I'm new to ubuntu (but i like it a lot), so please bear with me.

I want to install Java, but which one should I install?

  • The RPM or the normal one?
  • 32bit or 64bit?

From what I know, even windows 64 bit is still using java 32 bit. This thing make me confused.

I'm asking here just to make sure everything is going to be all right, because I will need my system to be ready to code (eclipse :D) pretty soon, so I want to avoid any trouble now.

Thanks for your help, and sorry for my basic question.

  • I don't think there is a reason not to use 64-bit Java on 64-bit OS, be it Linux or Windows. – MadMike Oct 07 '13 at 13:53
  • @MadMike because im new to ubuntu, i prefer to avoid using terminal for now. Thanks for your help :D – Blaze Tama Oct 07 '13 at 13:55
  • However, im still confuse, which one should i download? The RPM or the other one? – Blaze Tama Oct 07 '13 at 13:55
  • Use the DEB-files whenever possible – MadMike Oct 07 '13 at 14:27
  • Follow the advice of the accepted answer in that question. You don't need to use the terminal. Java is installable from the Software Center. – dobey Oct 07 '13 at 15:08

    If you need to install the latest eclipse, usw this [article] ( http://askubuntu.com/questions/26632/how-to-install-eclipse) – MadMike Oct 07 '13 at 15:46
  • Since you're using Ubuntu there's no reason to install RPM since RPM is a package manager specific to Redhat/Fedora distros. Ubuntu uses the Debian package system. Since you're on a 64 bit system you should be installing 64 bit software. The only reason to install 32 bit software is if an application you're installing isn't available for 64 bit and in that case your package manager doing the install will handle the 32 bit installs for you. So as a general rule always install the highest bit that your system is compatible with, in your case 64 bit. The only reason to use RPM on a Ubuntu system – A H Oct 07 '13 at 14:32

If you are using Ubuntu, you don't need to worry about this. Open the software center and search for eclipse. The installation of eclipse will also take care of the Java jdk.

  • And one more question, will it automatically choose what version i download? (like indigo, juno etc) – Blaze Tama Oct 07 '13 at 13:58
  • the version of eclipse will be the latest one in the Ubuntu repository. So, you will not given a chance to select the version. in 13.04 it is Indigo, afaik – Anwar Oct 07 '13 at 14:07
  • @madmike when someone says he need eclipse to code java, you don't need much intelligence to infer that he needs jdk. fyi, without jdk you can't develop java code – Anwar Oct 07 '13 at 15:26

Just open a terminal and type

sudo apt-get install default-jre

Enter your pasdword and wait. Now you have the normal JRE on your computer.
