On the following line:

Image = new URL(getDocumentBase(),String.valueOf(i+1)+ ".jpg");

Why does it throw a 'MalformedURLException'?  Is there a way to set the
image on a jbutton using a japplet without a try,catch block?

The URL constructor will throw that exception if you provide an invalid url

try:

Image = getClass().getResource("/"+String.valueOf(i+1)+ ".jpg");

That works, so is java incapable of throwing an exception without catching it?

correct, if a method declares that it throws a (checked) exception the calling method must catch it or declare that it may throw it.(RuntimeExceptions are nopt checked)
