Install Oracle Java Development Kit on Ubuntu

Installing Java SDK is very straight forward in Windows. Download Java installer double click it and follow the steps. But installing Java in Ubuntu is not easy like that. In Ubuntu we can easily install Open JDK by providing following command. 

sudo apt-get install openjdk-6-jdk

 But this installs Open JDK not Oracle JDK. This is not a problem for entry level Java developers. But if you work in a production environment you cannot use Open JDK since most products use Oracle Java. Until recently the method I followed to install Oracle Java was downloading the tar.gz file form Oracle site and install it using the terminal. But this is very time consuming and there are lot of configurations has to be followed. But here is a very easy way to install the latest Oracle JDK in you machine without not needing to do any additional configurations. Just issue following three commands in the terminal to install Oracle JDK in your Ubuntu machine.

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update 
sudo apt-get install oracle-java7-installer
