Colophon
Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects.
The animals on the cover of Java Programming with Oracle SQLJ are eastern tiger swallowtail butterflies (Papilio glaucus). Butterflies belong to the order Lepidoptera, from the Greek lepid, "scale," and pteron, "wing," for the scale-like flattened bristles that cover the wings of the moths and butterflies that belong to this order.
Butterflies start life as an egg laid by an adult female butterfly. From this egg hatches a caterpillar, which eats large quantities of plant matter and sometimes insects as well. It grows rapidly, shedding its skin up to five times before reaching its full size. Once at this size, the caterpillar gets ready for its metamorphosis into a butterfly. Unlike moths, which spin themselves a cocoon, butterfly caterpillars spin a small disk of silk, attach it to a twig or other support, and grab onto it with their cremaster, a sort of claw at the end of their abdomen. They then shed their skin again; the pupa is underneath. Inside the pupa, their tissues and organs break down into a liquid and then reform as a butterfly; this stage can take anywhere from a week to several years. When they emerge, breaking open the pupa and crawling out, they pump blood into the veins of their wings to extend them. Once the wings have dried and hardened, the blood is withdrawn.
The colors in butterfly wings can be divided into two classes. One class is pigmentary colors, caused by actual pigments deposited in the scale-like bristles on the wings. The other class is structural colors; these often metallic or iridescent colors are caused by the diffraction of light as it is reflected off the scale structure of the wings.
Emily Quill was the production editor and copyeditor for Java Programming with Oracle SQLJ. Mary Brady and Nicole Arigo provided quality control. Pamela Murray wrote the index.
Emma Colby designed the cover of this book, based on a series design by Edie Freedman. The cover image is a 19th-century engraving from the Dover Pictorial Archive. Emma Colby produced the cover layout with QuarkXPress 4.1 using Adobe's ITC Garamond font.
David Futato designed the interior layout. Anne-Marie Vaduva and Neil Walls converted the files from Microsoft Word to FrameMaker 5.5.6 using tools created by Mike Sierra. The text font is Linotype Birka; the heading font is Adobe Myriad Condensed; and the code font is LucasFont's TheSans Mono Condensed. The illustrations that appear in the book were produced by Robert Romano and Jessamyn Read using Macromedia FreeHand 9 and Adobe Photoshop 6. The tip and warning icons were drawn by Christopher Bing.
