Give the definition of a class named Doctor whose objects are records for a clinic's doctors. This class will be a derived class of the class SalariedEmployee (covered in class and also in Chapter 7 of the text.) A Doctor record has the doctor's specialty (such as "Pediatrician", "Obstetrician", "General Practitioner", and so forth: so use the type String) and office visit fee (use type double.) Be sure your class has a resolvable complement of constructors, accessor and mutator methods, and suitably defined equals and to String methods. Write a program to test all of your methods. Submission Requirements: Submit the aforementioned files in a zip file with the naming strategy: First initial + last name + PS + problem set number.zip As an example, I would submit the code in a zip file named mmeluskyPSl.zip. Submit your zip file via the "Problem Set 1" Canvas dropbox before the date of the close of the assignment
