[HOW TO] remove Java environment on Ubuntu/ Linux

On computer I installed Java 6 update 45 as default java environment. But ... one day you have to uninstall . Do you know the method to do?

Below step could be done like this:

#update-alternatives --remove "java" "/usr/lib/jvm/jre-6u45/bin/java"
#update-alternatives --remove "javac" "/usr/lib/jvm/jre-6u45/bin/javac"
#update-alternatives --remove "javaws" "/usr/lib/jvm/jre-6u45/bin/javaws"
