6. A car dealership needs a program to store information about the cars for sale. For each car, they want to keep track of the following information: number of doors (2 or 4), whether the car has air conditioning, and its average number of miles per gallon. Which of the following is the best design? (a) Use one class, Car, which has three data fields: int numDoors, boolean hasAir, and double milesPerGallon. (b) Use four unrelated classes: Car, Doors, AirConditioning, and MilesPerGallon. (c) Use a class Car which has three subclasses: Doors, AirConditioning, and MilesPerGallon. (d) Use a class Car, which has a subclass Doors, with a subclass AirConditioning, with a subclass MilesPerGallon. (e) Use three classes: Doors, AirConditioning, and MilesPerGallon, each with a subclass Car.
Homework Answers

2. Design two programs named BaseClass and SubClass. In BaseClass, define a variable xVar (type: char, value: 65), and a method myPrint to print xVar. SubClass is a subclass of BaseClass. In SubClass, define a variable yVar (type: int, value: 16) and another variable strVar (type: String, value: "java program!"). There is also a method myPrint to print the value of yVar and strVar in SubClass, as well as an additional method printAll, in which...

A liter is 0.264179 gallons. Write a program that will read in the number of liters of gasoline consumed by the user's car and the number of miles per gallon the car delivered. Your program should allow the user to repeat this calculation as often as the user wishes. Define a function to compute the number of miles per gallon. Your program should use a globally defined constant for the number of liters per gallon. After doing this... Modify your...
