Preface Why This Book? The goal of this book is to cover the essence of what you need to know to develop object-oriented software using Java and UML. When you are through with this book, you should understand object- oriented software development well enough to answer the following questions: ● What is object orientation? ● What is the UML? ● What is Object-Oriented Analysis and Design? ● How do you do OOAD? ● What are object-oriented development methodologies? ● How do you use Java to write truly object-oriented programs? ● What is Swing, and how can you use it to write object-oriented graphical user interfaces? ● What are design patterns? ● What is refactoring? ● What tools do you use to write object-oriented programs? ● What are some guidelines for writing good code? ● What do I need to read next to learn even more about object orientation? Who Is This Book For? This book is intended for programmers who know the basics of file:///C|/oobook/Preface.html (1 of 6) [13/03/2003 02:55:04 }Ç Why This Book? programming with Java, and now want to understand the fundamentals of object-oriented software development. If you're fairly new to programming, and have had a class or two in Java, you're probably starting to feel comfortable using Java. So now, you're ready to really reap the benefits of true object-orientated programming in Java, and this book will help you. If you're an experienced programmer who wants to move from using an old style procedural programming language to developing object- oriented systems in Java, this book is also for you. This book will get you well down the path to real object-oriented software development. You will likely be able to learn the most important aspects of Java from the examples included in this book if you have a Java manual available for quick reference. However, this book should not be the last one you read on object orientation, the UML, or Java. Instead, it should give you the essential understanding of objects so you can read more advanced and detailed books on the topic with greater purpose. Overview of Chapters Chapter 1 is a brief introduction to objects and the benefits of object- oriented software development. Chapter 2 covers the fundamental concepts of object orientation. Object orientation has many important concepts, and of course, its own vocabulary. It is very important for you to understand the main concepts, and to be familiar with the specialized vocabulary. Even if you already are familiar with some object-oriented concepts, you should review them in this chapter. Chapter 3 covers how to use Java to write object-oriented programs. It is not really a Java tutorial, but rather concentrates on using Java to file:///C|/oobook/Preface.html (2 of 6) [13/03/2003 02:55:04 }Ç Why This Book? implement object-oriented concepts. The first part of the chapter covers very basic Java concepts. However, the later parts of the chapter cover more advanced topics such as object lifetime, copies of objects, and other concepts that are very important when working with classes and objects. Chapter 4 covers Object-Oriented Analysis and Design (OOAD). Rather than focusing on any specific OOAD methodology, Chapter 4 covers the basic concepts that are important for any methodology. The first four chapters cover the essence of object orientation. Chapter 5 takes a look at Graphical User Interfaces (GUIs) and the Java Swing library using the object-oriented perspective developed in the previous chapters. This object-oriented introduction to Swing is a somewhat different approach than is typically found in Swing tutorials. Chapter 6 ties everything together with a case study of a small Java application. The fundamental OOAD concepts covered in Chapter 4 are used to design the application, and the Java and Swing concepts covered in Chapter 3 and 5 are used for the implementation. The remainder of the book is less comprehensive in its treatment. The goal is to give you a good overview of the practical aspects of object- oriented programming. Chapter 7 introduces Design Patterns, a recent development that uses previously developed software design patterns to help make designing new software easier. Chapter 8 covers Refactoring, which is a disciplined object-oriented approach to revising and enhancing existing software. Chapter 9 gives brief overviews of some of the current software development methodologies for both large and small-scale object-oriented software projects. Chapter 10 covers some of the current software tools available for developing object-oriented software. Finally, Chapter 11 gives some of my personal guidelines for developing better software. file:///C|/oobook/Preface.html (3 of 6) [13/03/2003 02:55:04 }Ç Why This Book?

For example, you probably understand how encapsulation and implementation-hiding can increase the cohesion of classes. Languages like C# and Visual Basic are excellent for creating so-called coarsely grained types because they expose simple features for grouping and hiding both code and data. You can use cohesive types to raise the abstraction level across a system, which allows for loose coupling to occur. Systems that enjoy loose cou- pling at the top level are much easier to maintain because each subsystem isn’t as dependent on the others as they could be in a poor design. Those benefits are realized at the lower levels, too, typically through lowered complexity and greater reusability of classes. In figure 1.1, which of the two systems depicted would likely be easier to modify? Without knowing what the gray circles represent, most developers would pick the diagram on the right as the better one.
