jenv VS SDKMan

https://github.com/jenv/jenv to switch among multiple Java versions

I would recommend https://www.jenv.be/

Look at the https://www.jenv.be/ configure section and add the Java location where Homebrew installed your java. If I remember correctly, it should be somewhere in /usr/local/Cellar/openjdk/**

On my case I prefer use jenv (which is available on aur)

You might like jenv

There are a handful of different ways to temporarily swap out Java versions. In this case, you could probably edit the start scripts to point directly to the path for the Java version you want to use (instead of just "java" which is most likely referring to the most recent). I was already using jEnv for other things, so I configured it so JRE 1.6 would be used in my Nullpomino directory, and the latest JRE would be used everywhere else.

I like jenv for that. You can have a java version set per-project, systemwide, shell session, etc.

I don’t know if this is the “correct” way, but if you are Unix based I would recommend jenv. This is a Java environment manager, similar to pyenv if you know it. Using this tool you can easily switch from one installed version to another. It makes managing Java versions a bliss.

Alternatively, you can use sdkman. A great tool to install your Software Development Kit. The downside is that it only works on *nix systems. So for Widnows users, you will have to use WSL or Cygwin as the official page suggests. It is really simple to use sdkman. after a successful installation, just type those commands into your *nix shell:

To run the example, you must install the Auth0 CLI and create an Auth0 account. If you don't have an Auth0 account, sign up for free. I recommend using SDKMAN! to install Java 17+ and HTTPie for making HTTP requests.

Another option for installing Java is SDKMAN!, a versatile tool that’s easy to install and helps you manage multiple versions of Java.

Java 17

Java 17 or higher. You can use SDKMAN! to install Java if you don't have it already.

Ktor, a powerful web framework built with Kotlin, offers a lightweight and flexible solution for building web applications. In this article, we will guide you through the process of creating a Ktor project manually using Gradle and SDKMAN!. By following the steps below, you'll have a basic Ktor project up and running in no time.

If you have any tips/advice then I'm all ears. I've already modified the dnf.conf with fastmirror and max_parallel_downloads I'm currently not using sdkman because this is my personal machine, so I don't mind always using the latest version OpenJDK. If I ever do need to switch between versions then I'll switch over to sdkman instead.

For handling your JDK: I highly recommend purging your system of all JDKs/JRMs - get rid of it all - and download SDK (if you're using Windows, you'll need to do this through WSL). This tool manages software development kits very well; switching between JDKs is super straightforward: sdk use .

I use sdkman to install java related stuff. Check it out. No root needed.
