       int arr[][] = new int[100][2];
       int size = getProductsAndPrices(arr);
       displayProducts(arr, size);

   }

   private static void displayProducts(int[][] aArr, int aSize) {
       for (int i = 0; i < aSize; i++)
           System.out.println(aArr[i][0] + " : " + aArr[i][1]);
   }

   private static int getProductsAndPrices(int[][] arr) {
       int size = 0;
       for (int i = 0; i < 100;) {

               break;
