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);
