The code listed here is provided as a convenient way to access the listings in my "Bug Patterns" book in digital form. These listings are identical to those that appear in the book (modulo a few minor changes in indentation), with the listings for each chapter provided on a separate page. Although these pages are ".java" files, many of the listings are of code fragments, and many files contain more than one public class. As a result, many of the files will not (and are not intended to) compile directly.
