I copied and pasted this code from the Sun Java Tutorial

A lot of sun's example code makes questionable
decisions about what to leave out, for the sake
of brevity. I leave it to others to argue whether this
omission constitutes buggy code, but I for one would
usually not recommend 'swallowing exceptions' as
this code does.
....

public class ImageLabel extends Component {

...

     public static void main(String args[]) {

       JFrame frame = new JFrame("Image Label");
       BufferedImage img = null;
       try {
           String imageFileName = "painting.gif";
           img = ImageIO.read(new File(imageFileName));
       } catch (IOException e) {

   // either dump exceptions, or justify (in a comment) why they
   // can be ignored!
   e.printStackTrace();
....

<Output>
javax.imageio.IIOException: Can't read input file!
        at javax.imageio.ImageIO.read(ImageIO.java:1275)
....
</Output>
