1. Star UML and CRC Cards
Pepper

2. Goals
CRC
StarUML
Code Generation

3. Good Class Design Cohesive No unnecessary coupling
only one abstraction
No unnecessary coupling
No printing to a specific device such as screen scanner
Related data in the same class

4. Class UML Diagram Each class box: Relations
Name / state / behavior
Relations
Has a
Knows a
Uses a
Is a
Great Explanation matched to code

5. CRC cards One per noun / entity / object
Class: Noun is the class name on the top
Responsibility: List responsibilities on the left
Collaboration: List collaborating objects on the right
If a class is being used in a collaboration, its card will not show the collaboration – the user shows the collaboration

6. CRC Exercise 5 card draw List objects / entities
Make one card for each
Walk through the game
Draw a UML diagram
