ArrayList and Iterator problems!! Lotto Machine

I am trying to write the ticket class for a lotto ticket machine. I have created a Number class but I am having trouble with the Ticket class, my code is below if anyone can help!!!
import java.util.ArrayList;
import java.util.Iterator;

/**
* Class Ticket.
* Builds a Lucky Dip Lotto Ticket.
* Creates an arrayList of Lucky Dip numbers then displays the ticket and numbers to the screen.
*
* @author #############
* @version ############
*
* Note : The following is only a suggested set of fields, constructors and methods,
* candidates may design their own class if they wish.
*
*/
public class Ticket
{
private int numberOfLines;
private ArrayList lotoLines;

// Constructor : Creates an arrayList of Lucky Dip numbers, takes one argument to load the numberOfLines field.

/**
* Creates an arrayList of Lucky Dip numbers,
* takes one argument to load the numberOfLines field.
*/
public Ticket()
{
lotoLines = new ArrayList();
numberOfLines = 1;
}

// Method : Display the ticket details and the list of Lucky Dip numbers to the screen.

/**
* Show the ticket details and list the list of Lucky Dip numbers to the screen.
*/
public void showNumbers()
{
Iterator it = lotoLines.iterator();
while(it.hasNext()){
Numbers lotoLines = (Numbers) it.next();
System.out.println(lotoLines.toString());
}
}




}

In the future, try wrapping your code in [code][/code] tags when posting the forum.

Can you explain further?
What happens when your Ticket class is run?
"What do you expect it to do" vs "What does it do"

This will save us from having to compile the code and create a test class

Hi,
I want to have as many randomly generated Lucky Dips as required
on the same ticket.
I have constructed the numbers class which generates the random numbers. I now need
to link the Ticket class to the numbers class to store the Lucky Dip number sets in a flexible-sized collection(array list)
Display the ticket and the Lucky Dip numbers to the screen in the correct format,
this will Allow an output for a ticket with five lucky dips and an output for a ticket
with three lucky dips.
Thank you in advance for your help
