Have a look at the standard loop patterns in
http://mindprod.com/jgloss/javacheat.html#LOOPS

_for_ is tricky. Every one of the semicolons has to be just so. Often
the compiler does not warn you in an intelligible way if you misplace
them. One of my favourite errors is to put a ; after the ++. Normally
in Java ; is a terminator not a separator.

Couple thoughts.

_a_ is not a very good name for a length variable.
Why did you compute it then never use it?
