It's one place you can set a shell's environment. IIRC that file is
only used for "login" shells.

jdk1.1
(use 'dpkg -S /usr/bin/java' or "dlocate", or dereference the symlinks
to find where the actual executable is and query on that file instead)

It won't unless you have another package installed that provides java.
Once you install the j2re1.3 or j2re1.4 package there will be more
than one provider of "java" for update-alternatives to switch between.

That would work as well.
On my system I have a number of scripts in ~/bin (which is first on my
path) named like java-1.2, java-1.3, java-1.4, javac-1.2, javac-1.3,
javac-1.4. The scripts are really short just to set environment as
necessary (j2sdk 1.2 needs $JAVA_HOME set) and exec the java program
via the absolute path. The purpose is to allow me to easily use
whichever java I want at the time. Since I end up doing java
development I need to run different versions for testing.
HTH,
