Swing:FileFilter

• First of all create a subclass of FileFilter as follows:
• Following subclass of FileFilter will allow the JFileChooser to show only gif files or folders.

public class GifFilter extends FileFilter{

   public boolean accept(File f){

      return f.getName().toLowerCase().endsWith(".gif") || f.isDirectory();

   }

   public String getDescription(){ return "GIF Image";}

}

Once we have a file filter object, we can use the setFileFilter() method of the JFileChooser class to install it into the JFileChooser object.

fileChooser.setFileFilter(new GifFilter());
