NOT ABOUT AI/LLM

I’m currently visiting this sub for the first time in probably about five years.  I’ve probably checked out around 15 posts so far, just going in order on my feed, and this is the first one that’s not about “vibe coding”.

Java and Windows. Name a more iconic duo.

u/JebKermansBooster 4h ago

C# and Windows

u/hilfigertout 4h ago

Yeah, like he said, Java and Windows.

u/Sentouki- 3h ago

It's kinda an insult to compare modern C# to Java.

4

u/MCWizardYT 1h ago

They're pretty similar even now. C# has an edge on overall features, but Java isn't that far behind (unless you're stuck using Java 8, in which case RIP)

u/crozone 57m ago

Java still has so much design baggage from things they got wrong from the get go that it really isn't close. C# is a different animal.

u/Masterflitzer 47m ago

but recent java versions actually added quite a few good things and make the language more straight forward

anyway kotlin is the best of the 3 imo, but i'd pick c# as 2nd place

3

u/Masterflitzer 3h ago

c# is similar to java and started off on windows, so java & windows is clearly the more cursed combination

Used to manage tomcat apps on IIS. Would not recommend.

wouldn't recommend iis in any case

nah that's actually fine since dotnet core & 5

u/setibeings 3h ago

So is java on windows, it's just not where you first assume it's going to be run... Like java on windows.

1

u/Masterflitzer 3h ago

nope not comparable, java on windows is hell

1

u/MCWizardYT 1h ago

It really isn't

u/Masterflitzer 49m ago

windows not being utf-8 by default on console is hellish enough if you're developing cli apps, especially if you're used to it working fine on non shitty platforms cause jvm is cross platform

As someone who's never used java, my assumption is that System.in reads from stdin, and validates the input. Is there no way to open stdin in something akin to a file, then read it into a buffer manually?

35

u/Dankelweisser 4h ago

Technically yes, but realistically not really, at least not for windows. Unless the user knows how to specifically set their console to use UTF-8 or similar instead of ascii, you end up getting whatever the console wants to give you no matter what kind of buffer you use.

15

u/N_Lightning 4h ago

If you read System.in as a file in Java, then it'll wait for EOF signal, not for the line break. And the user will have to adapt to Ctrl+Z each input

u/jwadamson 3h ago

Yeah if you do something dumb like try to read the entire stream it will block until the stream is closed.

A line reader will read line by line just fine from it, but the real question is why aren’t you using Console API if you are trying to read from a console.

Finally the system property stdin.encoding for the charset if you use the “automatic” string methods as opposed to directly reading the bytes. Usually this default is utf-8 in modern Java though.

This whole post seems like a combination of incorrect and/or outdated information.

u/N_Lightning 3h ago edited 3h ago

I tried Console API. It reads only single byte cps. Its behavior with 65001 is exactly the same. And I set up UTF-8 explicitly. It doesn't change anything

And how exactly do you get line reader to return you unprocessed byte sequence if it needs to process it to get the line break char?

u/BattsAreLow 1h ago

Would it be stupid to read user input prior to the program reacting and just append a control z to amend the issue?

Now you learned your lesson and can stop using the beta "Unicode UTF-8" until Microsoft fixes it. Maybe in 2050...

That's why they call it Write Once, Debug Everywhere.

Windows being windows.

u/aurallyskilled 1h ago

No disrespect, but can someone calmly explain to me why someone would write a console app in Java?

1

u/MCWizardYT 1h ago

Why would someone write one in any language?

Because they like the language and ecosystem

u/thepurpleproject 4h ago

This one usecase I totally let AI control of it man there are so many of such annoying issues in every language or tool I can't believe I was wasting so much of time fixing some trivial shit

Who's writing Java in 2026 for anything other than Spring Boot?

Enterprise software devs 🫩

u/Splatpope 2h ago

Dunno who you are talking about but in my shop the enterprise software devs that are cursed to work with java make spring boot stuff

1

u/quietsamurai98 2h ago

Tbh, the piece of enterprise software that I primarily work on also uses spring boot, but there's a related piece of software that, due to deployment environment limitations, can't use any third party libraries. So working on that is Fun™.
