OurComparable Dog
Create a class called Dog
that implements the OurComparable
interface.
Dog
should provide a public constructor that takes a single Double
argument that sets that dog's weight.
You should assert that the provided weight is greater than zero.
Do not expose the weight property.
You should order dogs based on their weight from lightest to heaviest.
Specifically, compareTo
should return:
- -1 if this dog is lighter than the passed dog
- 0 if this dog is the same weight as the passed dog
- 1 if this dog is heavier than the passed dog
If the passed value is not a Dog
, throw an IllegalArgumentException
.
As a reminder, the OurComparable
interface comprises a single method: fun compareTo(other: Any?): Int
.
