Want to install fresh jdk 6 for Android development. Before I had jdk 7 installed which I removed for fresh jdk 6 installation. Tried using the webupd repository way, not of use, tried downloading the jdk from oracle and then unzipping it, not of use.

I want to know if removing these listed packages will help?

java -version
The program 'java' can be found in the following packages:
* default-jre
* gcj-4.6-jre-headless
* openjdk-6-jre-headless
* gcj-4.5-jre-headless
* openjdk-7-jre-headless
 Try: sudo apt-get install <selected package>

EDIT: in response to MrVaykadji :

I tried doing the commands ... after i executed the sudo apt-get install ----- I encountered this error message at the end of log:

update-alternatives: error: no alternatives for java. 
update-alternatives: using /usr/lib/jvm/java-6-oracle/jre/bin/ControlPanel to provide /usr/bin/ControlPanel (ControlPanel) in auto mode.

    There is a nice guide on how to it ----- askubuntu.com/questions/67909/how-do-i-install-oracle-jdk-6 – Tasos Mar 25 '14 at 17:34
  • Those packages contain java but are not installed on your system, you will need to install one of those packages to install java; but those are openjdk java(s), not oracle, so may or may not be what you exactly want. – jobin Mar 25 '14 at 17:37
  • can u please suggest me how to install those packages...Thanks – user261972 Mar 25 '14 at 18:26
  • You must have broke something while uninstalling java7, I don't see any other explaination. – MrVaykadji Mar 25 '14 at 20:06

This sould be enough :

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java6-installer

If you encounter problems, edit your main post and leave a comment here ;)

Regarding your java -version output, the packages aren't installed yet, that's why Ubuntu tells you to install one of them.
