Define a class named Doctor whose objects are records for cl

Define a class named Doctor whose objects are records for clinic’s doctors. Derive this class from the class Person given in listing 8. A Doctor record has the doctor’s name—defined in the class Person—A specialty as a string (for example Pediatrician, Obstetrician, General Practitioner, and so on), and office visit fee (use type double). Give your class has a reasonable complement of constructors, accessor methods and an equals method as well. Write a driver program to test all your methods.
