F.2. Time Class Case Study

Our first example consists of two classes—Time1 (Fig. F.1) and Time1Test (Fig. F.2). Class Time1 represents the time of day. Class Time1Test is an application class in which the main method creates one object of class Time1 and invokes its methods. These classes must be declared in separate files because they’re both public classes. The output of this program appears in Fig. F.2.
