To define a class that will represent a car, which of the following definitions is most appropriate?
a) private class car
b) public class car
c) public class Car
d) public class CAR
e) private class Car
Answer: c. Explanation: Classes should be defined to be public so that they can be accessed by other classes. And following Java naming convention, class names should start with a capital letter and be lower case except for the beginning of each new word, so Car is more appropriate than car or CAR.
