Installing Java in Ubuntu Linux

One of the reasons I love Ubuntu (Linux) is because it comes with a great number of packages.

Ubuntu has the following Java packages

sun-java6-bin – Contains the binaries
sun-java6-demo – Contains demos and examples
sun-java6-doc – Contains the documentation
sun-java6-fonts – Contains the Lucida TrueType fonts from the JRE
sun-java6-jdk – Contains the metapackage for the JDK
sun-java6-jre – Contains the metapackage for the JRE
sun-java6-plugin – Contains the plug-in for Mozilla-based browsers
sun-java6-source – Contains source files for the JDK

Here is a quick and dirty way to install Java in your Ubuntu desktop / server

Edit the sources list

$ sudo nano /etc/apt/sources.list

Insert the following lines at the end of the file

deb http://us.archive.ubuntu.com/ubuntu dapper main restricted
deb http://us.archive.ubuntu.com/ubuntu dapper universe multiverse

Save (Ctrl+O ) and Exit (Ctrl+X) the file.

Update apt

$ sudo apt-get update

Now in terminal run the command line

$ sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts

Agree to the terms and java will install automatically.


Test that Java install is successful
Run command

$ java -version

You will get something like

java version “1.6.0″

Java(TM) SE Runtime Environment (build 1.6.0-b105)

Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing)
