I have a few related classes which throw a DataException from the
constructor if the data passed is invalid.  I can't exactly say that the
data validation is exactly the same for these classes, but they're
similar.  Basically, count the number of String[] elements, try to parse
Integer or Float values and so forth; there's some overlap.

What's the standard approach?  Multiple anonymous inner classes?   A
static utility class?  Verify the data before sending it to the
constructor?

Or, create a DataValidator class which the constructor instatiates?

thanks,
