• create an integer count and set it initially to 0;
• now do the following 1,000 times:
  • populate the array with random integers in the range 1 to 6;
  • increase count by 1;
  • test using the method hasNoDuplications to see if the array has any repeated integers;
  • continue doing this until there are no repeated integers;
