-### SDKMAN

-*SdkMan* is not necessary, but helpful to install and switch between different versions of SDKs (Software-Development-Kits) and development tools in general, e.g. *JDK* and *Gradle*.
-It is available for _Linux_ and _MacOS_, _WSL_, _Cygwin_, _Solaris_ and _FreeBSD_.

-You can get it from: https://sdkman.io/.

-Yeah, the `curl ... | bash` install method looks quite scary;
-but in a development environment you're downloading executables all the time,
-e.g. through `npm`, `Maven` or `Gradle` when downloading dependencies.
-Thus, maybe you should at least use a separate Linux account for development.
-
-Once it's installed, you can install *JDK* and *Gradle*:
-
-    sdk install java 17.0.3-tem
-    sdk install gradle
-
-    sdk use java 17.0.3-tem # use this to switch between installed JDK versions
