[SOLVED] update Java

[Chaoshay]

Hello to all
I need/want to update my java from 11 to 19 and seems I'm running into some difficulties.
Any dedicated LMDE tutorial on it?

Thanks in advance,
Shay

How did you install JDK 11?

I need/want to update my java from 11 to 19 and seems I'm running into some difficulties.

Technically, any 'updates' to your system will only apply to the openjdk-11-jre package, so it would still be Java 11.

At the moment though, Java 19 isn't available in the LMDE repos, so you won't be able to use the Package Manager to get this version. Only Java 17 is available as an alternative, possible because it is the latest LTS version.

I'm curious as to why you need Java 19. It's only been out for a month and therefore it would be surprising if any software was already making it a prerequisite. That said, if you need to download and install directly, rather than using the Package Manager, I would suggest looking at the OpenJDK website for further details.

If I needed JDK 19 then I'd download it from:
https://jdk.java.net/19/
un-tar it to
/usr/lib/jvm/java-1.19.0-openjdk-amd64
I symlink
to
default-java -> java-1.19.0-openjdk-amd64
And if you want it to be the version at the command line, you'll have to update alternatives.

Thank you very much!
