CSSE 220 – Object-Oriented Software Development

Homework 21

Objectives

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

Tasks

1. Complete the assigned reading for the next session, according to the course schedule.

   • As you read, see if you can answer the self-check questions.
   • Bring your questions to class!
2. Complete the assessment exercise over this reading on ANGEL (under Lessons → Assignments).
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
     CSSE220 2008/22/10 8:05 9:50 F230
   

   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.
   
   You’ll commit your individual written work for this homework to the OODesign project inside Eclipse. Use the SVN Repositories view to check out this project.
   
   • 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 the index cards we provided you in class. The tactile interaction with the cards is part of the benefit.

     Bring your CRC Cards to class with you on Monday.

   • Use UMLet 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 UMLet, 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 UMLet file should appear.

   • You do not have to implement your design.

   This exercise is from Big Java, P12.7.

Turn-in Instructions

Turn in your individual written work by committing from Eclipse. Be sure that the UMLet file is checked in the commit dialog box so that it is added to the repository.

Bring your CRC Cards to class and turn them in to your instructor.
