Determine how many times str2 has appeared in STR:

Limit the range of random numbers:

        New Random ();                 int New int [Ten];                  for (int i=0;i<arr.length;i++)        {            // limit the range of generated random numbers            arr[i] = r.nextint (221) +2                ; + " ");        }
