn main() {
Ooh, entrypoint.
println!("Hello world");
I have to understand macros enough to realize this is special, but that's it.
In C, Python, and Rust, complexity starts later, whereas Java shoves it down your throat.

I also think Java is shit, but if you manage to get a NullPointerException while writing a hello world program, maybe anon is just not cut out for computers?
I always loved that Java has a NullPointerException but doesn't have the concept of pointers in the language (only references).
That is because they planed to add pointers and then gave up.
I can't tell if you are making a joke but I can believe it could happen if it's Java
I mean... they have them. And unsafe. You're just not supposed to use them
C# has NullReferenceException and it actually makes sense.
Aside from the general stupidity, Java is a heavily front-loaded language in my experience. I'm not going to engage in any tribalism about it or claim that it's better or worse than others. As a matter of personal taste, I have come to like it, but I had to learn a lot until I reached a level of proficiency where I started considering it usable.
Likewise, there is a level of preparation on the target machines: "Platform-independent" just means you don't have to compile the program itself for different platforms and architectures like you would with C and its kin, as long as the target machines have an appropriate runtime installed.
Libraries and library management is a whole thing in every general-purpose language I've dealt with so far. DSLs get away with including everything domain-specific, but non-specific languages can't possibly cover everything. Again, Java has a steep learning curve for things like Maven - I find it to be powerful for the things I've used it in, but it's a lot to wrap your head around.
It definitely isn't beginner-friendly and I still think my university was wrong to start right into it with the first programming classes. Part of it was the teacher (Technically excellent, didactically atrocious), but it also wasn't a great entry point into programming in general.

Java
Thats your first mistake bucko
