General Conduct

Upvote good content, downvote spam, don't pollute the discussion with things that should be settled in the vote count.

Do not post tutorials here! These should go in /r/learnjava.
No programming help questions here! These should be posted in /r/javahelp
No surveys, no job offers! Such content will be removed without warning.

r/java Rules

1

No Programming help

r/Java is for News, Technical discussions, research papers and assorted things of interest related to the Java programming language, not for help with Java programming. Such "help with programming" posts should go to r/javahelp.

2

No Trolling

We all like some good discussions, but a few topics have gotten stale. Please refrain from complaining about certain Java features (or lack thereof) or extoling other, possibly superior languages. We get it – yours is bigger than ours (language, that is).

3

No Jokes / Memes

Not that I don't have humor, or that I can't have a good laugh, but most of the "jokes" that had been posted here were extremely stale and absolutely unfunny.

4

No Tutorials

Tutorials should not be posted here, they should go in r/learnjava instead.

5

No Surveys

We do not allow surveys.

6

No Job offers

r/Java is not a job market. We do not allow job offers.

7

No Piracy

We do not allow asking for or offering pirated material.

8

No Political Discussions

r/Java is a technical subreddit.

Leave political discussions out of technical discussions. If you want to discuss politics, go somewhere else.

Political comments will be removed and the poster will be banned.

9

No AI

This is an AI free zone. 100% AI free. We explicitly forbid any form of AI generated/worked over content, or AI supported or vibe coded programs. Any violation results in an instant, permanent, and irrevocable ban without prior warning.

Where should I download Java?

With the introduction of the new release cadence, many have asked where they should download Java, and if it is still free. To be clear, YES — Java is still free.

If you would like to download Java for free, you can get OpenJDK builds from the following vendors, among others:

Adoptium (formerly AdoptOpenJDK)
RedHat
Azul
Amazon
SAP
Liberica JDK
Dragonwell JDK
GraalVM (High performance JIT)
Oracle
Microsoft

Some vendors will be supporting releases for longer than six months. If you have any questions, please do not hesitate to ask them!
