Solve: OurComparable Car

Created By: Geoffrey Challen

/ Version: 2023.10.0

Create a class called Car that implements the OurComparable interface. Car should provide a public constructor that takes a single int argument that sets that car's odometer. You should assert that the provided int is not negative. Do not expose the odometer variable.

You should order cars based on their odometer reading, from least to greatest. Specifically, compareTo should return:

• -1 if this car has a lower odometer reading than the passed car
• 0 if this car has the same odometer reading as the passed car
• 1 if this car has a higher odometer reading than the passed car

If the passed value is not a Car, throw an IllegalArgumentException.

As a reminder, the OurComparable interface comprises a single method: int compareTo(Object other).
