Here’s the installation instructions for OpenJDK 8.
For Fedora, Redhat and Oracle Linux.
yum install java-1.8.0-openjdk |
For Debian and Ubuntu.
apt-get install openjdk-8-jre |
To see if the packages (symbolic links) are there, they can be found in /etc/alternatives/, at least in Redhat 7.
ls -l /etc/alternatives/ |
