Preface Preface to the Third Edition Java 8 is the new kid on the block.
Java 7 was a significant but incremental improvement over its predecessors. So much has changed since the previous edition of this book! APIs have come and gone across the entire tableau of Java: Preface to Previous Editions If you know a little Java, great.
If you know more Java, even better! This book is ideal for anyone who knows some Java and wants to learn more. I started programming in C in while working at the University of Toronto, and C served me quite well through the s and into the s. In , as the nascent language Oak was being renamed Java, I had the good fortune of being told about it by my colleague J.
Greg Davidson. A friend told me about WebRunner? It and Oak? Check out http: I downloaded HotJava and began to play with it. I wrote test and demo programs, sticking them a few at a time into a directory that I called javasrc to keep it separate from my C source because often the programs would have the same name. The javasrc directory kept growing. I wrote a Java course for Learning Tree,2 and the directory grew faster, reaching the point where it needed subdirectories.
Even then, it became increasingly difficult to find things, and it soon became evident that some kind of documentation was needed. In a sense, this book is the result of a high-speed collision between my javasrc directory andadocumentationframeworkestablishedforanothernewcomerlanguage.
The original model for such a book is, of course, the familiar kitchen cookbook. Transistor-transistor logic, or TTL, was the small-scale building block of electronic circuits at the time. Tom and Nathan worked out a xiv Preface www.
Well, not completely. The code is distributed with a Berkeley-style copyright, just to discourage wholesale reproduction. However, Chapter 1 covers some techniques that you might not know very well and that are necessary to understand some of the later material.
Feel free to skip around! Both the printed version of the book and the electronic copy are heavily cross- referenced. My main approach, then, is to concentrate on the Java APIs.
Like Perl, Java is a language that grows on you and with you. And, I confess, I use Java most of the time nowadays. Things I once did in C—except for device drivers and legacy systems—I now do in Java. Java is suited to a different range of tasks than Perl, however. As Tom and Nathan show, Perl excels at things like printing the 42nd line from a file.
Indeed, much of the API material added in Java 2 was aimed at this type of development. However, I will necessarily illustrate many techniques with shorter examples and even code fragments. Be assured that every fragment of code you see here except for some one- or two-liners has been compiled and run. Preface xv www. Some of the longer examples in this book are tools that I originally wrote to automate some mundane task or another.
For example, a tool called MkIndex in the javasrc repository reads the top-level directory of the place where I keep all my Java example source code and builds a browser-friendly index. For another example, the body of the first edition was partly composed in XML see Chapter 20 ; I used XML to type in and mark up the original text of some of the chapters of this book, and text was then converted to the publishing software format by the XmlForm program. This program also handled—by use of another program, GetMark—full and partial code insertions from the javasrc directory into the book manuscript.
XmlForm is discussed in Chapter I start off Chapter 1, Getting Started: Chapter 2, Interacting with the Environment moves from compiling and running your program to getting it to adapt to the surrounding countryside—the other programs that live in your computer. The next few chapters deal with basic APIs. Chapter 3, Strings and Things concentrates on one of the most basic but powerful data types in Java, showing you how to assemble, dissect, compare, and rearrange what you might otherwise think of as ordinary text.
The next two chapters cover data processing. As in most languages, arrays in Java are linear, indexed collections of similar-kind objects, as discussed in Chapter 7, Structuring Data with Java. Despite some syntactic resemblance to procedural languages such as C, Java is at heart an object-oriented programming OOP language.
Object and the important issue of design patterns. The next few chapters deal with aspects of traditional input and output. Chapter 12, Media: This chapter is a mix of the lower-level details such as drawing graphics and setting fonts and colors , and very high-level activities such as controlling a video clip or movie. Chapter 13, NetworkClientscoversthebasicsofnetworkprogrammingfromtheclientside,focusing on sockets.
For the third edition, Chapter 13, Network Clients has been refocused from applets and web clients to emphasize web service clients instead. Programs on the Net often need to generate or process electronic mail, so Chapter 17, Java and Electronic Mail covers this topic. Another textual form of storing and exchanging data is XML. Chapter 21, Packages and Packaging shows how to create packages of classes that work together.
Chapter 22, Threaded Java tells you how to write classes that appear to do more than one thing at a time and let you take advantage of powerful multiprocessor hardware. Sometimes you already have code written and working in another language that can do part of your work for you, or you want to use Java as part of a larger package.
The Afterword presents some closing thoughts and a link to my online summary of Java APIs that every Java developer should know about.
Finally, Appendix A gives the storied history of Java in a release-by-release timeline, so whatever version of Java you learned, you can jump in here and get up to date quickly. No two programmers or writers will agree on the best order for presenting all the Java topics. Platform Notes Java has gone through many major versions as discussed in Appendix A. This book is aimed at the Java 7 and 8 platforms.
I have compiled all the code in the javasrc xviii Preface www. The Java API consists of two parts: Programs that stick to this core API are reasonably assured of portability to any standard Java platform.
All standard extensions have package names beginning with javax. But note that not all packages named javax are extensions: A Java licensee such as Apple or IBM is not required to implement every standard extension, but if it does, the interface of the standard extension should be adhered to. Little code here depends on nonstandard extensions, other than code listed in the book itself. My own package, com.
Java Micro Edition Java ME is concerned with small devices such as handhelds, cell phones, fax machines, and the like. Speaking of cell phones and mobile devices, you probably know that Android uses Java as its language.
Java Books A lot of useful information is packed into this book. However, due to the breadth of topics, it is not possible to give book-length treatment to any one topic.
Because of this, Preface xix www. This is in keeping with my target audience: As the API continues to expand, so does the coverage.
You can also read them online through Safari, a paid subscription service. Though many books are mentioned at appropriate spots in the book, a few deserve special mention here. This is handy to keep beside your computer.
Head First Java offers a much more whimsical introduction to the language and is recommended for the less experienced developer. This book is out of print but can be found used and in libraries. Rethinking Best Practices offers useful insights in designing and implementing an Enterprise application. Figure P The remaining four volumes in the projected series are still not completed.
Although his examples are far from Java he invented a hypothetical assembly language for his examples , many of his discussions Preface xxi www. With apologies for algorithm decisions that are less relevant today given the massive changes in computing power now available.
This book continues the Bell Labs now part of Lucent tradition of excellence in software textbooks. In Recipe 3. Two important streams of methodology theories are currently in circulation. Conventions Used in This Book This book uses the following conventions. Programming Conventions I use the following terminology in this book. A program means any unit of code that can be run: An applet is a Java program for use in a browser.
An application is any other type of program. A desktop application a. The examples shown are in two varieties.
Those that begin with zero or more import statements, a javadoc comment, and a public class statement are complete examples. Those that begin with a declaration or executable statement, of course, are excerpts.
However, the full versions of these excerpts have been compiled and run, and the online source includes the full versions. Recipes are numbered by chapter and number, so, for example, Recipe 8. Typesetting Conventions The following typographic conventions are used in this book: Italic Used for commands, filenames, and example URLs.
It is also used to define new terms when they first appear in the text. Constant width bold Used for user input, such as commands that you type on the command line. Preface xxiii www.
This element signifies a tip or suggestion. This element signifies a general note. This icon indicates a warning or caution. Nobody should be using Java 5 or anything before it! If you are: Code Examples Many programs are accompanied by an example showing them in action, run from the command line.
Text before this prompt character can be ignored; it may be a pathname or a hostname, again depending on the system.
These will usually also show the full package name of the class because Java requires this when starting a program from the command line.

In preparing this edition, I have endeavored to correct these. My life has been touched many times by the flow of the fates bringing me into contact with the right person to show me the right thing at the right time.
Several people at the University of Toronto, but especially Geoffrey Collyer, taught me the features and benefits of the Unix operating system at a time when I was ready to learn it. Finally, thanks to the many Learning Tree instructors and students who showed me ways of improving my presentations. You can also visit their website. Years later, Mike Loukides encouraged me to keep trying to find a Java book idea that both he and I could work with. And he stuck by me when I kept falling behind the deadlines.
Mikealsoreadtheentiremanuscriptandmademanysensiblecomments,someofwhich brought flights of fancy down to earth. Jessamyn Read turned many faxed and emailed scratchings of dubious legibility into the quality illustrations you see in this book. My reviewer, Alex Stangl, read the manuscript and went far above the call of duty, making innumerable helpful suggestions, even finding typos that had been present in previous editions! Helpful suggestions on particular sections were made by Benjamin Preface xxvii www.
My thanks to all the translators for their efforts in making the book available to a wider audience. I thank you all! And again a thanks to all the readers who found errata and suggested improvements. Every new edition is better for the efforts of folks like you, who take the time and trouble to report that which needs reporting!
Second Edition I wish to express my heartfelt thanks to all who sent in both comments and criticisms of the book after the first English edition was in print. Gisbert did it all over again for the second edition and provided many code refactorings, which have made this a far better book than it would be otherwise. Going beyond the call of duty, Gisbert even contributed one recipe Recipe Thank you, Gisbert!
The second edition also benefited from comments by Jim Burgess, who read large parts of the book. My wife, Betty, and teenaged children each proofread several chapters as well.
