Installing sun-jdk 1.7 on Linux Mint

Finding how to install it was very confusing as there was no sun-jdk in the package manager. Here are the manual instructions:

1. Download jdk-7u6-linux-x64.tar.gz from the Oracle-Sun java web site.
2. Extract it
3. It's ~/Downloads/jdk.1.7.0_06 now.
4. sudo mv ~/Downloads/jdk.1.7.0_06 /usr/lib/jdk.1.7.0_06
5. sudo ln -s -v /usr/lib/jdk.1.7.0_06/bin/java /usr/bin/java
6. sudo ln -s -v /usr/lib/jdk.1.7.0_06/bin/javac /usr/bin/javac

That's it!
Hopefully.
