The Guide shows you How to Install the Latest Oracle-Sun Java SE JDK 7 64-bit Release on Fedora Linux 16 x8664 GNOME3 Desktop.
Especially relevant: at the Same Time I’m also illustrating here How to Install the New Downloaded .rpm Packages with Dependencies on Fedora 16 GNOME Desktop :)
The Screenshots of Installation Correspond to the Install on a Fedora 16 GNOME3 Desktop but the Procedure on KDE, XFCE, Lxde is Similar…
Following the Easiest and Practicable Way I have Expressly Excluded the Use of Terminal Commands here.
So Take the Time of Carefully Reading and Executing the Instructions Contained Here and All should Work Like a Breeze :)

Installing Oracle-Sun Java JDK

If Got “User is Not in Sudoers file” then see: How to Enable sudo

YUM will Automatically Manage and Download the Eventual Dependencies Also for Local Packages :)
You Can Safely Ignore Eventual Installation Errors: “Could not open input file…”.
