Install Oracle Sun Java to CentOS

Install Oracle Sun Java to CentOS

Download Oracle Java 7 JDK for Linux:
http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
I prefer RPM. The tar.gz is an alternative available mainly for non-root users.

Note for x86 and x64
You can choose between x86 and x64 versions. You cannot install both together from RPM package. You can install one from RPM and the second manually from tar.gz.
