Code, Explanations and Solutions Companion

Companion to Object Oriented Development and Agile Practices

This section contains the official code companions, lab walkthroughs, and verified solutions for each chapter of Object Oriented Development and Agile Practices.

Companion Content Structure

Every chapter’s companion provides:

1. Executable Java Code Listings: Production-quality Java classes and suites conforming to the running Campus Equipment Lending System.
2. Step-by-Step Code Walkthroughs: Line-by-line analyses of design decisions, type safety, invariants, and exception handling.
3. Lab Solutions & Exercises: Model answers for both required core labs and optional team extensions.
4. Verification Records & Fault Experiments: Documented test suite outputs (mvn verify), mutation/fault analysis records, and reproducible compiler checks.
5. Delta Versions: Clear listings of new or modified files built on top of preceding chapter versions.

Select a chapter or appendix companion from the sidebar or table of contents to view its complete code listings and solutions.

📘 Note on Appendices: Code companions are provided for Appendices A, B, C, and F (which contain runnable listings, diagnostic code, and validation tools). Appendix D (Project Versions and Glossary) and Appendix E (Critical Reading and Project Evidence) are comprehensive non-code reference guides contained directly within the main textbook.
