javax.swing.filechooser.FileNameExtensionFilter
| FileNameExtensionFilter | | final public class FileNameExtensionFilter extends FileFilter (Code) | | An implementation of
FileFilter that filters using a
specified set of extensions. The extension for a file is the
portion of the file name after the last ".". Files whose name does
not contain a "." have no file name extension. File name extension
comparisons are case insensitive.
The following example creates a
FileNameExtensionFilter that will show
jpg files:
FileFilter filter = new FileNameExtensionFilter("JPEG file", "jpg", "jpeg");
JFileChooser fileChooser = ...;
fileChooser.addChoosableFileFilter(filter);
