FileFilter
is an abstract class used by JFileChooser

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.
