In this example, the clearFields() method is coded at the end of the BillPayer
class, although the placement of this method could be anywhere in the program.

Testing the BillPayer Program

The next step is to test the BillPayer program using the three records in
Table 8-12. It is good practice to attempt to enter one of the records several
times, leaving one of the text boxes blank each time until all the text boxes have
been tested.

Table 8-12 Sample Data for the BillPayer Program

The following steps test the BillPayer program by entering the data in
Table 8-12.
