i have Java DB 10.3.1.4, Java™ 6 Update 4, and Java™ SE Development Kit 6 Update 4 installed on my computer. are they all the same thing or three different things?

If you are just a user and not a developer ..all you need is..

Java Runtime Environment (JRE) 6 Update 4

Java Runtime Environment (JRE) 6 Update 4
The Java SE Runtime Environment (JRE) allows end-users to run Java applications.

note: that is the 4th one down at this link and not the others.

If you want to know why you can see here...

So if you have installed others you mentioned ..you can go to add/remove programs and uninstall them...also you should uninstall ALL the older version of Java Runtime Environment (JRE).


BTW Java Runtime Environment (JRE) 6 Update 4 will show up in your add/remove programs as Java™ 6 Update 4
