THe required code is given below:
Explanation:
import java.util.Scanner;
public class TicketSeller {
public static int count=0;
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int order; //number of ticket ordered
int numberTickets; //total number of available tickets
System.out.println("Input the number of tickets you want to sell: ");
numberTickets = scanner.nextInt();
//continue until there are no tickets remaining
while (numberTickets>0)
{
System.out.println("\nInput requested tickets: ");
order = scanner.nextInt();
if (order<=numberTickets) //check if the ordered number is less than(or equal to) the available tickets
{
numberTickets= processOrder(order,numberTickets);
count++; //increase the count of number of buyers
}
else System.out.println("Too many tickets requested, please try again.");
}
System.out.println("You have had "+count+ " buyers.");
}
public static int processOrder(int order, int numberTickets){
Scanner scanner = new Scanner(System.in);
if(order>4) //check if order is more than 4
{
System.out.println("Too many tickets requested, please try again.");
System.out.println("\nInput requested tickets: "); //ask to input number of tickets again
order = scanner.nextInt();
numberTickets= processOrder(order,numberTickets);
count++; //increase the count of number of buyers
}
else
{
numberTickets=numberTickets-order; //subtract the number of ordered tickets from available tickets
System.out.println("Thank you for your purchase. There are "+numberTickets+ " tickets remaining.\n");
}
return numberTickets;
}
