Execute the following commands:

sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
sudo apt-get update

Then, you can install sun java packages using the following command:

sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts

You can verify the availability of Java by executing the following command:

java -version

And : You can select version, if you installed more than one :

sudo apt-get update-alternatives --config java
... Then select "openjdk" or "sun-java6".
