- * A convenience implementation of FileFilter that filters out

- *
- * Extensions are of the type ".foo", which is typically found on
- * Windows and Unix boxes, but not on Macinthosh. Case is ignored.
- *
- * Example - create a new filter that filerts out all files
- * but gif and jpg image files:
- *
- * JFileChooser chooser = new JFileChooser();
- * DefaultFileFilter filter = new DefaultFileFilter(
- * new String{"gif", "jpg"}, "JPEG & GIF Images")
- * chooser.addChoosableFileFilter(filter);
- * chooser.showOpenDialog(this);
