Question

The Java program below does not continue to ask for user inputs when i tell the program that I have more customers. Can you please edit this program so that the program repeatedly accepts user inputs for several customers and call the user defined method to get the results until the user chooses not to. You can change it however you see fit as long as the program runs correctly and keeps asking for inputs. I use jGrasp for this program.

import java.io.*;
import java.util.Scanner;
class Firm
{

//create scanner object to represent keyboard
Scanner console = new Scanner(System.in);

public static double serviceTaxCalc(double hourlyRate, int consultingTime, double income)
{
if(income <= 25000)
{
consultingTime = (consultingTime > 30 ? consultingTime-30 : 0);
return hourlyRate/60 * .4 * consultingTime;
}
else
{
consultingTime = (consultingTime > 20 ? consultingTime-20 : 0);
return hourlyRate/60 * .7 * consultingTime;
}
}

public static void main(String[] args)
{

//declare variables
double hourlyRate, income;
int consultingTime;
boolean haveMoreCustomers = true;
Scanner console = new Scanner(System.in);

//User information
while(haveMoreCustomers)
{
System.out.print("Enter hourly rate: ");
hourlyRate = console.nextDouble();

System.out.print("Enter consulting time in minutes: ");
consultingTime = console.nextInt();

System.out.print("Enter income of the customer: ");
income = console.nextDouble();

System.out.println("The service to be paid is: "+serviceTaxCalc(hourlyRate, consultingTime, income));
System.out.print("Do you have more customers (yes/no): ");
haveMoreCustomers = console.nextBoolean();

}
}//end main
}//end class
