sudo emerge --ask 	dev-java/oracle-jdk-bin
#accept license
sudo etc-update

[[32;01m*^[[0m Oracle requires you to download the needed files manually after
 ^[[32;01m*^[[0m accepting their license through a javascript capable web browser.
 ^[[32;01m*^[[0m
 ^[[32;01m*^[[0m Download the following files:
 ^[[32;01m*^[[0m   jdk-8u112-linux-x64.tar.gz
 ^[[32;01m*^[[0m at 'http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html'
