Java
Thats your first mistake bucko
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
Am I weird for liking Java? I feel like it just makes so much more sense than other languages.
C# is nearly the same, but much, much better.
- 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.
- It’s open source
- It’s still multiplatform. Modern dotnet / C# works on anything.
- Both Visual Studio and Visual Studio code are great IDEs that blow Eclipse out of the water
- It’s one of the most common business languages.
- It’s going to be supported forever.
If I could restrict the world of programming to two languages, it’d be C# and Rust. C# for most things and Rust for a lower level language.
I’ll take Python and Fortran, thank you very much
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.
If it took anon 30 minutes to write hello world in java, programming is not for anon.
We bow to your wisdom, wise gatekeeper
Thank you. If you bothered to read a 5 minutes tutorial instead of posting to 4chan, you could also reach this level of knowledge.
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.
Can anyone who’s actually dealt with Java tell me how much Anon is exaggerating?
Not much at all. It’s truly awful
I’m pretty sure Java doesn’t have pointers, so writing a hello world application isn’t gonna fuck up nearly that hard.
The one thing he forgot though is that your source file is probably in the folder
com/companyname/net/classes/factory/factoryfactory/worker/lib/bin/refresh/jdk/model/ui/closebutton/press.java
And spread out among a bunch of other directories, and the java file is like…3 lines. But there are 10k files spread all around directories like this that are all 3 lines a piece with a class definition.
They have sort of pointers, like references, that can be null…
You just “new” stuff to it and let the “garbage” collector deal with freeing stuff up. When it feels like it.
wait, so when .io gets deregistered, are a load of companies going to have to rename their root directories and rewrite all of their include statements?
Thankfully, despite naming them like that, it doesn’t actually seem to have any real purpose. Apparently they just wanted to make sure that different companies making different libraries didn’t accidentally use the same name for their project…
That’s exactly the reason. And also no company is going through the bother to refactor that shit, so everything is named based on some other company 5 mergers and acquisitions ago.
I’ve worked on a corporate project with multiple Java services, anon isn’t really exaggerating. Java can be a hell scape at times
They forgot to mention that production Java applications apparently need to log a certain minimum number of completely meaningless stacktraces per hour to work properly. Or at least I assume that is the case from the fact that all of them do that.
Best with an old and vulnerable log4j on a Windows log server.
We don’t know what’ll happen if we update. And we don’t know if the dude who coded it will answer our calls. YOLO!
At that point, just kill the VM the app is running on and deal with the fallout.
But none of this is relevant for a hello world program, right?
You would be surprised, errors right out of the box on a freshly initialized project aren’t uncommon
As I’ve been working with Java professionally for years, you’re right, I would be surprised, because that would be really uncommon.
I’ve been programming in Java professionally for 11 years. It’s not just embellishment, it’s outright lying.
Threads giving you race conditions? All concurrent programming will do that if you’re shit at it.
Java has come a long way. I will admit that UI in Java is terrible. I would never do that.
It’s not accurate to accuse Anon of “lying,” when both their story and yours would point to the race conditions from threads being a symptom of someone who’s just learning the language.
It’s not that serious though; because it’s a greentext, it is both artificial AND homosexual.
Java is religiously backwards compatible. Modern java projects are not as enterprisey and boilerplatey, but, as jdk21 is backwards compatible with jdk1.3, you can still happily write code as if it’s 2003.
Additionally, the java space is huge, so just wildly googling will probably not help you that much.
Is that why every single application will only work with some ancient version of Java?(usually 8, sometimes 1.6 or 11)
I can’t think of many cases where Java 21 is a drop in replacement, and I don’t think anyone actually used 17.
Only have a beginner perspective, but in school I did really well in intro CS class that used Python. 2nd class was in Java and it almost broke me I was so confused.
Hated Java in school
But before Java I learned a bit of Pascal and C/C++, and I’m so fucking happy that I’m currently working with C++ in my job and not with fucking Java
I still hate it with everything I’ve got …
I really enjoyed the text.
From the perspective of a python programmer it all seems valid.
A Java-Dev would probably write the same about an embedded engineer.
I still think Java is good for teaching newbies precisely because it will throw an error quickly if they are doing it wrong.
Rust over there like
Hey kid, tired of putting off your problems?
Java is terrible and I hated it but I feel like this stuff is not why, this mostly just seems like stuff that most powerful object oriented languages do.
I’ll never get the hate for java and love for python. It’s like learning mandarin because you think it’s easier than Spanish. When you know java you also kinda know javascript, C, Php, and others. When you know python, it’s probably a government sponsored course, or a programming class talked your school district into buying their “intro to programming python course”. Plus you only get to know python. I’ll die on this hill
Forgot the JVM eating the entire machine’s RAM for breakfast
JVM is like a gas. It expands to fit it’s container, however large that is.
Could be worse, could be programming Javascript (or Typescript).
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.
Tell us more ancient one, your heroic tale of “giving up against the endless weight of capitalism” is fascinating.
“giving up against the endless weight of capitalism”
We just call it “having a job” nowadays
object orientated programming is the wrong idiom for almost all problems, and even in the few cases where it makes sense, you have to be very careful or it’ll hurt you
Hello World
30 minutes of boilerplate
writing imports
$ cat <<EOF > Hello.java public class Hello { public static void main(String args[]) { System.out.println("Hello world!"); } } EOF $ java Hello.java Hello world!ok
This is getting a little better nowadays.
> cat Hello.java void main() { System.out.println("Hello, World!"); } > java --enable-preview Hello.java Hello, World!Things to notice:
- No compilation step.
- No class declaration.
- Main method is not
public static - No
String[] args.
This still uses preview features though. However, like you demonstrated already, compilation is no longer a required step for simplistic programs like this.
Microsoft Java is a one-liner these days.
> cat program.cs Console.WriteLine("Hello, World!"); > dotnet run Hello, World!
C# masterrace and I’m tired of pretending it’s not
C# is nicer Java, but I think it’s still fundamentally a poor language.
Rust master race:
fn main() { println!("Hello world!"); }Unfortunately, the time you save typing you’ll spend compiling, so there’s that…
