Question

Must be in Java.

Please show step by step process with proper explanation and comments.

Please maintain proper indentation.

You are asked to create the starting point of a system to represent several types of medical doctors. You decided to implement two classes: a superclass Doctor and another subclass Hospital Doctor that inherits from the first class. In this problem you will: 1. Implement both Doctor and Hospital Doctor classes a. The Doctor class has the following: i. three String variables: Name, Phone, and Email (no gets or sets) ii. A constructor that initializes the class taking as parameters the three strings in the same order as described above. iii. A toString method that returns a well-formatted string representation of the object according to the example bellow b. The Hospital Doctor class inherits from Doctor and adds the following information: i. Two string variables: StaffNumber and Page Number ii. A constructor that receives all the information needed for the superclass plus StaffNumber and PageNumber iii. An overwritten toString method that returns the object's information according to the example below 2. Implement a test program which will: a. Read the name, phone and email and create a new Doctor Object b. Read the name, phone, email, staff number and pager number and create a new Hospital Doctor c. Print both objects according to the example. i. You must use the toString method to print the object's information.

CODE PROVIDED:

Answer 1

Doctor.java :

//Java class
public class Doctor {
   //String variables
   private String Name;
   private String Phone;
   private String Email;
   //constructor
   public Doctor(String name,String phone,String email)
   {
       this.Name=name;//set name
       this.Phone=phone;//set name
       this.Email=email;//set email      
   }
   //toString() method
   public String toString()
   {
       //return name , phone and email
       return this.Name+",phone:"+this.Phone+",email:"+this.Email;
   }

}

HospitalDoctor.java :

//Java class
public class HospitalDoctor extends Doctor {
   //String variables
   private String StaffNumber;
   private String PageNumber;
   //constructor
   public HospitalDoctor(String name,String phone,String email,String staffNumber,String pageNumber)
   {
       //calling base class constructor
       super(name,phone,email);
       this.StaffNumber=staffNumber;//set staff number
       this.PageNumber=pageNumber;//set page number  
      
   }
   //toString() method
   public String toString()
   {
       //return details
       return super.toString()+"\n Hospital doctor :staff #"+this.StaffNumber+",pager:"+this.PageNumber;
   }

}

Q1Runner.java :

import java.util.Scanner;//import package
//java class

public class Q1Runner {
   // main method, entry point of the class
   public static void main(String[] args) {
//object of Scanner class
       Scanner kb = new Scanner(System.in);
       // asking user name
       System.out.print("Enter Name :");
       String name = kb.nextLine();// reading name
       // asking user phone
       System.out.print("Enter Phone :");
       String phone = kb.nextLine();// reading phone
       // asking user email
       System.out.print("Enter Email :");
       String email = kb.nextLine();// reading email
       //creating Doctor object
       Doctor doctor=new Doctor(name,phone,email);
       System.out.print("Enter Name :");
       String name1 = kb.nextLine();// reading name
       // asking user phone
       System.out.print("Enter Phone :");
       String phone1 = kb.nextLine();// reading phone
       // asking user email
       System.out.print("Enter Email :");
       String email1 = kb.nextLine();// reading email
       // asking user Staff Number
       System.out.print("Enter Staff Number :");
       String staffNumber = kb.nextLine();// reading staff number
       // asking user page number
       System.out.print("Enter Page Number :");
       String pageNumber = kb.nextLine();// reading email
       //creating Doctor object
       HospitalDoctor hospitalDoctor=new HospitalDoctor(name1,phone1,email1,staffNumber,pageNumber);
       //printing Doctor objects
       System.out.println(doctor.toString());
       //print HospitalDoctor object
       System.out.println(hospitalDoctor.toString());
      
      

   }
}
