Now within the same class lets create a constructor for passing the data to the POJO:

    public Donor(String fullName, String email, String city, String bloodGroup) {        FullName = fullName;        Email = email;        City = city;        BloodGroup = bloodGroup;    }    public String getFullName() {        return FullName;    }    public void setFullName(String fullName) {        FullName = fullName;    }    public ...
