· Page 122: Delete the last sentence of the first full paragraph under Object-Oriented Programming Languages. Delete the second and third full paragraphs under Object-Oriented Programming Languages and replace with the following:
Every object is an instance of some class. That is, a class serves as a template for objects instantiated from it. An object’s class defines all the attributes defining the object, as well as all the messages to which the object will respond. Classes are typically arranged in a hierarchical structure, from superclasses to subclasses. The relationship between a superclass and a subclass is often called an IS-A link. These links show that subclasses inherit all behaviors and attributes defined by their superclass. Subclasses also contain behaviors and attributes of their own. A useful aspect of inheritance is that one can change attributes and behaviors in a superclass, and the changes will be reflected in all subclasses of that superclass.
Figure 4.10 shows an example of producing a paycheck. The Employee class has two subclasses: Contractor and Paid Weekly. Therefore, the Employee class is the superclass for the Contractor and Paid Weekly subclasses. The Paid Weekly class also has two subclasses, called Hourly and Salaried. The Paid Weekly class is the superclass of the Hourly and Salaried subclasses. Note that a class can be a subclass and a superclass simultaneously (e.g., Paid Weekly in our example).
In our example, the Paid Weekly class inherits the attributes of Name and Title and the Print behavior from the Employee class. The Paid Weekly class also has an additional behavior, Make_weekly_paycheck. The Hourly and Salaried subclasses inherit the Name and Title attributes from the Paid Weekly class. The Hourly subclass inherits the Print behavior from the Paid Weekly class. The Hourly subclass also has the attributes of Hourly_wage and Hours_per_week and the Salaried subclass has the additional attribute of Salary.
The subclass version of an attribute or behavior is said to override the version from the superclass when it is used in preference to the superclass version. In our example, the Make_weekly_paycheck behavior in the Hourly and Salaried subclasses are overrides, because weekly paychecks are calculated differently from each other.
The reusability feature of object-oriented languages means that classes created for one purpose can be used in a different OOP program if desired. In our example, the Employee class could be used in other programs, such as benefits calculations or work scheduling. Reusability can result in a large reduction in programming time in an organization.
