Suppose you want to play Minecraft, in order to do that you need to have Java installed. You don’t have to worry about versions since Java is backwards compatible, meaning the latest version of Java is capable of running software that was built in an earlier version. In this “how to” we are going to install OpenJDK which is basically a free and open source variant of Java

Fire up Terminal and log in as root:

su

Then type:

yum install -y java-1.7.0-openjdk

Mind you if you need Java to be working in your browser too, you need to install the IcedTea plug in. You install this by typing the following command in Terminal (make sure that your are logged in as root!):

yum install -y icedtea-web

To check if Java installation was succesful, go this site. You will see this screen:

Press on the “Verify Java version” button.

A yellow pop-up screen will appear asking for your permission to run.

I choose to press on the “Run this time” button After you pressed on either button, some stuffies will go on on your screen, if Java is sucessfuly installed you will see this screen:

And you are done
