how to find files in given directory

[cecily]

in my program I have to get directory name&address, in this directory is none, one, or more *.txt(maybe not *.txt files) and I have to read info from all of them.

on C++ is very easy to do that with "findnext, find last, findfirst", so how can I do this in Java?

You can use java.io.File class and its list() or listFiles() method with FilenameFilter argument. Both return a array of filtered file name or File object in a directory.
