I am trying to install OpenJDK 8 in Freya but I can't find in any repository. If I try
sudo apt-get install openjdk-8-jdk
Unable to locate package
And when I try to search it via
sudo apt-cache search jdk | grep 8
I got no results. However version 7 is available in the repo. So do I need to add other repository in order to install Java 8?
