You should learn how to debug your own programs, it's an important part 
of programming.

My guess is in the line above the pattern "." was not found and 
findInlIne() returned null:

"If no such pattern is detected in the input up to the next line 
separator, then null is returned"

<http://download.oracle.com/javase/6/docs/api/java/util/Scanner.html#findInLine%28java.util.regex.Pattern%29>

I'll let you discover how to verify that this is indeed the problem, and 
what to do about it.
