Install Oracle JDK

Now, the FZUG repository added oracle-jdk package, since no longer need to configure the environment variables.

$ sudo dnf install oracle-jdk7 oracle-jdk8

When you install the package, it will be download the JDK from Oracle's official website. The /etc/sysconfig/oracle-jdk is JDK environment variable configuration file. The ~/.bashrc contains a script used to loaded environment variable configuration.

Good job. :_)
