Class FileFilter

java.lang.Object
javax.swing.filechooser.FileFilter
Direct Known Subclasses:
BasicFileChooserUI.AcceptAllFileFilter, FileNameExtensionFilter
public abstract class FileFilter extends Object
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.
