Hello linux4noobs

I downloaded java 11.0.2 tar.gz (I know it is "old" but it's just for my learning purposes) from jdk.java.net/11 and installed it using the "tar" command. The problem is, how do I actually use this java installation?

In windows, I would just add the java /bin directory to the PATH, but I'm unsure how to go about this in Fedora.

I tried to use "update-alternatives --config java" to switch but the 11.0.2 version did not show up as an option. What steps do I need to take to make this the default version in my OS? If it matters, I'm getting into Java programming and that's the reason for installing it.

Hi all I just installed Fedora 40 and I'm a little confused as to why there are many different java versions installed on my machine, is it possible through some command to uninstall all the java versions, reinstall them myself, if so, would it break a lot? is there a better way of doing this?

The main issue is that vscode for some reason just isn't recognizing my current java-21-openjdk directory as my java runtime location so when i run a maven build of a spring boot project there are a lot of things going wrong...
