How to install Java 7 on Ubuntu 12.04 LTS

Oracle JDK is no longer included by default in Ubuntu’s repositories due to           licensing. OpenJDK is default now but many apps still don’t play nice with it. This   is why I installed Oracle JDK.

I’ll walk you through the process of installing Oracle JDK 7 on Ubuntu 12.04 LTS      Precise Pangolin, the easy way. For this we will use the “install oracle-java7-       installer” package from “WEBUPD8″.

The “install oracle-java7-installer” package from “WEBUPD8″ will download the         official binaries from Oracle and install the JAVA 7 JDK, JRE and browser plugins on  your machine.

1. Add the “WEBUPD8″ PPA.

danesh@python:~$sudo add-apt-repository ppa:webupd8team/java

2. Update your repositories.

danesh@python:~$sudo apt-get update

3. Install JAVA 7 JDK.

danesh@python:~$sudo apt-get install oracle-java7-installer

To uninstall,

sudo apt-get remove oracle-java7-installer
