详细说明： My first encounter with the Java programming language was during a one-week Java training session in 1997. I did not get a chance to use Java in a project until 1999. I read two Java books and took a Java 2 Programmer certification examination. I did very well on the test, scoring 95 percent. The three questions that I missed on the test made me realize that the books I read did not adequately cover all of the details on all of the necessary Java topics. I made up my mind to write a book on the Java programming language. So, I f ormulated a plan to cover most of the topics that a Java developer needs understand to use the Java programming language effectively in a project, as well as to get a certification. I initially planned to cover all essential topics in Java in 700 to 800 pages. As I progressed, I realized that a book covering most of the Java topics in detail could not be written in 700 to 800 hundred pages. One chapter that covered data types, operators, and statements spanned 90 pages. I was then faced with the question, “Should I shorten the content of the book or include all the details that I think a Java developer needs?” I opted for including all the details in the book, rather than shortening the content to keep the number of pages low. It has never been my intent to make lots of money from this book. I was never in a hurry to finish this book because that rush could have compromised the quality and the coverage of its contents. In short, I wrote this book to help the Java community understand and use the Java programming language effectively, without having to read many books on the same subject. I wrote this book with the plan that it would be a comprehensive one-stop reference for everyone who wants to learn and grasp the intricacies of the Java programming language. One of my high school teachers used to tell us that if one wanted to understand a building, one must first understand the bricks, steel, and mortar that make up the building. The same logic applies to most of the things that we want to understand in our lives. It certainly applies to an understanding of the Java programming language. If you want to master the Java programming language, you must start by understanding its basic building blocks. I have used this approach throughout this book, endeavoring to build each topic by describing the basics first. In the book, you will rarely find a topic described without first learning its background. Wherever possible, I have tried to correlate the programming practices with activities in our daily life. Most books about the Java programming language either do not include any pictures at all or have only a few. I believe in the adage, “A picture is worth a thousand words.” To a reader, a picture makes a topic easier to understand and remember. I have included plenty of illustrations in this book to aid readers in understanding and visualizing the contents. Developers who have little or no programming experience can have difficulty putting things together to make a complete program. Keeping them in mind, the book contains over 290 complete Java programs that are ready to be compiled and run. I spent countless hours doing research for writing this book. My main sources of research were the Java Language Specification, white papers and articles on Java topics, and Java Specification Requests (JSRs). I also spent quite a bit of time reading the Java source code to learn more about some of the Java topics. Sometimes it took a few months to research a topic before I could write the first sentence on it. It was always fun to play with Java programs, sometimes for hours, to add them to the book. ...展开收缩
