From my web site http://javacook.darwinsys.com, just follow the Download link and you will be presented with three choices:
Download the entire source archive as a single large zip file
Download individual source files, indexed alphabetically as well as by chapter
Download the binary JAR file for the
com.darwinsys.util package needed to compile many
of the other programs
Most people will choose either #1 or #2, but anyone who wants to compile my code will need #3. See Section 1.5 for information on using these files.
Downloading the entire source archive (#1) gives a large zip file that contains all the files from the book (and more). This archive can be unpacked with jar (see Section 23.4), the free zip program from Info-ZIP, the commercial WinZip or PKZIP, or any compatible tool. The files are organized into subdirectories by topic; there is one for strings (Chapter 3), regular expressions (Chapter 4), numbers (Chapter 5) and so on. The archive also contains the index by name and index by chapter files from the download site, so you can easily find the files you need.
Downloading individual files is easy too: simply follow the links either by the file/subdirectory name or by chapter. Once you see the file you want in your browser, use File->Save or the equivalent, or just copy and paste it from the browser into an editor or IDE.
The files will be updated periodically, so if there are differences between what’s printed in the book and what you get, be glad, for you’ll have received the benefit of hindsight.
