Introduction to Programming Using Java - Department of ...

Prefacexiof programming to cover more advanced topics. Chapter 8 is mostly about writing robust andcorrect programs, but it also has a section on parallel processing and threads. Chapters 9 and10 cover recursion and data structures, including the Java Collection Framework. Chapter 11 isabout files and networking. Finally, Chapter 12 returns to the topic of graphical user interfaceprogramming to cover some of Java’s more advanced capabilities.∗ ∗ ∗Major changes have been made in the fifth edition. Perhaps the most significant change isthe use of parameterized types in the chapter on generic programming. Parameterized types—Java’s version of templates—were the most eagerly anticipated new feature in Java 5.0.Other new features in Java 5.0 are also covered. Enumerated types are introduced, althoughthey are not covered in their full complexity. The “for-each” loop is covered and is usedextensively. Formatted output is also used extensively, and the Scanner class is covered (thoughnot until Chapter 11). Static import is covered briefly, as are variable arity methods.The non-standard TextIO class that I use for input in the first half of the book has beenrewritten to support formatted output. I have also added some file I/O capabilities to this classto make it possible to cover some examples that use files early in the book.Javadoc comments are covered for the first time in this edition. Almost all code exampleshave been revised to use Javadoc-style comments.The coverage of graphical user interface programming has been reorganized, much of it hasbeen rewritten, and new material has been added. In previous editions, I emphasized applets.Stand-alone GUI applications were covered at the end, almost as an afterthought. In the fifthedition, the emphasis on applets is gone, and almost all examples are presented as stand-aloneapplications. However, applet versions of each example are still presented on the web pages ofthe on-line version of the book. The chapter on advanced GUI programming has been movedto the end, and a significant amount of new material has been added, including coverage ofsome of the features of Graphics2D.Aside from the changes in content, the appearance of the book has been improved, especiallythe appearance of the PDF version. For the first time, the quality of the PDF approaches thatof conventional textbooks.∗ ∗ ∗The latest complete edition of Introduction to Programming using Java is always availableon line at http://math.hws.edu/javanotes/.
