How do I switch between Java versions?
There is a useful tool on Linux/Mac called jenv that allows you to set the jvm to use for a directory and its subdirectories. Someone has created a port of that to windows here: https://github.com/FelixSelter/JEnv-for-Windows

Error when creating a Forge/Fabric Better Minecraft server 1.19.2
You can use Jenv to manage your different java versions. I would recommend using JDK 11 instead of 8 (since JDK 8 has already ended active support, and therefore should not used in production enviroments) for anything 1.12.2 or lower. Then remove 16 and 18 since those probably won't be supported soon (JDK 18 is ending both active support and security support in 2 months). So you are basically left with JDK 8, 11, and 17. Then set your global java version with jenv to be 17, and for any servers that need 11, just set the local directory to use 11 instead

I keep getting this error when running the .bat file when trying to start up a new server what's causing this and how do I fix it?
This error comes up so many times on this sub. The solution is to update to a later java version. You are running Java 8 (Java Bytecode Version 52.0), while what you really need is Java 17 or higher (Java Bytecide Versoin 61.0+). Uninstall Java 8, and then replace it with Java 17. The recommended runtime is Eclipse Temurin or Amazon Corretto. Install either of them (make sure that it is Java 17), and run java --version to double check. If you need to run both Java 8 and 17 on the same system (eg you run a modded 1.12.2 server along with a Paper 1.19 server), then you'll probably want to install JEnv.

need help
generally, u might need to use a java version manager. This should hopefully allow you to keep your current jdk version, but also switching to another one for the server. a good one is JEnv, which works by switching java versions as needed. For MacOS and Linux, use this one (https://github.com/jenv/jenv), while for Windows, use this one (https://github.com/FelixSelter/JEnv-for-Windows). It's very similar to something like rbenv or nvm, but you have to install the java versions yourself.

Install Asdf: One Runtime Manager to Rule All Dev Environments
I would suggest learning how to use SDKMAN: https://sdkman.io/
It will manage the JDK for you. Usage is basically this:
# Install a JDK, that version is now default

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.

First time Linux user
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.

MOOC.fi question - Is there a way to automatically default to JDK 17 to where I don't have to set up an SDK every single time?
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 .
