FileFilter is an abstract class that has no default implemention. A FileFilter, once implemented, can be set on a JFileChooser to keep unwanted files from appearing in the directory listing. For an example implementation of a simple file filter, see yourSDK/demo/jfc/FileChooserDemo/ExampleFileFilter.java. For more information and examples see How to Use File Choosers, a section in The Java Tutorial.
