DirectoryFileFilter

public class DirectoryFileFilter extends AbstractFileFilter implements Serializable
This filter accepts Files that are directories.

For example, here is how to print out a list of the current directory's subdirectories: 

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