I need to create and execute small java programs.Can anyone help me install the jdk??

I didn't find a version for ubuntu

please help!

-C Arunkumar .

I think Java is in the "Multiverse" repository. In the /etc/apt/sources.list, find the line referring to the Universe repo, and add the word "multiverse" at the end.

Run "sudo aptitude update", and then you should be able to install the JDK using: "sudo aptitude install sun-java5-jdk".

If that doesn't work, I have instructions Here. Follow the Debian specific instructions, which should work on Ubuntu. Make sure you download the ".bin" from the Java website, not the rpm.

I hope this helps

But am not able to find jdk in my synaptic package manager nor I am able to run it.

what is the difference between apt-getand aptitude?


Thank you for you help!

-C Arunkumar

Try: "apt-cache search sun-java5-jdk" and see what shows up. Have you added the "multiverse" repository and run apt-get update?

As for apt-get v aptitude, try [URL="http://www.psychocats.net/ubuntu/aptitude"]This[URL] page for an excellent description.

sorry I hadn't added the multiverse in the right place.I was able to install it using the same command after adding it.Thanks a lot for the help and the link!

Additional hints (for the command line) (check them at any rate!):

My $HOME/.bashrc file (which gets interpreted everytime I logon) looks like that:

Thanks for you helpnewbie: .But I didn't understand the commands you posted.
What is it used for?


-Arunkumar C

1) "which java" - gives the path the the command java. In some cases, you may have several executables called "java" and this command tells you which one you are executing.

2) See "man update-alternatives" for a good description.

3) The next commands simply print (echo) the value of the environment variables "$JAVA_HOME" and "$CLASSPATH". They should be set correctly if you installed using the package.

4) The export commands let you set these environment variables if necessary, though I wouldn't bother with this at the moment.

5) Your ~/.bashrc is a config file that is read everytime you start a new shell (that is not a login shell). Those lines will set those environment variables to the correct values when you start a shell. Don't worry about this though, they should be set correctly by the package installer.

I hope this helps

PS: Google would have given you good answers to all of these...

Thanks a lot!

I don't know if Easy Ubuntu (I think that's the name) has it but I know Automatix2 does. Even has a GUI now.

Java5 installs easily with the Synaptic Package Manager. No command line required. There are also a number of development environments. Eclipse is a popular one.

Thank you!
