Why not just have an isNull(propertyName) method rather than litter classes with hasSpouse, hasX, has Y?

If you're going to call getSpouse(), you should already know that the person has a spouse. You shouldn't call getSpouse() and then check the result to see if a the person had a spouse. Nor should you call getSpouse() and look for an exception to let you know that person didn't have a spouse. Patrick's was one of the best explanations I have seen so far.
