Hi, I am having a tremendous amount of trouble in my computer science class! We are doing java and I just feel like I am so behind and I can't understand what my teacher is talking about. Anyway, we are assigned a program assignment that I have been working on for days and I cannot get to work. The program is due tomorrow!
I also noticed someone else had already posted this same program problem but the replies didn't help my specific problems
The assignment is :
The manage of a football team wants you to write a program that calculates the total ticket sales after each game. There are four types of tickets-- box, sideline, premium, and general admission. After each game, the data is stored in a file in the following form:
ticket price numberOfTicketsSold
sample data
250 5750
100 28000
50 35750
25 18750
The first line indicates that the box ticket price is $250 and that 5,570 tickets were sold at that price.
Output a table that shows the number of tickets sold and the sales amount for each ticket type followed by a total line showing the overall number of tickets sold and overall sales amount.
I have constantly been looking at examples in my book but I dont understand how to do this inputing a file. My file with the sample data in it is called ticketSales.dat
I asked the user to input data but maybe im not supposed to do that because I'm supposed to use the file? But I dont know how?
This is my code:
CODE
import javax.swing.JOptionPane;
import java.io.*;
public class TicketSales
{
public static void main(String[] args)
{
String inputStr;
String outputStr;
int noOfTicketsSoldBox;
int noOfTicketsSoldSideline;
int noOfTicketsSoldPremium;
int noOfTicketsSoldGeneral;
double totalSaleAmountBox;
double totalSaleAmountSideline;
double totalSaleAmountPremium;
double totalSaleAmountGeneral;
int totalTicketsSold;
double totalSalesAmount;
Scanner input =
new Scanner("ticketSales.dat");
inputStr = JOptionPane. showInputDialog
("Please enter the total number of tickets sold for Box Seat Admission");
noOfTicketsSoldBox= Integer.parseInt(inputStr);
inputStr = JOptionPane. showInputDialog
("Please enter the total number of tickets sold for Sideline Seat Admission");
noOfTicketsSoldSideline = Integer.parseInt(inputStr);
inputStr = JOptionPane. showInputDialog
("Please enter the total number of tickets sold for Premium Seat Admission") ;
noOfTicketsSoldPremium = Integer.parseInt(inputStr);
inputStr = JOptionPane. showInputDialog
("Please enter the total number of tickets sold for General Admission");
noOfTicketsSoldGeneral = Integer.parseInt(inputStr);
totalSaleAmountBox = noOfTicketsSoldBox * 250;
totalSaleAmountSideline = noOfTicketsSoldSideline * 100;
totalSaleAmountPremium = noOfTicketsSoldPremium * 50;
totalSaleAmountGeneral = noOf
icketsSoldGeneral * 25;
totalTicketsSold = noOfTicketsSoldBox + noOfTicketsSoldSideline + noOfTicketsSoldPremium + noOfTicketsSoldGeneral;
totalSalesAmount = totalSaleAmountBox + totalSaleAmountSideline + totalSaleAmountPremium + totalSaleAmountGeneral;
outputStr = "Number Of Box Tickets Sold: "
+ (noOfBoxTicketsSold) + "\n"
+ "Box Total: $"
+ String.format("%.2f", totalBoxSaleAmount) + "\n"
+ "Number Of Sideline Tickets Sold: "
+ (noOfSidelineTicketsSold) + "\n"
+ "Sideline Total: $"
+ String.format("%.2f", totalSidelineSaleAmount) + "\n"
+ "Number Of Premium Tickets Sold: "
+ (noOfPremiumTicketsSold) + "\n"
+ "Premium Total: $"
+ String.format("%.2f", totalPremiumSaleAmount) + "\n"
+ "Number Of General Tickets Sold: "
+ (noOfGeneralTicketsSold) + "\n"
+ "General Total: $"
+ String.format("%.2f", totalGeneralSaleAmount) + "\n";
+ "Number Of Total Tickets Sold: "
+ (totalTicketsSold) + "\n"
+ "Total Sales Amount: $"
+ String.format("%.2f", totalSalesAmount) + "\n";
JOptionPane.showMessageDialog(null, outputStr,
"Football Ticket Sales",
JOptionPane.INFORMATION_MESSAGE);
System.exit(0);
}
}
When I have tried to put it in my command prompt the error reads :
TicketSales.java:72:not a statement
+ String.format("%.2f", totalSalesAmount) + "\n";
^
1 error
Even though theres only one error I think I'm not doing the program as assigned!
I am so confused so if anyone could help me with my problem it would be extremely appreciated!!!
Thanks!
