1. 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 Oand +, and an overloaded constructor that requires values for both fields. Include get and set methods for each field.
2. Create a class named Patient that includes an ID number, age, and BloodData. Provide a default constructor that sets the ID number to 0, the age to 0, and the BloodData values to O and +. Create an overloaded constructor that provides values for each field. Also provide get methods for each field.
