Question

I am making an application to store tickets for boarding a place for a imaginary airline. I have created a Ticket class see below ``` public class ticket { String lastName; String firstName; String origin; String destination; String flightNumber; String seatNumber; String date; public ticket() { } public ticket(String lastname, String firstName, String origin, String destination, String flightNumber, String seatNumber, String date) { } ``` I have two ticket classes, first and economy. The plane can only hold 10 seats. So my structure is having two arrays of ticket objects, one containing 4 ticket objects "first class" and one containing 6 ticket objects "economy class". See below ``` ticket[] ticketFirst = new ticket[4]; ticket[] ticketEcon = new ticket[6]; ``` I have to assign the seats randomly within their respective ticket arrays. I am calling my get method (example below) to check for duplicates, that is, that the randomly assigned seat is already filled or not. `public String ge…

Your `ticket[rand]` needs to be either `ticketFirst[rand]` or `ticketEcon[rand]`. They also need to be defined outside of the Form1 constructor to be able to access them elsewhere in the form.

e.g.

```
public partial class Form1 : Form
{
    ticket[] ticketFirst = new ticket[4];
    ticket[] ticketEcon = new ticket[6];

public Form1()
    {
        InitializeComponent();
        ticketFirst = new ticket[4];
        ticketEcon = new ticket[6];  
    }

private void btnSubmit_Click(object sender, EventArgs e)
    {
        Random random = new Random();
        int rand = random.Next(0, 4);
        if (ticketFirst[rand].getLastName = null)
        {
            ticketFirst[rand].setLastName = txbLastName.Text;
            ticketFirst[rand].setFirstName = txbFirstName.Text;
            ticketFirst[rand].setOrigin = txbOrigin.Text;
            ticketFirst[rand].setDestination = txbDestination.Text;
            ticketFirst[rand].setFlightNumber = txbFlightNumber.Text;
            ticketFirst[rand].setSeatNumber = txbSeatNumber.Text;
            ticketFirst[rand].setDate = txbDate.Text;
        }
        else
        {                
            MessageBox.Show("Seat Assignment Failed, try again.", "Seat Assignment");
        }
    }
}
```
