scanning folders in Java using foreach loop

I think I got it. Use double loop. No recursion necessary (it is hidden in tree() method).

import static com.myjavatools.lib.Files.*;

..........

    for (File dir : tree(new File("."))) {
      System.out.println(dir);
      for (File f : files(dir)) {
        System.out.println("  " + f);
      }
    }
