Process files in a directory

Sharp Tool - 29 Jun 2005 14:33 GMT

Hi

I have a large number (~1000) of files to analyse.
These files are in a directory.
I will use Java to run a program in batch mode to analyse each of these
files.
What is the best way of going through each of them.
I can think of providing the name for each of the files to the program to
analyse, but that doesn't sound very smart.
I would like to be able to go through each file automatically like if its in
a tree structure or something.
I hope what i said make sense.

help is appreciated
Sharp

Are you looking for java.io.File.list()?

Ciao,

Beyond the other comments, If you can use Java 5.0 take a look at
Coconut AIO package (Asychronous I/O) - its JSR is:

http://www.jcp.org/en/jsr/detail?id=203

Its available as a seperate package, almost made it into Java 5.0 and
has a good chance for 1.6/6.0 .
