Purpose:
We want to standardize the interface that remote locations use to
accept payments from our customers. All data is to be stored in a
file for nightly uploading to the central server.
Application title:
BillPayer
Algorithms:
The interface should accept data for the following eight fields.
•
Account Number
• Address
• City
• State
• Zip
•
Payment Amount
•
First Name
•
Last Name
The data needs to be verified for completeness before it is written.
Clicking the Close button should generate an “Are you sure?” type
of dialog box to guard against inadvertent closing before the end of
the day.
The name of the data file should include the system date to make
the name unique.
Notes:
Use the Swing Motif Look and Feel.
Make the interface appear the same size and in the same place each
time the program is run. The user should not be able to resize the
window.
