Which one can I uninstall?

I have:

J2SE Development Kit 5.0

J2SE Runtime Environment 5.0 Update 2

J2SE Runtime Environment 5.0 Update 4

Java 2 Runtime Environment Standard Edition v. 1.3.1_04

I know that I can uninstall one of them, but I need advise on which one.

I use these programs only to run Limewire.
