I'm trying to clear some stuff off my computer to make more room. I came across these two installed programs:

1. J2SE Runtime Environment 5.0 Update 10
2. J2SE Runtime Environment 5.0 Update 2

My question is would update 10 superseed or include any previous updates or does it stand alone as an update for whatever I needed the update for.

I guess my ultimate question is can I delete update 2 without any problems?

Kep the highest number and dump the rest.

Thank you that's the answer I was hoping for.

You need to be careful with Java as it may not be as straight forward which is used. So applications install their own standalone Java and chances are you need to update each individual installation of Java on your machine. Other applications hard code which installation of Java on your machine to use and do not necessarily follow the latest installed version.

Instead of deleting those directories I would suggest that you move them elsewhere on your system and then go through every application you installed on your machine that you think uses Java and run through it to make sure it works. If you come across an app that requires Java to be installed and tells you that you need Java installed then that's your culprit application. You need to have to do one of 3 things:
1. Repoint that application at the latest installed Java instance
2. Move back one of the Java installations one at a time until you find the correct one.
3. Reinstall your application

Good luck.
