    Exclamation im i on the righ tracks

    for our coursework we had to make a lottery random number ticket generator

    The Numbers class should provide the following functionality:
     Generates 6 random numbers in a range 1 to 49.
     Write YOUR OWN custom method incorporating an algorithm to sort the numbers in ascending order.
     Store the 6 numbers in a fixed-sized collection (array).
     Format and display the numbers (number output in the range 1 to 9 should be preceded by a blank space).

    The Ticket class should provide the following functionality:
     Construct a Lottery Ticket that allows the customer to have as many randomly generated Lucky Dips as they require on the same ticket.
     Store the ‘Lucky Dip’ number sets in a flexible-sized collection (array list).
     Display the ticket and ‘Lucky Dip’ numbers to the screen in the correct format.

    i have started with the numbers class and my question is that im i on the right path also can anyone guide me because somewhere i need a loop

    //access to the java.utill.random libary.
    import java.util.Random;
    /**
    * Lucky dip lottery ticket system.
    * @author Daniel Prempeh
    * @version 1.1 2013
    */

    public class Numbers
    {
    private int[] Lotto;
    private final int MAX=6;

    public Numbers()
    {
    Lotto = new int[MAX];
    }

    public void generateNums(int qty)
    {
    //assign random value to 6 lines of intergers.
    Lotto[0] = 1 + (int) (Math.random() * 49);
    Lotto[1] = 1 + (int) (Math.random() * 49);
    Lotto[2] = 1 + (int) (Math.random() * 49);
    Lotto[3] = 1 + (int) (Math.random() * 49);
    Lotto[4] = 1 + (int) (Math.random() * 49);
    Lotto[5] = 1 + (int) (Math.random() * 49);
    //Print out the line of numbers.
    System.out.println(Lotto[0] + ", " + Lotto[1] + ", " + Lotto[2] + ", " + Lotto[3] + ", " + Lotto[4] + ", " + Lotto[5]);
    }
    }

    where is the main method?
    to print the values of an array Lotto[],
    use
    for(int i=0;i<MAX;i++)
    {
    System.out.println(Lotto[i]);
    }

    i guess the variable int qty on the line
    public void generateNums(int qty) {...}
    was not used
