You can find out where is java installed by running "which java". The version can be determined by running "java -version". To install Sun's JDK 6, switch to root and run "apt-get install sun-java6-jdk". You can also run sudo if you don't want to switch to root: "sudo apt-get install sun-java6-jdk". Proceed with the installation and confirm the license terms. Now you should get the correct message when running "java -version": 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) http://stackoverflow.com/questions/9918093/installing-sun-java6-jdk-on-ubuntu-10-04-64-bit-os ``` you could install sun jdk for Ubuntu 10.04 in the same way as 10.10. The steps for installing java in 10.10 is described in http://java.dzone.com/articles/sun-java-6-ubuntu-1004-1010 here's the steps of installing sun jdk, taken from that article:
add-apt-repository ppa:sun-java-community-team/sun-java6 apt-get update apt-get install sun-java6-jdk update-java-alternatives -s java-6-sun
