How to Install Java (OpenJDK) on Ubuntu

Before proceeding the installation, check first the existing Java installed in your system.

$ sudo java -version

 Once confirmed that there is an existing different version of Java installed, then execute the command below.

The command will show you the list all installed java packages.

Proceed with the installation of OpenJDK if they are yet in the list of the installed java packages.
 

$ sudo apt-get install openjdk-6-jdk

Verify if OpenJDK was successfully installed.

$ sudo apt-cache search openjdk
