Acknowledgments
Scott and Jeanne would like to thank numerous individuals for their contributions to this book. Thank you to Kezia Endsley and Archana Pragash for guiding us through the process and making the book better in many ways. Thank you to Janeice DelVecchio for being our technical editor as we wrote this book. Janeice pointed out many subtle errors in addition to the big ones. Thank you to Elena Felder for being our technical proofreader and finding the errors that we managed to sneak by Janeice. And a special thank you to our copy editor Tiffany Taylor, for finding subtle errors that everyone (including us!) missed. This book also wouldn't be possible without many people at Wiley, including Kenyon Brown, Pete Gaughan, Christine O'Connor, and many others.
Scott could not have reached this point without his wife, Patti, and family, whose love and support make this book possible. He would like to thank his twin daughters, Olivia and Sophia, and youngest daughter, Elysia, for their patience and understanding and bringing him a cup of cold brew coffee when it was “time for Daddy to work in his office!” Scott would like to extend his gratitude to his wonderfully patient co-author, Jeanne, on this, their eighth book. He doesn't know how she puts up with him, but he's glad she does and is thrilled at the quality of books we produce. Finally, Scott would like to thank his mother, Barbara Selikoff (a retired teacher), for teaching him the value of education, and his father, Mark Selikoff, for instilling in him the benefits of working hard.
Jeanne would personally like to thank everyone who kept her sane during the COVID pandemic, especially Dani, Elena, Janeice, Joslyn, Norm, Rodrigo, Scott, and Wendy, along with the NYJavaSIG leadership team. She would also like to thank the KCDC (Kansas City Development Conference) leadership team for holding the first in-person conference she attended where she could test book material on unsuspecting attendees. Scott was a great co-author, improving everything Jeanne wrote while writing his own chapters. A big thank you to everyone at CodeRanch.com who asked and responded to questions and comments about our books. Finally, Jeanne would like to thank all of the new programmers at CodeRanch.com and FIRST robotics teams FRC 694 and FTC 310/479/8365 for the constant reminders of how new programmers think.
Both Scott and Jeanne would like to give a big thank you to the readers of our books. Hearing from all of you who enjoyed the book and passed the exam is a great feeling. We'd also like to thank those who pointed out errors and made suggestions for improvements to the Java 17 book. As of January 2022, the top two were Tomasz Kasprzyk and Jos Roseboom.
