Question

Starting out with java early objects(with the pea on the front).  page 348 PC#15 I've managed to get the program to conpile but when I run the program I get the io exception below.  I thought that this exception was impossible with the throws IOException clause.  can you please take a look and let me know what I am doing wrong.  thanks
