Install Sun/Oracle Java JDK/JRE 6u45 on Fedora 19/18, CentOS/RHEL 6.4/5.9

Please note: This guide still working normally if you want install Sun/Oracle Java 6, but if you want Java 8 version, then check Install Oracle Java JDK/JRE 8 on Fedora, CentOS/RHEL or if you want Java 7 version, then check Howto Install Sun/Oracle Java JDK/JRE 7 on Fedora, CentOS/Red Hat (RHEL).

By default, Fedora 19/18/17/16/15/14/13/12 and CentOS/Red Hat (RHEL) 6.4/6.3/6.2/6.1/6/5.9 Linux operating systems use the OpenJDK Java, which is a good choice for normal use and it works with almost all the Java programs normally. OpenJDK is also easy to install and maintain with YUM package management, but some cases, Sun/Oracle Java installation is necessary, for example, if some program have to compile with Sun/Oracle Java or a particular program does not work without Sun/Oracle Java.
