FileFilter is an abstract class used by JFileChooser for filtering the set of files shown to the user. See FileNameExtensionFilter for an implementation that filters using the file name extension. 

A FileFilter
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
yourJDK/demo/jfc/FileChooserDemo/ExampleFileFilter.java.
For more information and examples see
How to Use File Choosers,
a section in The Java Tutorial.
