Thread: I had to write a code for a total ticket sales with filling int the information given in the book but my code doesn't run for some reason

ticketprice numberOfTicketsSold
250 5750
100 28000
50 35750
25 18750

import java.io.FileReader;
import java.io.IOException;
import java.util.Scanner;
import java.text.NumberFormat;
 
class TotalTicketSales {
	public static void main(String [] args) throws IOException{
		int ticketPrice, ticketsSold, ticketTotal;
		double totalSale;
 
		Scanner inFile = new Scanner(new FileReader("tickets.dat"));
 
		ticketPrice = inFile.nextInt(250);
		ticketsSold = inFile.nextInt(5750);
		ticketTotal = ticketsSold;
		totalSale = ticketPrice * ticketsSold;
 
		ticketPrice = inFile.nextInt(100);
		ticketsSold = inFile.nextInt(28000);
		ticketTotal += ticketsSold;
		totalSale += ticketPrice * ticketsSold;
 
		ticketPrice = inFile.nextInt(50);
		ticketsSold = inFile.nextInt(35750);
		ticketTotal += ticketsSold;
		totalSale += ticketPrice * ticketsSold;
 
		ticketPrice = inFile.nextInt(25);
		ticketsSold = inFile.nextInt(18750);
		ticketTotal += ticketsSold;
		totalSale += ticketPrice * ticketsSold;
 
		NumberFormat nf = NumberFormat.getCurrencyInstance();
 
		System.out.println("Total Sales " + nf.format(totalSale));
		System.out.println("Total Tickets Sold " + ticketTotal);
 
		inFile.close();
	}
}

Yes my question is why does my code not give me any output? It is suppose to output total sales amount and total amount of tickets sold.

it says it cant locate my ticket.dat but its their so I need a way to let it run itself off the info i provided instead of the dat. Not exactly sure what i'd have to change now. Any advice?

If I want to run the code without having to use a dat file with the information I already have within the code how should I alter it to do so? I believe my code is to be used by itself. I don't think they want me use anything outside to the code to produce the desired output. So to reiterate how would i have to alter my code to produce the output without the need of anything outside it simple input output within the code with the information I provided? Again thank you for helping me.
