I need a 80% or higher on this! Java question and need help!

Part A:

Open the file BloodData.java 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. Include get and set methods for each field. Open the file TestBloodData.javaand click the "Run Code" button to demonstrate that each method works correctly.

Part B:

Open the file Patient.java which 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 to O and +. Create an overloaded constructor that provides values for each field. Also provide get methods for each field. Open TestPatient.java. Click the green "Run Code" button at the bottom of your screen to demonstrate that each method works correctly.
