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:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

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

[–] [email protected] 7 points 1 day ago (3 children)

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.

[–] [email protected] 1 points 18 hours ago (1 children)

Which would you suggest? (And if you say python, I will attack you with a pointed stick)

[–] [email protected] 1 points 18 hours ago

Definitely not Python. Rust is very nice though.

I thought I like Java until I tried Kotlin. It's everything I liked about Java, but with everything wrong with it fixed.

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).

[–] [email protected] 19 points 1 day ago (1 children)

No. Every language has its haters. There's a reason Java is so widely used. If you like it, keep at it.

[–] [email protected] 19 points 1 day ago (3 children)

Yes and the reason is because millions of lines of production code were written and it isn't worth rewriting them.

Plenty of languages around now that don't have 30 years of baggage and the specter of Oracle hanging over it.

Now a days many businesses choose Go.

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

[–] kitnaht 79 points 1 day ago* (last edited 1 day ago) (5 children)

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.

Everything in Java is a hidden pointer

95% exaggeration. Here is reality:

  • yeah you need main class coz it’s OO-language. Though, not required anymore, which should’ve been done once Java got scrip language capabilities (jshell) back in JDK 9. But as of today not required anymore
  • imports exist in most if not all languages. Gotta be insane writing them manually in 2010 let alone 2024
  • installing Java runtime (JRE) is as simple as installing any app. Though for installing JDK you need 5 mins for setting PATH. Think about JDK as like TSC or Webpack and JRE as a Browser. I’d argue installing and configuring JDK is simpler than TSC or Webpack
  • Unless you doing some non-trivial multi-threading your stack trace will tell you exactly where is your NPE. You gotta be as blind as my teammates to spend more than 1 minutes to find where it is coz it literally tells you file and line numer where Exception occurred
  • I mean, yeah if you use IDE from 2000 it will look like it. IntelliJ looks modern, though I don’t like the fact latest versions look like VSCode
  • I hardly reach 3G of deps from all 10 projects I have on my workstation.
  • IDK what anon means by ecosystem here, Java ecosystem is quite standard across the board. JDK(std lib), Maven/Gradle(deps, build, publishing), Spring Framework (all sorts of blueprints and solutions to standard app level problems), Hibernate/JPA (ORM), JUnit+Mockito (testing). These are tools and libs used in 90% of projects I worked on. Of course there will be more depending on project needs. Layers? It’s not like language imposes any layers whatsoever. It’s just common practice to have 3-4 layers and some glue in-between.
  • don’t do GUI in Java it sucks and will suck until Java gets string interpolation. Hopefully soon
  • concurrency is actually the only thing which is really bloated in Java. Which will change with next LTS version if I remember correctly. And it’s not that hard if you actually read the f manual and not just “try and hope”. Again it will become much more efficient and easier to follow soon. As of now - yeah, not trivial. But people mostly prematurely optimize, so karma
  • Java is kinda have 20 ways to do same thing but actually no. Java built with idea of providing simple building blocks. Then it provides more specific API built on top of those building blocks. It allows to have API which solves typical problems and provides capability to solve custom problems with those building blocks. People often confuse this as many ways to do one thing but it’s like saying “I can have byte array why I need string data type”. Those are different levels of abstraction

Edit: typos

95% exaggeration if he is a real programmer.

If he just tried to walk into Java knowing nothing or maybe PHP, and refused to RTFA, he might experience about 30% to 40% of that I just trying to do everything wrong.

  • a hello world doesn't need libraries in Java
  • installing JDK takes at most 5 steps, depending on the OS
  • a nullpointerexception is more likely the developper's fault (unassigned value, calling a function on a null object)
  • IntelliJ is easy to install and modern (granted, other IDEs are very ancient)
  • developping GUI apps is a PITA, no matter the ecosystem (generally)

The rest is more or less spot on (no idea about concurrency issues though)

[–] Blue_Morpho 28 points 1 day ago (2 children)

nullpointerexception is more likely the developper's fault

Of course it was the developer's fault. But it's absurd a language without pointers throws an error about pointers.

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.

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.

It's much better today, but in 2010 that was 100% accurate.

That being said, using Java as a first time programming language is like a 15 year old trying to fly an airliner to get a few blocks away to pick up some after school snacks. Obviously it's way overkill. Sure you could get across town with it, but it's probably 1000x more complicated than just a simple bicycle or even walking.

Java is industrial strength for professionals. There's absolutely no consideration made for educational usage.

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.

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

They only had to deal with LWJGL. The corporate java world has to use Spring.

Edit: They also had to deal with all the fans saying they should've written it in C#.

[–] [email protected] 6 points 1 day ago (2 children)

And much of the confusion and frustration at "Java" is actually because of Spring, or the "enterprise" nonsense making everything unnecessarily complex. You can just... write Java without any of that.

You shouldn't though, because Kotlin exists, which fixes everything that's wrong with Java while still being 100% compatible, so even in legacy projects you can mix and match and write new code in Kotlin without needing to rewrite any of the existing Java.
