Welcome to Java! At Deitel & Associates, we write college-level programming-language textbooks and professional books and work hard to keep our books up-to-date. Writing Java How to Program, Fifth Edition, (5/e for short), was a joy. This book and its support materials have everything instructors and students need for an informative, interesting, challenging and entertaining Java educational experience. As the book goes to publication, it is compliant with the latest version of Java—the Java 2 Platform, Standard Edition (J2SE), version 1.4.1—and with object-oriented design using the latest version of the UML (Unified Modeling Language) from the Object Management Group (OMG). We tuned the writing, the pedagogy, our coding style, the book's ancillary package and added a substantial treatment of developing database-driven Internet- and Web-based applications. We moved the Tour of the Book to the Preface. The tour will help instructors, students and professionals get a sense of the rich coverage the book provides of Java object-oriented programming, object-oriented design with the UML, and developing Internet- and Web-based applications. If you' are evaluating the book, please be sure to read the Tour of the Book, which starts on page xxxvi.

Whether you are an instructor, a student, an experienced professional or a novice programmer, this book has much to offer. Java is a world-class programming language for developing industrial-strength computer applications for devices ranging from cell phones and PDAs to the largest enterprise servers. We carefully audited the manuscript against the Java Language Specification, which defines Java. As a result, the programs you create by studying this text should work with any J2SE 1.4.1 compatible Java platform.

In this Preface, we overview Java How to Program, 5/e's comprehensive suite of educational materials that help instructors maximize their students' Java learning experience. We explain conventions we use, such as syntax coloring the code examples, "code washing" and highlighting important code segments to help focus students' attention on the key concepts introduced in each chapter. We overview the new features of Java How to Program, 5/e, including our enhanced treatment of object-oriented programming, Web-application development with servlets and JSP, the enhanced optional elevator-simulation object-oriented design (OOD) case study with the UML, the overview of design patterns and the extensive use of UML diagrams that have been upgraded to UML version 1.4 standards.

New Features in Java How to Program, Fifth Edition

This edition contains many new features and enhancements including:

Full-Color Presentation
This book is in full color to show programs and their outputs as they typically appear on a computer screen. We syntax color all the Java code, as do most Java integrated-development environments and code editors. This greatly improves code readability—an especially important goal, given that this book contains over 23,000 lines of code. Our syntax-coloring conventions are as follows:

• comments appear in green
• keywords appear in dark blue
• errors and JSP scriptlet delimiters appear in red
• constants and literal values appear in light blue
• all other code appears in black

Code Highlighting
We have added extensive code highlighting. In our code walkthroughs, we have eliminated most of the "redundant" code snippets that appeared inline in the text in earlier editions. We kept them in the earliest portion of the book as a pedagogic device to help novices. We want the reader to see all new code features in context, so from Chapter 4 forward, our code walkthroughs simply refer to the line numbers of the new code segments inside complete source programs. To make it easier for readers to spot the featured segments, we highlight them in bright yellow. This helps students review the material rapidly when preparing for exams or labs.

"Code Washing"
Code washing is our term for applying extensive comments, using meaningful identifiers, applying indentation and using vertical spacing to separate meaningful program units. This process results in programs that are much more readable and self-documenting. We have done extensive "code washing" of all the source code programs in the text, the lab manual, the ancillaries and the Cyber Classroom.

Tuned Treatment of Object-Oriented Programming in Chapters 9 and 10
This is one of the most significant improvements in this new edition. We performed a high-precision upgrade of Java How to Program, 4/e, Chapter 9 and split it into two chapters. The improvements make the material clearer and more accessible to students and professionals, especially those studying object-oriented programming for the first time.

Chapter 9, Object-Oriented Programming: Inheritance. The new Chapter 9 carefully walks the reader through a five-example sequence that demonstrates private data, protected data and software reuse via inheritance. We begin by demonstrating a class with private instance variables and public methods to manipulate that data. Next, we implement a second class with several additional capabilities. To do this, we duplicate much of the first example's code. In our third example, we begin our discussion of inheritance and software reuse—we use the class from the first example as a superclass and inherit its data and functionality into a new subclass. This example introduces the inheritance mechanism and demonstrates that a subclass cannot access its superclass's private members directly. This motivates our fourth example, in which we introduce protected data in the super-class and demonstrate that the subclass can indeed access the protected data inherited from the superclass. The last example in the sequence demonstrates proper software engineering by defining the superclass's data as private and using the superclass's public methods (that were inherited by the subclass) to manipulate the superclass's private data from the subclass. We follow the five-part introduction with a three-level class hierarchy that employs the software engineering techniques introduced earlier in the chapter. The chapter closes with a discussion of software engineering with inheritance.

Chapter 10, Object-Oriented Programming: Polymorphism. The new Chapter 10 builds on the inheritance concepts presented in Chapter 9 and focuses on the relationships among classes in a class hierarchy. Chapter 10 uses a three-example sequence to present the powerful processing capabilities that these relationships enable. We begin with an example that illustrates the "is-a" relationship between a subclass object and its superclass type. This relationship enables the subclass object to be treated as an object of its superclass. We show that we are able to assign a subclass object's reference to a superclass variable and invoke the superclass's methods on that object. This example uses polymorphism, which enables a program to process objects of classes related by a class hierarchy as objects of their superclass type. When a method is invoked via a superclass variable, the subclassspecific version of that method is invoked. In our second example, we demonstrate that the reverse is not true—a superclass object is not considered to be an object of its subclass type—and we show that compiler errors occur if a program attempts to manipulate a superclass object in this manner. Our third example demonstrates that the only methods which can be invoked through a superclass variable are those methods defined by the superclass type. The example shows that attempts to invoke subclass-only methods result in compilation errors. The chapter continues with a case study on polymorphism in which we process an array of variables that contain references to objects. All the objects referenced by the elements of the array have a common abstract superclass containing the set of methods common to every class in the hierarchy. We conclude with a case study that demonstrates how a program that processes objects polymorphically can still perform type-specific processing by determining the type of the object currently being processed.

Java New HO (NIO) APIs
Java's New I/O APIs are significant new additions to J2SE 1.4. We overview portions of these APIs in sections of three chapters. Section 11.8 demonstrates NIO's regular expression capabilities, which enable programs to search strings for character patterns. Section 17.13 introduces NIO's high-performance I/O classes that enable developers to take advantage of buffers, channels, charsets and more. This section also presents an example of using channels and buffers to write data to, and read data from, a file. Section 18.11 continues our discussion of the NIO APIs with an introduction to selectors and non-blocking I/O for implementing high-performance network servers. We then implement a distributed chat program that demonstrates these capabilities. Sections 11.8 and 17.13 also provide Web links for further study of the NIO APIs.

Database and Web-Applications Development with JDBC, Servlets and JSP
By popular demand, we have returned several topics to Java How to Program, Fifth Edition. Chapter 23, Java Database Connectivity with JDBC, demonstrates how to build data-driven applications with the JDBC™ API. Chapter 24, Servlets, and Chapter 25, JavaServer Pages™ (JSP), expand our treatment of Internet and Web programming topics and have everything readers need to begin developing their own Web-based applications that will run on the Internet! Readers will learn how to build so-called n-tier applications, in which the functionality provided by each tier can be distributed to separate computers across the Internet or executed on the same computer. In particular, we build a three-tier Web-based survey application and a three-tier Web-based guestbook application. Each application's information is stored in the application's data tier—in this book, a database implemented with IBM's Java-based Cloudscape database product (a trial version is on the CD that accompanies this book). The user enters requests and receives responses at each application's client tier, which is typically a computer running a Web browser such as Microsoft Internet Explorer or Netscape. Web browsers, of course, know how to communicate with Web sites throughout the Internet. The middle tier contains both a Web server and one or more application-specific servlets (in the case of our survey application) or JavaServer Pages (in the case of our guestbook application). We use Apache's Tomcat Web server as our application server for these examples. Tomcat, which is the reference implementation for the servlets and JavaServer Pages technologies, is included on the CD that accompanies this book and is available free for download from www.apache.org . Tomcat communicates with the client tier across the Internet using the HyperText Transfer Protocol (HTTP). We discuss the crucial role of the Web server in Web programming and provide many examples demonstrating interactions between a Web browser and a Web server.

Unified Modeling Language ™ (UML)
The Unified Modeling Language™ (UML) has become the preferred graphical modeling language for designing object-oriented systems. In Java How to Program, Fourth Edition, we used the UML in optional sections only, and we used conventional flowchart segments and inheritance diagrams to reinforce the explanations. We have fully converted the diagrams in the book to be UML 1.4 compliant. In particular, we upgraded all the figures in the UML/OOD Elevator Simulation case study; we converted all the flowcharts in Chapters 4 and 5 on Control Statements, to UML activity diagrams; and we converted all the inheritance diagrams in Chapters 9, 10, 12-13 and 15 to...
