import java.util.Scanner;

public class BillingRecordException {

public static void main(String[] args) {
  
int numDoc = 0, numPat = 0;
Scanner keyboard = new Scanner(System.in);

//1 - prompt user to enter length of docArray (numDoc) and patArray (numPat) - Exception
System.out.print("Enter number of doctors in the facility: ");
numDoc = keyboard.nextInt();

  
System.out.print("Enter number of patients in the facility: ");
numPat = keyboard.nextInt();

//2- create Doctor array and Patient array
Doctor[] docArray = new Doctor[numDoc];
Patient[] patArray = new Patient[numPat];
  
//3 - create each element of these two arrays
System.out.println("-----------------------------");
System.out.println("Create Doctor Array:");
System.out.println("-----------------------------");

  
//loop
for(int i = 0; i < numDoc; i++)
{
keyboard.nextLine(); //get rid of newline

System.out.println("Doctor " + (i+1));
// prompt user: name, specialty, fee - controling statement and exception
System.out.print("Enter doctor's name: ");
String name = keyboard.nextLine();
System.out.print("Enter Specialty: ");
String speciality = keyboard.nextLine();
System.out.print("Enter office visit fee: ");
double fee = keyboard.nextDouble();


// create a Doctor object
docArray[i] = new Doctor(name, speciality, fee);
}
  
  
//4- loop
System.out.println("-----------------------------");
System.out.println("Create Patient Array:");
System.out.println("-----------------------------");

for(int i = 0; i < numPat; i++)
{
keyboard.nextLine(); //get rid of newline
System.out.println("Patient " + i);
System.out.print("Enter Patient's name: ");
String name = keyboard.nextLine();
System.out.print("Enter Patient ID: ");
int id = keyboard.nextInt();
patArray[i] = new Patient(name, id);
}
  
// prompt user for doctor and patient index - exception
int dIdx, pIdx;
  
String ans;
do
{
System.out.print("Enter Patient index: ");
pIdx = keyboard.nextInt();
System.out.print("Enter Doctor index: ");
dIdx = keyboard.nextInt();
// create a Billing object
Billing bill = new Billing(docArray[dIdx], patArray[pIdx]);
// prompt user
System.out.print("Do you want to set another appointment? (y/n): ");
ans = keyboard.next();
}while(ans.equalsIgnoreCase("y"));
  
//5 - display method Doctor class
System.out.println();
for(int i = 0; i < numDoc; i++)
docArray[i].display();

}

}
