Hello everyone!
I need to write a java application that it can alert when one
directory is changed.

For example, If one file of the directory is added, modified or
deleted, the application alert about this change.

Previously I have to determine what is the root directory.

Thanks in advance!

Mariano

Thanks for letting us know what you will be doing. I'm not sure how
much use this knowledge is to the group, though.

Sorry I forgot to ask the following question, Does exist any
implementation that detect when a directory is modified or similar?

Unless your OS presents you with a special API for this purpose, all
such implementations I've seen are based on polling; i.e. repeatedly
scanning the directory and/or files of interest to check if they've
changed since the last scan.

Not that I've ever heard of, unless as Oliver says someone has done a
library to assist in this task. You might roll your own.
Did you trying searching the web for keywords like "java directory
monitoring"?
lex

p.s. the java.io.File class might be useful if you're looking at writing
your own.

I have written my own small utility to do this task.
