This simple tutorial is going to show you how to easily install Oracle Java (JDK) 6, 7, or 8 in Ubuntu 14.04 Trusty Tahr via PPA.

There’s a Launchpad PPA (Personal Package Archive) maintained by webupd8.org, a popular Ubuntu Linux blog, which provides the most recent installers to automatically download and install Oracle Java JDK6 / JDK7 / JDK8 from oracle website. Note there are no actual Java files in this PPA.

To install Oracle Java 8, run:

sudo apt-get install oracle-java8-installer

Change the number 8 to 6 (or 7) in the code to install Java 6 (or 7).

While installation, you’ll be asked to agree the license and then the installer start downloading Java file from oracle website and install it on your system.

To set the default Java, run:
