Code:

		File[] list = folder.listFiles(new FileFilter() {
			@Override
			public boolean accept(File file) {
				if (file.isDirectory())
					return true;
				return false;
			}
		});

As you can see in those few lines i AM creating a FileFilter, in this portion specifically:

Code:

			@Override
			public boolean accept(File file) {

Is where i override accept(File file).

And yeah, thats the right way to use it, calling iterate will loop trough all the folders, printing them to command line.
