Download and Install OpenJDK 14

Download the .tar.gz version of OpenJDK 14 from

sudo mv openjdk-14.0.1_osx-x64_bin.tar.gz /Library/Java/JavaVirtualMachines/
cd /Library/Java/JavaVirtualMachines/
sudo tar -xzf openjdk-14.0.1_osx-x64_bin.tar.gz
sudo rm openjdk-14.0.1_osx-x64_bin.tar.gz

Next, execute the following command to find out where JDK 14 is located:

$ /usr/libexec/java_home -v14

and append the resulting path as an export into your .bash_profile:

echo -n "\nexport JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-14.0.1.jdk/Contents/Home" >> ~/.bash_profile

and make sure to apply the changes:

source ~/.bash_profile

Test Java
