```
public final class FileNameExtensionFilter
extends FileFilter
```
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);
 
```
Since:

1.6
