Is there a way to make my program parse a bunch of files? Design advice!

Question

Hello everyone.
Currently my program does parses up a file and spits out a new file (its more complicated than that but in a nut shell thats what it does).
The main function looks like this:
package corysanchez.rodmload;
public class Main
     public static void main(String [] args)
          ConversionTableParser classNameFile = new ConversionTableParser();
          classNameFile.parseFile("classNameConversion.txt");
          JavaParser javaFile = new JavaParser();
          javaFile.parseFile("interface.txt");
}If you look at this code, that interface.txt is 1 file its parsing and its generating a new file called INTERFACE.SMP once this program is done running.
Now what if there was a whole directory of files I want to run this program with?
Like I want to pass in via command line, a directory, and I want my program to Search that directory and Run every file in that directory through my program.
So my program would see
javaFile.parse("file1.txt");
javaFile.parse("file2.txt");
javaFile.parse("file3.txt");
etc...
I wrote this program in Rexx and I'm rewriting it in Java. How I did it in Rexx was I created a script that would Search a directory, and call the whole program and just pass in an array of file names it found.
Like if my above program was called Parser.exe.
I would call Parser.exe <pass it an array of file names>
then inside Parser.exe it would run the javaFile.parse(file1.txt);
I was hoping there was a better method on how to accomplish this in java rather than writing another java program and calling this program via command line.
Thanks!

If you declare the file using the directory instead of a filename, you can use
File directoryInQuestion = new File("./yourdirectory");
File[] allTheFiles = directoryInQuestion.listFiles();
for ( int i = 0; i < allTheFiles.length(); i++ ){
   if ( allTheFiles.isFile() )
do whatever to allTheFiles[i]
Hope that's helpful :D
