Sun Java on Ubuntu 11.10

Decided to 'fork' my previous post because since Ubuntu 11.10, Sun/Oracle Java has been removed from Canonical's partner repository. Fortunately, Roberto Ferramosca is providing the appropriate packages in his personal package archive (PPA).

So open your terminal, and let's go:

sudo add-apt-repository ppa:ferramroberto/java
sudo apt-get update
sudo apt-get install sun-java6-jdk sun-java6-jre sun-java6-plugin sun-java6-fonts

And that's it. Hope it's helpful. Now if you want to ensure Sun's JRE & JDK are the default, type in the terminal:
sudo update-alternatives --config java
and select your preferred alternative from the list. To select a Java compiler, type
sudo update-alternatives --config javac
Now on to the testing. You should get the version numbers of the currently installed and default runtime and compiler by typing (in the terminal):
java -version
javac -version
