Sample text

A class can even make use of multiple interfaces to allow for different manners of interaction. In the example that we have used throughout this chapter, the monster_truck class and its class hierarchy define what a monster_truck is; what it can and cannot do. A monster truck, however, can be used in other ways. For instance, a monster truck sitting at a car lot must be inventoried, inspected and categorized according to various characteristics, including price. The system responsible for managing the lot’s inventory does not care one bit about interacting with a monster truck in the way that a driver would, nor does it care whether or not it is managing a monster truck at all.

1 Classes Versus Objects Objects are instances of classes. It seems natural, then, to say that classes can be thought of as parents to objects. This logic, however, misses a fundamental point in the object-oriented paradigm. To say that classes are related to objects as parents are related to children suggests that classes and objects are the same type of entity, in the way that a parent and his or her child are both human beings. This is not accurate. Rather, using the same example, a class can be thought of as the DNA of an object.

This type of class is called an abstract class and is not meant to ever be instantiated (that is, no object will be created from it). Rather, it exists only to pass on common characteristics to more specific versions of itself. In our example, these would be characteristics or important information common to all trucks, such as numberOfWheels, allWheelDrive or groundClearance. Each subclass of truck might then add more specific characteristics in their separate implementations. Monster truck, for instance, might include a crushCar method and a paintJob attribute.
