The language itself derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. JavaScript, a scripting language, shares a similar name and has similar syntax, but is not directly related to Java.
Currently 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
Installing the Java Runtime Environment
First you need to check multiverse repository enabled or not after that open a terminal window. Since you are going to be installing the JRE and the web browser plug-in, you'll be using the following command from a terminal
sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts
Once it downloads the packages and begins the installation, you'll get a screen that contains the Sun Operating System Distributor License for Java and hit Enter to continue. You'll see a dialog that asks you if you agree with the DLJ license terms. Select Yes, and hit Enter; the JRE will finish installing.
Testing Java Runtime Environment
You'll want to confirm that your system is configured properly for Sun's JRE. This is a two-step process.
First, check that the JRE is properly installed by running the following command from a terminal.
java -version
You should get similar output
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)
Testing Java Plugin for Firefox
open Firefox and typing about:plugins in the address bar and check for java plugin
Try this – go to http://www.java.com , click “Do I have Java?”, Firefox will say you are missing a plugin, let it install Java. Done!

Wow, that’s a thought-provoker How to Install Java Runtime Environment (JRE) in Ubuntu | Ubuntu Geek! Tiffany Argenti
Hi, I found this post while searching for help with JavaScript. I’ve recently switched browsers from Google Chrome to IE. Just recently I seem to have a issue with loading JavaScript. Everytime I go on a site that requires Javascript, my computer freezes and I get a “runtime error javascript.JSException: Unknown name”. I cannot seem to find out how to fix the problem. Any aid is greatly appreciated! Thanks

root@ubuntu:/# sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts

Package sun-java6-jre is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package sun-java6-jre has no installation candidate
How can I update from Ubuntu 9.10 Karmic Koala (which am currently using) to Ubuntu 10.04 Lucid Lynx off-line just using the CD image and retain my documents?
If you install it on the old partition, deleting the old OS (9.10), all your old files will be deleted, unfortunately.
Same as Tom Todhunter:
E: Package sun-java6-jre has no installation candidate
I’m so tiried of pogo not letting me play my games .I don’t know if its pogo or java .But I pay for pogo please help me.Its just not fair.
If you are running ubuntu 10.04 try this http://www.ubuntugeek.com/how-install-sun-java-runtime-environment-jre-in-ubuntu-10-04-lucid-lynx.html
sudo add-apt-repository “deb http://archive.canonical.com/ lucid partner”
Will enable the partner repo and allow you to install the jdk via
apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts
I’m having exactly the same problem as Tom Todhunter
Please advise
If I do: sudo add-apt-repository “deb http://archive.canonical.com/ lucid partner”
I get: Error: need a repository as argument
Have I missed something?
Don’t forget the apt-get update after adding the new repository.
Here’s a FAR SIMPLER solution if you are running a GUI version of Ubuntu:
(1) go to System / Administration / Synaptic Package Manager
(2) Inside the Package Manager choose Settings / Repositories
(3) Click the tab for “Other Software”
(4) Select “ubuntu lucid partner” – this will likely be the first option
(5) Close the Settings windows then click “Reload” in the main Package Manager window.
(6) Type “jre” into the search field and press enter
(7) Select the jre in the list of results, be sure to choose “Mark for Installation”
(8) Click the “Apply” button.
This worked for me. It’s more steps than using the command line, but it’s much simpler.
Matt’s answer worked for me. Thank’s Matt.

You might want to run `apt-get -f install’ to correct these:
The following packages have unmet dependencies:
sun-java6-jre: Depends: sun-java6-bin (>= 6.20dlj-1ubuntu3) but it is not going to be installed or
ia32-sun-java6-bin (>= 6.20dlj-1ubuntu3) but it is not installable
Recommends: gsfonts-x11 but it is not going to be installed
sun-java6-plugin: Depends: sun-java6-bin (>= 6.20dlj-1ubuntu3) but it is not going to be installed
E: Unmet dependencies. Try ‘apt-get -f install’ with no packages (or specify a solution).
