DaniWeb Member Rules (which you agreed to when you signed up) include:
"Do provide evidence of having done some work yourself if posting questions from school or work assignments"

Post what you have done so far and someone will help you from there.
ps: This is not a hard assignment

Its not an assignment or school work
the thing is only ask is it possible or not

OK, in that case: Yes, it's possible, it's actually quite easy.

If you have Java 7, use the NIO ("new I/O") classes; here's the excellent Oracle tutorial that tells you all you need to know:

If you are stuck on an earlier release for some reason you can still do the same thing using Java's original File class, but you'll have to download the old version of the tutorials from http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-tutorials-419421.html#tutorial-2008_03_14-oth-JPR
