which is correct.
Where is $JAVA_HOME set or how do I add it to the path permanently?
You have to set it yourself.
Options include /etc/bashrc, /etc/profile, /etc/profile.d,
/etc/environment, /etc/environment.d, and possibly others, for setting
it system-wide, and their per-user counterparts in $HOME for setting it
on a per-user basis.

Thank you for your prompt response.
Adding Java to the $PATH variable requires me to know the location
where Java was installed, which I don't know. Is there a way to find
out where Java was installed?
Maybe this could help :
$ java -version
openjdk version "11.0.16" 2022-07-19
OpenJDK Runtime Environment (build 11.0.16+8-post-Debian-1)
OpenJDK 64-Bit Server VM (build 11.0.16+8-post-Debian-1, mixed mode,
sharing)
$ update-alternatives --config java
Il existe 6 choix pour l'alternative java (qui fournit /usr/bin/java).
