Creating code and I am stuck was looking for some help on what kind code..

Question

to put in to do the things I want to display.
This is a project for school and I have been searching everywhere for what to do. The assignment is to write a program that will randomly generate numbers for a Super 7 lottery. Each ticket is to display 3 sets of 7 numbers. The example we are given looks exactly like so
Ticket 1
23 12 34 12 25 13 21
1 2 3 4 5 6 7
etc etc etc etc
Anyway the part I am stuck on is getting my array to display ascending order (small to big)
I keep getting duplicate numbers and ive tried so many different parts of code to try and get no duplicate numbers
also I can't the output to look like it does above. If I print a new line it always seems to do this:
Ticket 1
1
2
3
4
5
6
7
8
9
etc
whereas I need it like the example I posted first.
Here is the code I have so far and I am wondering if I am approaching this right? An array is the correct way to do something like this right?
import java.util.*;
import java.util.Arrays;
public class Super72
     public static void main (String[] args)
     //create a scanner object
     Scanner input = new Scanner(System.in);
     //Display a title
     System.out.println("\n     Get your Super7 lottery numbers!\n");
     // Ask user how many tickets they purchased
     System.out.print("Enter the number of tickets you'd like to purchase: ");
     int numTickets = input.nextInt();
     //Display how many tickets user bought and a thank you
     System.out.print("\nThank you for your purchase! Here are your " + numTickets + " tickets:\n");
     //create an array for ticket 1
     System.out.println("\nTicket 1");
     int mySelect;
     int [ ] myArray = new int [7];
     java.util.Arrays.sort(myArray);
     for(int i=0; i < myArray.length; i++)
          mySelect = (int) (Math.random() * 47 + 1);
          myArray[i] = mySelect;
          }//end of for loop
     }//end main
}//end classEdited by: KRollinz on Nov 11, 2007 11:30 AM

Answer 1

GOT IT!! well sort of. I got my code to display 1 line of 1 ticket in order and no duplicates!!!
Now I am stuck what should I be doing to get 3 lines? I already created 2 other arrays but when i output it cmd just sort of sits there and doesnt do anything so im not sure what that problem is.
How should I approach outputting 2 more random lines?
import java.util.*;
public class SuperSeven
     public static void main (String[] args)
     //create a scanner object
     Scanner input = new Scanner(System.in);
     //Display a title
     System.out.println("\n     Get your Super7 lottery numbers!\n");
     // Ask user how many tickets they purchased
     System.out.print("Enter the number of tickets you'd like to purchase: ");
     int numTickets = input.nextInt();
     //Display how many tickets user bought and a thank you
     System.out.print("\nThank you for your purchase! Here are your " + numTickets + " tickets:\n");
     System.out.print("\nTicket 1\n");
     System.out.print("        ");
     //Array 1
     int [ ] myIntArray1 = new int [7];
          for (int i=0;i<myIntArray1.length;i++)
          myIntArray1= (int)(47*Math.random() + 1);
               for(int check= 1 ; check < i; check++)
               if(myIntArray1[i]== myIntArray1[check])
          i--;
     //Array 2
     int [ ] myIntArray2 = new int [7];
          for (int a=0; a<myIntArray2.length; a++)
          myIntArray2[a]= (int)(47*Math.random() + 1);
               for(int check= 1 ; check < a; check++)
               if(myIntArray2[a]== myIntArray2[check])
          a--;
     //Array 3
     int [ ] myIntArray3 = new int [7];
          for (int b=0; b < myIntArray2.length; b++)
          myIntArray3= (int)(47*Math.random() + 1);
               for(int check= 1 ; check < b; check++)
               if(myIntArray2[b]== myIntArray3[check])
          b--;
          for (int i=0;i<myIntArray1.length;i++)
               Arrays.sort(myIntArray1);
               System.out.print(myIntArray1[i] + "\t");
