Chapter 1: Elegance in Object-Oriented Design and 
Implementation
Section 1.0 Introduction
Section 1.1 Why worry?
Section 1.2 Software Engineering
Section 1.3 Criteria for elegant software
Section 1.4 Roadmap 
This chapter lays the groundwork for the rest of the text. It motivates the study of object-
oriented design and gives examples of software failures that could possibly have been 
prevented if the software had been designed better. It includes the properties that 
software should have in order to be called "elegant". It finishes with a summary of the 
contents of the other chapters in the text.

Section 2.11 Summary
This chapter reviews the basics of object-oriented programming and the advantages that 
such programming can provide to the programmer and software designer for making the 
software more flexible, extendable, reusable, and scalable.
Chapter 3: Elegance and Implementation Inheritance
Section 3.0 Introduction
Section 3.1 Four perspectives on inheritance
	Code reuse perspective
 Is-a perspective
 Public interface perspective
 Polymorphism perspective
Section 3.2 Sufficiency of code reuse

Section 3.5 Has-a relationships and UML associations
Section 3.6 Sufficiency of code reuse, the is-a relationship, public interfaces, and 
polymorphism
Section 3.7 Costs of using implementation inheritance
Section 3.8 Example: Person, Woman, and Man
Section 3.9 Example: Drawing polygons
Section 3.10 Example: Sorting
Section 3.11 Subclassing arrays in Java
Section 3.12 Inheritance vs. referencing revisited
Section 3.13 Summary
This chapter expands on the material in the preceding chapter to discuss more thoroughly 
the role of inheritance in object-oriented software design, including its advantages and 
disadvantages, and to discuss alternatives to inheritance.
Chapter 4: Elegance and Methods
Section 4.0 Introduction
Section 4.1 Coding Styles and Naming Conventions
Section 4.2 Methods and decomposition
Section 4.3 Cohesive Methods
Section 4.4 Well-formed objects and class invariants
Section 4.5 Internal documentation
Section 4.6 External documentation
Section 4.7 Case Study: Overriding the equals method in Java 
Section 4.8 Case Study: Overriding the clone method in Java
Section 4.9 Refactoring
Section 4.10 Code Optimization
Section 4.11 Summary and Further Reading
This chapter looks at issues concerning low-level code, such as readability, modifiability, 
and reusability. In this chapter, we assume that the classes and their desired behaviors 
have already been mapped out and only the implementation of those behaviors remains to 
be done. 
Chapter 5: Elegance and Classes
Section 5.0 Introduction
Section 5.1 Starting out finding classes and their relationships
	Extract nouns and verbs
 Use Concepts from the application domain
	Use CRC cards
	Class protocols
	The big picture
Section 5.2 Maximizing Cohesion
Section 5.3 Separation of Responsibility
Section 5.4 Duplication avoidance
Section 5.5 Complete and consistent protocols
Section 5.6 Mutability vs. Immutability Revisited
Section 5.7 Designing for change
Section 5.8 Law of Demeter
Section 5.8 Summary and Further Reading
This chapter looks at object-oriented software development at a higher level. We discuss 
how to design classes to solve particular problems. That is, we discuss general principles 
to follow when deciding what classes to create, what their behavior will be, and with 
what other objects they will communicate.

Section 6.0 Introduction
Section 6.1 Naive representations of money
Section 6.2 A USMoney class
Section 6.3 Using subclasses of Money to represent different currencies

Section 6.10 Alternate Implementation with binary trees
Section 6.11 Summary
This chapter is a small case study. It introduces several implementations of money, each 
a refinement of the preceding one.
Chapter 7: Introduction to Design Patterns
Section 7.0 Introduction
Section 7.1 The Adapter pattern
Section 7.2 The Singleton pattern
Section 7.3 The Iterator pattern
Section 7.4 The Command Pattern
Section 7.5 Factories
Section 7.6 Summary
This chapter introduces the reader to the topic of design patterns. We present four simple 
patterns as samples. The discussion of each pattern includes examples from earlier 
chapters of the book where the pattern was used but not explicitly stated. The succeeding 
chapters in the text introduce more design patterns in the contexts of their case studies.
Chapter 8: Figure-Drawing Application Case Study
Section 8.0 Introduction
Section 8.1 The User interface
Section 8.2 The Observer pattern
Section 8.3 The Figure hierarchy
Section 8.4 The Model-View-Controller architecture
Section 8.5 The Prototype pattern

Section 8.7 The Composite pattern
Section 8.8 The Memento pattern
Section 8.9 Summary
This chapter gives a case study of a drawing application. We start with a very simple 
application and in each section we add enhancements to it, which provides us with a 
context in which to introduce more design patterns and to use the design principles 
discussed earlier in the text. The sections include the discussion of several alternative 
designs and implementations of the application and their advantages and disadvantages.
