Create a generic class that can compute the average of an array of numbers of any given type.

  

class Stats<T> {
  T[] nums;

  Stats(T[] o) {
    nums = o;
  }

  double average() {
    double sum = 0.0;

    for (int i = 0; i < nums.length; i++)
      sum += nums[i].doubleValue(); // Error!!!

    return sum / nums.length;
  }
}
