I am pretty ignorant of this language. I am working from a '...for dummies' book to teach myself and after the first few pages I have already stumbled upon a problem. I have attached a code, pretty simple one, which I'm trying to run but there are some errors and I don't know how to resolve them. I am using eclipse and when I debug I get a message which says 'program file does not exist.' If someone can help me with this I would appreciate it.
