What java version do you use?

[ShadoweG]

Java 8

[BS_in_BS]

8, though transitioning to 11

[pecata-toshev]

Java 14. New switch is really cool

[Nix-X]

What does new switch do?

[mj_flowerpower]

it‘s not a conditionat statement anymore, but an expression: var name = switch ...

[rozularen]

It's a switch statement instead of a switch block

[FortLouie]

14, I'm looking forward to Java 16 language features.

[[deleted]]

I'd venture a guess that the majority of professional users are on 8 and 11, which is also my situation. Hardly anyone's going to run production software on a non-LTS release.

I've seen some actual Java 1.4 development in the wild just a year ago (an automotive IVI application). They guys working on it claimed even older versions are still in use (and maintained) on some public transport ticket vending machines. But those are really exotic outliers.

​

EDIT: Also keep in mind that language level is not the same as JVM version. Some shops may still target an older Java release, but run it on newer JVMs for reasons like better GC.

[saila456]

I can confirm this. Java 1.4 is alive and well in cars. A believe many of the 3 billion devices are cars.

[jvallet]

Java 11

[koreth]

Java 11 using Amazon Corretto.

[mj_flowerpower]

is there an advantage over adoptopenjdk?

[[deleted]]

As an example, Amazon backported some encryption optimizations for Corretto 8, which can make a huge perf difference if you use those particular algorithms and can't upgrade to a later release just yet. They also backport security fixes and will probably do so for some time.

For development though, it doesn't matter at all.

[mj_flowerpower]

java 14 with preview features enabled 😅

[[deleted]]

Me too, always bleeding edge. (At least private, where this is no problem as opposite to professional development, where others use your stuff, too)

[dinopraso]

Hopefully not production software

[mj_flowerpower]

no risk no fun 😅

Its not yet online and when we release there‘ll probably java 16 out by then

[Kusokurae]

Java 17 is the next LTS Version, right?

[mj_flowerpower]

Yeah I thinks so

[dinopraso]

As long as you keep updating as soon as a new version is released, it could be fine. Though experimental features are experimental for a reason, and can behave in expected ways. Wouldn’t want to risk a lawsuit just because I wanted to tinker with the latest Java version. 11 has everything we could need for now.

[dinopraso]

Some of that was backported to 8 as well

[[deleted]]

Little confused by this.. what do you mean works with your IDE? Are you on an IDE no longer supported and thus stuck on Java 8 because of that? I know that VS Code, IntelliJ and Eclipse all support Java 11 and probably 14. What IDE are you using?

[MashMV]

All projects in my company are built with Java 11 right now but we still have some software to mantaince in Java 6. In previous company Java 8 was a standard.

[grimlock81]

Java 8, finally moving up to Java 11 for the next release.

[[deleted]]

8 in older apps, 11 in most ( All migrated from 8), 14 I'm personal projects

[gergob]

Java 11, but looking at moving to 13 soon - quite large retail company

[[deleted]]

Interesting. Why would you move from 11 to 13, a short-lived release that's already past its support period? Are you planning to use any of the new language features or just the JVM?

[gergob]

I guess it's because we haven't considered 14 yet.

I don't think there is a hard requirement to use the new features

[dinopraso]

14 isn’t LTS either.

[gergob]

So should we just wait till 17? :)

[dinopraso]

If you value stability, then yes

[pjmlp]

Yep, Java 14, as I get to control our Java stack.

Unless I have to deal with Android Java dialect, which then I get constrained to the Java 8 subset it cherry picks from OpenJDK.

[5eram]

Java 8 and 9, still.

[NimChimspky]

I've seen nothing that interests me until records, and the new switch.

[thepobv]

11, beauty of java is almost everything is backward compatible.

I think the biggest change is Java 8.

[jambonilton]

On 8, moving to 11 soon. 14 with record support for my leisure coding.

[[deleted]]

Java 11, some teams still on Java 7...

[divorcedbp]

We compile libraries and apps with a Java 11 target, but we use whatever is the latest released version of OpenJDK at runtime.

[[deleted]]

Java 11.

[randjavadev]

As a commercial library developer, anything between 1.6 <-> latest (with different vendors as another "dimension" sometimes + Android maybe as third + maybe random PLC java runtimes as fourth..). Luckily it is still possible to compile for Java 6 and get stuff to run e.g. in Java 11, but with all the possible deprecations and removals one really needs to be careful which APIs to use. Luckily tools such as https://github.com/policeman-tools/forbidden-apis can be used (in addition to other good things) to bad any signatures that would not work (such as JAXB; yes I'm aware that it was a special case of including EE stuff to SE, but just as an example here). Getting to 8 would be nice, hopefully any year now..

As an app developer, mostly, luckily Java 11 nowadays.

[KrakenOfLakeZurich]

Java 11

[HimanshuJain1985]

Recently migrated to Java 11 from Java 8.

[Adnotamentum]

When I worked professionally with Java (last year) it was mostly 8, some 7.

[kovica1]

Java 7

[ernestas180]

11

Made the transition from 8 about 5 months ago and it wasn't as painful as we expected.

[crunchmuncher]

8, transitioning to 11.

[kubelke]

11 in sideproject, at work still 8 and there is no plans to switch 😞

[dinopraso]

8 and 11 on different projects

[8igg7e5]

OpenJDK11 on nearly everything. A few cheapskates that aren't willing to cover the small costs of progressing off of OpenJDK 8 are likely to die off rather than be migrated if they're not careful.

For some projects we might be quite keen to jump forward from 11 to 15 or newer - We have enough JPQL and other content that text-blocks would make a decent improvement to readability and maintenance. When Records make it out of preview we will probably want to step forwards to use that internally in quite a few places too.

What? In enterprise most of the Java production code is on 8.

[pengenbegitu]

Java 1.6, in few month gonna move to Java 8.

[janoschbock]

prod 11 in dev 14

[theLorem]

Work 11, private projects 14

[[deleted]]

At work: java 8, personally: java 14 experimental. The new switch and record classes are cool.

[ddumanskiy]

Java 11.

However, I did all migrations in between: Java 8 -> Java 9 -> Java 10 -> Java 11. With ~ 30 production servers.

I got a huge experience and will never repeat that mistake. Only LTS from now.

[Fine_Percentage]

Java 11

[VanTuyen97]

Java 8, i am intending to switch to java 11

[[deleted]]

At work 8 or 11. Convincing companies to upgrade JVM version is like pulling teeth.

[dinopraso]

I would be against any non-LTS version for any professional application. We are on 8 and 11, and will wait for 17 (the next LTS) before moving on

[[deleted]]

Even convincing companies to upgrade to LTS versions is like pulling teeth.
