I'm guessing that the goal of the exercise is to generate random 
addition and subtraction problems for homework or testing. Instead 
of a constructor, perhaps a static factory method might be in 
order:

An acquaintance was always amused when her online math homework 
posed an exact duplicate. Because the problem space is small, it 
might be possible to construct a complete List<Problem> and use 
Collections.sort() to avoid repetition.
