compareTo method
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.
