Class in the java.io package

I found a class in the java.io package that I am not sure what it does. I think it's a FileFilter object...but i'm still looking into how it
works.

Any thoughts?

Filefilter is used to filter files from a given directory...its actually an interface and u have to implement that interface to return files with appropriate extensions...
for ex, if u need to get all html files from an given directory the implementation of accept method will look like this
public boolean accept(File file){
if(file.endsWith("html"))
return true;
else
return false;
}
