Define a class named Doctor whose objects are records for a clinic's doctors. Derive this class from the class Person given in Lesson. 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 an office-visit fee (use the type double). Give your class a reasonable complement of constructors and accessor methods. Write a driver program to test all your methods.

Following is defined the required class having accessor methods and test program:

Explanation:

class Person

{

private String doc_name;

public Person (String doc_name)

{

this. doc_name = doc_name;

}

public String getDoc_Name ()

{

return doc_name;

}

}

class Doctor extends Person

{

private double office_visit_fee;

private String Specialty;

public Doctor (String doc_name, double office_visit_fee, String Specialty)

{

super (doc_name);

this. office_visit_fee = office_visit_fee;

this. Specialty = Specialty;

}

//accessor methods

public double getOffice_Visit_Fee ()

{

return office_visit_fee;

}

public String getSpecialty ()

{

return Specialty;

}

public String toString ()

{

return "Doctor Name "+getDoc_Name () + " Office Visit Fee : $"+office_visit_fee+

" Specialty : "+Specialty;

}

}

class Test

{

public static void main (String[] args)

{

Doctor dctr = new Doctor ("Joseph Lister",134.56,"Obstetrician");

System. out. println (dctr);

}

}

Output:

Doctor Name Joseph Lister Office Visit Fee : $134.56 Speciality : Obstetrician
