Hello. I am now using Java to write a File manager.

I use listRoots( ) to list out all the roots of the system and then use
for-loop to create label for each root. Also each label is related to a
root name, i.e. A:/, C:/, etc.   Afterwards, i add the mouseListener to
the label inside the for-loop.  But i have a problem that i can't
display the roots name when i click on a label.  e.g. label[i] is
related to rootsName[i], i want to display rootsName[i](which is a
string) when i click on label[i].  The complier said that i use
non-final variable.
Could anyone tell me how can i do?
I am glad to hearing to any advices.

regards,
Priscilla
