Me again asking more questions 
sorry if i'm annoying you but my only purpose is learning !!
So i have this window
In the JList on the have i'll list the subjects .(i have no problems with this part)
now depending on the subject i click from the first JLists,it's existing questions will appear in the right JList(no problems here as well)
my problem is when i try to add an item listener for the second JList.
do i need an observer in here ?

Everyone should learn how to code, it teaches you how to think.
You don't have to be a Genius to know how to code you just need to be determined.
The computer is incredibly fast, accurate, and stupid; man is unbelievably slow, inaccurate, and brilliant; together they are powerful beyond imagination.
