1. ExampleFileFilter
* A convenience implementation of FileFilter that filters out* all files except for those type extensions that it knows about.
*
* 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();
* ExampleFileFilter filter = new ExampleFileFilter(
* new String{"gif", "jpg"}, "JPEG & GIF Images")
* chooser.addChoosableFileFilter(filter);
* chooser.showOpenDialog(this);
