How to manage different java versions on Mac

Followed this guide (commands here not up to date)
- https://gist.github.com/tomysmile/a9a7aee85ff73454bd57e198ad90e614
Update home brew
- brew update
- brew upgrade
Install jenv with brew to manage java environments
- Add the below to ~/.bash_profile to initialize jenv

# Init jenv
if which jenv > /dev/null; then eval "$(jenv init -)"; fi

To set the version, run jenv local {java_version} (for that directory) or jenv global {java_version}
- jenv add /Library/Java/JavaVirtualMachines/{JAVA_FOLDER}/Contents/Home/
Use jenv versions to view available versions. You can view the Java paths in ~/.jenv/versions
The steps above handle setting the JAVA_HOME variable
Use cask to download java versions (not handled by jenv)
- brew required xcode command line tools: xcode-select --install
- brew tap adoptopenjdk/openjdk from devqa.io
- brew install --cask java
- brew install --cask adoptopenjdk11 (also adoptopenjdk8, adoptopenjdk13)
