CSSE 220 – Object-Oriented Software Development

Homework 20

Objectives

Practice with user stories, object-oriented design and implementation, GUIs, and basic data structures.

Tasks

1. There is no assigned reading for the next session.
2. You’ll commit your individual written work for this homework to the OODesign project inside Eclipse. Use the SVN Repository Exploring perspective to check out this project, then switch back to the Java perspective.
3. Written Assignment: Using the CRC Card technique we practiced in class, complete an object-oriented design (not implementation) for a program that implements an appointment calendar. An appointment includes the date, starting time, ending time, description, and location; for example,

     Dentist 2008/30/10 17:30 18:30 1060 W. Addison

   Your design must include a user interface to add appointments, remove canceled appointments, and print out a list of appointments for a particular day. Your design should include a class AppointmentCalendar that is not coupled with the Scanner or PrintStream classes.
   • Brainstorm a list of potential classes. You may work with classmates on the brainstorming. If you do that, you should each turn in separate lists and indicate with whom you worked. Turn in your list by adding a plain text file to the project in Eclipse. You can use File → New → Untitled Text File to add a new text file to an Eclipse project.

   • Use CRC Cards to determine the classes you will use, their responsibilities and collaborators. You must create the CRC Cards individually and on paper. The tactile interaction with the cards is part of the benefit.

     Scan your CRC cards and save the images to your Eclipse workspace → OODesign folder. (There is a scanner in F217 that you can use for this purpose. Instructions are taped to the table by the scanner. Contact Darryl Mouck, F205, if you have questions about the scanner.) Within Eclipse, right-click the OODesign project folder in the Package Explorer view, and choose Refresh. Your CRC Card images should appear.

   • Use Violet to draw a UML class diagram showing the relationships between your classes. You do not have to include details of the methods, though you may if that helps. You must create your UML class diagram individually.

     To commit your UML Class Diagram, you’ll also add it to your Eclipse project. In Violet, choose Save As to save the file to your Eclipse workspace → OODesign folder. Within Eclipse, right-click the OODesign project folder in the Package Explorer view, and choose Refresh. Your Violet file should appear.

   • You do not have to implement your design.

   This exercise is from Big Java, P12.7.

4. Team Assignment: Working with your team, complete the assigned milestone of the Vector Graphics project.

Turn-in Instructions

Turn in your individual written work by committing from Eclipse. Be sure that the Violet file and your CRC Card images are checked in the commit dialog box so that they are added to the repository.

See the Vector Graphics project description for team project deliverables.
