cd ~
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/7u79-b15/jdk-7u79-linux-x64.rpm"
# Then install the RPM with this yum command (if you downloaded a different release, substitute the filename here):
sudo yum localinstall jdk-7u79-linux-x64.rpm

# Now Java should be installed at /usr/java/jdk1.7.0_79/jre/bin/java, and linked from /usr/bin/java.
