There are many ways to install Java support in Linux systems. One of the easiest is to do it by adding specific entries to our sources.list file and install Java from repository. Open terminal and edit sources.list:
mcedit /etc/apt/sources.list
If you don't have mcedit then change editor's name to one that you use. Now add these repositories:
deb http://ppa.launchpad.net/webupd8team/java/ubuntu precise main deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu precise main
Now save modified file and run:
apt-get update
Final step is to install Java:
apt-get install oracle-java7-installer
