I have been reading current posts and found this site to be an excellent resource! I am currently revving up to study for SCJP. Here's my question, originally I had installed jdk 1.2 a while back to play with and when 1.4 came out ... I didn't know if I could install 1.4 on top of 1.2 or just uninstall the old and install the new. Does anyone know?

Moving this to the Java in General (Beginner) forum.

As far as I know, you could install the newest and overlay the oldest, and it should work. But to be on the safe, I would uninstall the old and install the newest version.

I am not insane. The voices in my head told me so.

well I would advocate that too!!
Sometimes the classpath gets mucked when you have both the Versions. To prevent uninstall 1.2 and install 1.4!!
