My inner mathematician respects Java. The first step in any problem is defining your universe
I still think Java is good for teaching newbies precisely because it will throw an error quickly if they are doing it wrong.
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
I got the impression they skipped the hello world cause it was too easy and they wanted to get right to writing their app, so they moved on to more advanced stuff without having a real grasp of the basics
Welcome to java, we have a couple unconventional ways of doing things, but overall I’m like every other mainstream oo language.
People: AHH! Scary!
Welcome to python. your knowledge of me wont help you elsewhere as my syntax is purposefully obtuse and unique. Forget about semicolons, one missed space and your code is as worthless as you after learning this language.
People: Hello based department
Oh my god I got fucked by a python script once because of a single space. It took forever to figure out what went wrong
Python has its drawbacks but it also has a pretty useful standard library so as a language for small scripts, one can do much worse
It is possible to dislike both. For me SmallTalk-like languages are peak. Message passing for life!
He types REALLY slow.
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.
As embedded dev, the stack trace alone scares me. It would be funny to watch the Java runtime blow the 8 frame deep stack on a PIC18 tho
Sorry, you had a small error in the spacings of your post; Therefore I cannot parse a thing you’re saying. Didn’t mean to scare you with a semicolon either. It’s just a tool in language’s to end a clause and begin a related, independent clause. That could be useful somewhere…
Must be several years old - otherwise, javafx deserves quite a bit more ire.
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.
I’m not a Java dev, but I know enough of it to fix simple bugs in the backends I work with. My main issue with it is that 99% of the code doesn’t seem to do anything. The clear, obvious place that looks like it handles the feature you’re looking for? None of it does anything! It just instantiates another class from God knows where to actually do the work. I swear I spend most of my time in Java projects just looking for the damn implementation in a sea of AbstractSingletonFactoryBean shit.
I’m sorry just as a matter of policy I’m going to have to downvote you for saying you like java. Nothing personal.
I think some things that were novel when java came out are such old hat at this point the 1990s benefits just aren’t benefits anymore. Run anywhere? I’m in a html app right now. As is my IDE and my chat app. Strong interfaces and sane types are only in comparison to the bizarroland of c++ which visibly always seems to basically be word vomit. JIT compilation is in python which is both easier to use and has way better tooling and libraries…making python today run in the “fast enough” category that java was kinda in. I’ve literally never seen a usable java UI tho.
So you’re going to stride past the part where I say “I’m not going to […] claim that it’s better or worse than others”, ignore the bulk of my comment on Java being hard to get into, make a point of declaring you’ll downvote for stating a personal opinion, then pretend it’s “nothing personal”? I’d be curious how that makes sense in your mind.
Anyway, like I said, I see no point in petty tribalism. I like Python and C too - that’s not mutually exclusive. I hope you have a pleasant, Java-less day :)
Minecraft is a decent example of a good java program. People jump to the first silly reason to disregard it. Cope.
Python and Java are barely comparable. I adore both languages equally and use them about the same amount at work. They are just different tools better suited to different tasks.
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
My experience with Java over the last 2 decades or so. Shame Android gave it extra life, thankfully Kotlin exists now.
I’m sure that’s Fireship, without clicking the link.
Nah it’s not you should check it out
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.

I mean, anon is not arguing against that. They’re saying the language is shit regardless of how much it is used in business. I don’t think they are entirely wrong.
Tell us more ancient one, your heroic tale of “giving up against the endless weight of capitalism” is fascinating.
Love the dramatics.
This ancient one has learned the art of pragmatism. A little time in the trenches of enterprise development can do that – turn passionate ideals into practical choices.
Some days it’s C++, some days it’s Java, Python and so on. In the end, the code compiles, and the ancient one get paid.
“giving up against the endless weight of capitalism”
We just call it “having a job” nowadays
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.
Don’t be mad, you’re the one that commented lol. It’s like you’re choosing to be upset
I thanked you for your reply and suggested reading a tutorial. How does that make me mad and upset? You’re acting weird.
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.
C# masterrace and I’m tired of pretending it’s not
After close to two decades of programming, C# is still the best language I’ve used. While some of the newer features seem a bit weird, I’d say it’s one of the few languages that has never got in the way and has just let me write code that made sense. Even with all the improvements Java has made over the years it’s still nowhere near as good as what C# was like maybe 15 years ago.
The same goes for everyone’s other “fav” language, Python. Ruby has been a better beginner scripting language than Python for many years, and while Rails is definitely a ghetto, as a language Ruby is great at teaching great programming fundamentals.
C# is pretty good generally - I know it far better than any other and it pays my bills! - but it certainly has its weak points. Particularly around the newer features, a lot of them feel really rushed and just kind of shitty.
The one I hate the most is the whole “nullable” pattern. It’s a total mess. Having to mark up files as
nullable enable, having to mark methods with a bunch of attributes, and the way that it works differently if it’s a value type or a reference type, it’s just so half-baked.If you spend some time with a more modern language like Rust or Swift then you’ll quickly start to notice C#’s weaknesses.
I feel like you’re doing something wrong with the nullables… I’m pretty sure you don’t need to mark up files, you can just enable it on the whole project? I’m not sure about the attributes, you might have a point there, but it just makes sense for value vs reference types IMO, since value types are already implicitly different in terms of nullability.
But yeah, I can imagine it’s half-baked, since nullable reference types (that’s the name, previously reference types were just nullable by default with no extra features) are a more recent addition to the language, one that wasn’t built with them in mind.
C# has had string interpolation for, what - nearly a decade, now? It arrived with C# v6, which was released in 2015.
Meanwhile Java just pulled their implementation out of the latest beta earlier this year because they couldn’t get it to work right.
Don’t know about you, but I think that Java is largely resting on its laurels as of late. That the only real reason to go for it is it’s third-party library system, and not much more.
Not using Eclipse helps. Using Scala helps even more
Really want to go to La Scala one day but I looked it up and the tickets are like 500 euros. An eclipse is much cheaper
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).
C# has
NullReferenceExceptionand it actually makes sense.That is because they planed to add pointers and then gave up.
I mean… they have them. And
unsafe. You’re just not supposed to use themI can’t tell if you are making a joke but I can believe it could happen if it’s Java
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.
Known for : the Java programming language, internet sex crime and the fantasy defense.
It’s written pedo. I don’t know where the “paedo” thing came from.
Confidently incorrect.
From PIE root “pau-” (few, little), to Latin-transliterated via Greek “paed” (boy, child), and spelled thusly to distinguish from “ped-” (foot), circa 1600AD. Reduced to “pedo” from “paedo” as part of the shift in Americanization of accents and spelling in the late 1700s early 1800s.
Are you saying OP is…
No.
Java
Thats your first mistake bucko
