compareTo method

@override int compareTo(Date other)

Compares this object to another object.

Returns a value like a Comparator when comparing this to other. That is, it returns a negative integer if this is ordered before other, a positive integer if this is ordered after other, and zero if this and other are ordered together.

The other argument must be a value that is comparable to this object.

Implementation

@override
int compareTo(Date other) {
  int d = year.compareTo(other.year);
  if (d != 0) {
    return d;
  }
  d = month.compareTo(other.month);
  if (d != 0) {
    return d;
  }
  return day.compareTo(other.day);
}
