Understanding Inheritance 143 System.out.println( Mailing a check to + name + + address); } public float computePay() { return (float) salary/52.0; } } public class Hourly { public String name; public String address; public int SSN; public int number; public float hourlyRate; public float hoursWorked public void mailCheck() { System.out.println( Mailing a check to + name + + address); } public float computePay() { return (float) hoursWorked * hourlyRate; } } The Salary and Hourly classes demonstrate the need for inheritance. Although Salary and Hourly employees are different types, they are not entirely different. In fact, the two types of employees have a lot in common, as seen by the repetition of fields and methods in these two classes. Using inheritance will improve this design considerably, so keep in mind that writing two separate classes for the two different types of employees is not yet a satisfactory solution. As you can see, the Salary and Hourly classes are repeating code. Salary and hourly employees are still employees, and there is a lot of information in common between the two. Inheritance can be used in this situation not only to avoid repeating code, but also to create a program design that allows for better maintenance and code changes later. When two or more classes are different but share similar features, take the common elements of the classes and put them in a parent class. The classes can extend this parent class, thereby inheriting all the features of the parent, yet the different features can remain in each child class.
