//-----------Start below here. To do: approximate lines of code = 4
// write a method to implement the Comparable interface
// The method should compare two cars based on fuel efficiency (higher fuel efficiency is better)






//-----------------End here. Please do not remove this comment. Reminder: no changes outside the todo regions.

public String toString()
{
return "Name: " + name + " Gas Level: " + gasLevel + " FuelEfficiency: " + fuelEfficiency;
}
}

P.s: please besides the code, also include a screenshot of code, and the output to confirm code doesn't get edited out and the output satisfies the problem!!

See the following files: CarSorter.java * Car.java (has todo) Approximate total lines of code required: 4
