Installing OpenJDK 8 on Ubuntu 14.04

Tried to install OpenJDK 8 on Ubuntu 14.04 thought it would be as simple as doing a :

sudo apt-get install openjdk-8-jdk

but that didn't work out instead you need to do add the following repository:

sudo apt-add-repository ppa:webupd8team/java

Then execute

sudo apt-get update 

sudo apt-get install oracle-java8-installer

Optionally if you have multiple versions of the JDK then you choose which JDK should be the default one:

sudo update-alternatives --config java

Basically you choose the number and thats it.

You verify by doing :

java -version
