  1. APCS-A: Java Marine Biology Case Study Chapter 1 October 28, 2005

  2. Why a Case Study? • Gives you the opportunity to work through a large significant program (Not just a “toy” example) • Helps you think about issues of good program design • Helps you learn good code practice by looking at an expert’s code

  3. Getting Started - the code • //student/shared/US Courses -- copy the JavaMBS folder to your network drive

  4. Chapter 1: 9-17 Chapter 2: 18-51 Chapter 3: 52-62 Chapter 4: 63-78 Chapter 5: 79-107 Appendix A – Testable Classes and Concepts Appendix B – Source Code for Visible Classes Appendix C – Black Box Classes Appendix D – Environment Implementations Appendix E – Quick Reference for A test Appendix F – Quick Reference for AB test Appendix G – Index for Source Code And the “Book” • Student Manual to the Marine Biology Simulation Case Study (150 pages total)

  5. Object Diagrams • Cast of Characters • The Driver • The Simulation • Step (public method) • Fish: • act, location, id, color, direction (public methods) • move, nextLocation, emptyNeighbors (private methods)

  6. Study Skill Note • Some of this text is difficult to read • You might read a paragraph and not actually be paying attention and forget what you read • So you may have to re-read the same paragraph several times to understand and grasp what it is saying • Be active with the text while you read • Highlight • Make notes in the margin • Look at the diagrams as you try to figure out the explanation • Draw connections while you read

  7. Chapter 1 • Experimenting with the Marine Biology Simulation Program • Straight-forward, easy to read chapter • Do Analysis Questions and Exercise Sets as you read • Work on this in class today with a partner

  8. Role Play • We will be acting out the Marine Biology code Monday in class • Will help you better understand intercommunicating classes • Will help you become familiar with the classes of the case study • Homework: Read your Script • You will be speaking your lines, but not your “stage instructions” • Words in boldface represent requests that someone perform a task • Underlined phrases in angle brackets represent ideas that should be applied <your name> • Indentation matters
