Create a class named BloodData that includes fields that hold a blood type ( the four blood types are O, A,B, and AB) and an Rh factor( the factors are + and -). Create a default constructor that sets the fields to O and +, and an overloaded constructor that requires values for both fields. Also you need to write accessors and mutators for each field and of course, a display method.
