Anon tries programming in Java

Anyone who knows me knows that I hate Java with the fire of a thousand suns, but this is just sad. Most of these are true of any programming language. There are plenty of legitimate reasons to hate Java besides the fact that its concurrency utilities are as utterly shite as those of its 90s contemporaries, like the fact that it does not support multiple inheritance, or remote interface implementation, or any form of namespacing besides the goddamned filesystem, or unsigned integers, or string formatting, or

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?

Java

Thats your first mistake bucko

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.

Can anyone who's actually dealt with Java tell me how much Anon is exaggerating?

My inner mathematician respects Java. The first step in any problem is defining your universe

My old boss is one of the 3 initial creators of Java. He ran our department the same way this greentext reads.

He was also a paedo. You can figure out the rest if you dig.

Am I weird for liking Java? I feel like it just makes so much more sense than other languages.

If it took anon 30 minutes to write hello world in java, programming is not for anon.

C# masterrace and I'm tired of pretending it's not

Not using Eclipse helps. Using Scala helps even more

Forgot the JVM eating the entire machine's RAM for breakfast

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

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.

Just imagine how it must have been to code Minecraft 🤣

You're not stuck with it Anon. You can use something different!

I started with java for school. The day I tried C for the first time I was flabbergasted, "what do you mean it doesn't matter which order I put things in?"

This is probably the best 100 second explanation of Java to exist.

Must be several years old - otherwise, javafx deserves quite a bit more ire.

I learned programming with Java and then thankfully never had to use it since CS102. HATRED

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.

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

I still think Java is good for teaching newbies precisely because it will throw an error quickly if they are doing it wrong.

I don't think Lemmy would've let you post a smaller image.

Trying to print hello world is actually pretty easy

public static void main[Args]{ SystemPrintOutLn("Helli world"); }

That's should be it. But I can devinetively agree. For simple tasks Java is to complex because you need to do to much stuff prior to it. If you have more complex things its actually not that bad since if you have a good polished infrastructure it can be quite good.

Threads will literally punch you in the face

Like...through the monitor? How does that work? Is it an actual fist or some kind of mobile computer component?

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

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.

Just use c#
