I am on Debian Squeeze. My java is 1.5.0 & javac is 1.6.0_24, does it mean that my Java installation is inconsistent? what is the latest package I should be having?

Checkout alternatives
It seems your different java programs are pointing to different executables. Debian uses a redirect with links for program for which alternative implementations exists, like java with the gcj, kaffe, sun-java5 and sun-java6, openjdk, …
In the past you had to swap them all individually with the update-alternatives program.
I recollect there was something to do it all at once now : update-java-alternatives. It is aprt of the java-commons package. see also this post
shows you which java versions are installed
would set all java related programs to point to the openjdk version.
Typically there is a gui tool to help you do this. On my Ubuntu (also debian based) system it System –> Administration –> Alternatives Configurator.
