Is there a way to loop through all the files in a directory without knowing their names?

Thanks!

File dir = new File("the_dir");
File[] files = dir.listFiles();
for (int i = 0; i < files.length; i++) {
System.out.println(files);
}

You should use a recursive method to loop through all subdirectories ...

Thanks!
Is there a way to take files only of a certain extension, rather than loading them all in and checking?

Implement the FileFilter class, and use the File.listFiles(FileFilter filter) method.

Thank you!

Is there any better way to do this than

// ...
public boolean accept(File f)
{
  return (f.getName().endsWith(".ext"));
}
// ...

OK good. Just wondering if RegEx would be better...
