    [macOS] Install OpenJDK

Instructions on how to install OpenJDK on macOS.
Uninstall

First step should be to unsinstall any previous OpenJDK installation. This
step can be skipped if no OpenJDK version was previously installed.
To uninstall any previous OpenJDK installations use the following commands:
sudo rm -rf /Library/Java/JavaVirtualMachines/jdk-*.jdk
Install

OpenJDK can be obtained here (or here
for older versions). Copy the link for the version that you want to install from there.
Get the OpenJDK archive and extract it with the following command:
curl --silent --location --retry 3 "https://download.java.net/java/GA/jdk17.0.2/dfd4a8d0985749f896bed50d7138ee7f/8/GPL/openjdk-17.0.2_macos-x64_bin.tar.gz" | sudo tar xz --no-same-owner -C /Library/Java/JavaVirtualMachines/
Configure

Add the following line to the .bash_profile file:
export JAVA_HOME=$(/usr/libexec/java_home 2>/dev/null)

Verify

Open a new terminal window and check if java is installed:
java -version
javac -version
Also check if the JAVA_HOME environment variable was defined using the following command:
echo $JAVA_HOME
