Preface
"Live in fragments no longer, only connect."
—Edgar Morgan Foster
Welcome to Java and Java for Programmers! At Deitel & Associates, we write programming language professional
books and textbooks for Prentice Hall, deliver corporate training worldwide and develop Internet businesses. This book
was a joy to create. It reflects recent changes to the Java language and to the preferred ways of teaching and learning
programming.
Features
Here's some key features of Java for Programmers:
The book uses Java Standard Edition 6; we carefully audited the manuscript against the Java Language
Specification.
The book is object-oriented throughout and the treatment of OOP is clear and accessible.
The early classes and objects presentation features Time, Employee and GradeBook class case studies that weave
their way through multiple sections and chapters, gradually introducing deeper OO concepts.
The book contains a rich treatment of GUI and graphics.
We tuned our object-oriented presentation to use the latest version of the UML™ (Unified Modeling
Language™)—the UML™ 2—the industry-standard graphical language for modeling object-oriented systems.
We include an optional OOD/UML 2 automated teller machine (ATM) case study in Chapters 1–8 and 10. An
appendix contains the complete code implementation. Check out the back cover testimonials.
We include several substantial object-oriented web programming case studies.
Chapter 20, Accessing Databases with JDBC, includes JDBC 4 and uses the Java DB/Apache Derby and MySQL
database management systems. The chapter features a database-driven address book case study that
demonstrates prepared (pre-compiled) statements and JDBC 4's automatic driver discovery.
Chapter 21, JavaServer Faces™ Web Applications, and Chapter 22, Ajax-Enabled JavaServer™ Faces Web
Applications, introduce web application development with JavaServer Faces (JSF) technology and use it with the
Netbeans IDE to build web applications quickly and easily. Chapter 21 includes examples on building web
application GUIs, handling events, validating forms and session tracking. Chapter 22 discusses developing Ajax-
enabled web applications. The chapter features a database-driven multitier web address book application that
allows users to add contacts and search for contacts. The application uses Ajax-enabled JSF components to
suggest contact names while the user types a name to locate.
Chapter 23, JAX-WS Web Services, uses a tools-based approach to creating and consuming web services—a
signature Web 2.0 capability. Case studies include developing blackjack and airline reservation web services.
We use a tools-based approach for rapid web applications development; all the tools are available free for
download.
We discuss key software engineering community concepts, such as Web 2.0, Ajax, SOA, web services, open
source software, design patterns, refactoring, extreme programming, agile software development, rapid
prototyping and more.
Chapter 18, Multithreading, benefitted from the guidance of Brian Goetz and Joseph Bowbeer—co-authors of
Java Concurrency in Practice, Addison-Wesley, 2006.
We discuss the SwingWorker class for developing multithreaded user interfaces.
