Scott and Jeanne would like to thank numerous individuals for their contribution to this book. Thank you to Kathryn Duggan for guiding us through the process and making the book better in so 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. And thank you to Elena Felder for being our technical proofreader and finding the errors that we managed to sneak by Janeice. This book also wouldn’t be possible without many people at Wiley, including Kenyon Brown, Pete Gaughan, Kathleen Wisor, Kim Wimpsett, Nancy Carrasco, and so many others.
Jeanne would personally like to thank Chris Kreussling for knowing almost a decade ago that she would someday write a book. He was a great mentor for many years and definitely shaped her career. Jeanne would also like to thank Cathy Sung for all the support and coaching as Jeanne grew as a tech lead. Nicolai Parlog and Juan Moreno were helpful when looking for module information. 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 Java 8 books. Finally, Jeanne would like to thank all of the new programmers at CodeRanch.com and FIRST robotics teams FRC 694, FTC 310, and FTC 479 for the constant reminders of how new programmers think.
Scott could not have reached this point without his wife Patti and family, whose love and support makes this book possible. He would like to thank his twin daughters, Olivia and Sophia, and youngest daughter, Elysia, for their patience and understanding especially 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 fourth book. He doesn’t know how she puts up with him, but he’s glad she does and thrilled at the quality of books we produce. A big thanks to Matt Dalen, who has been a great friend, sounding board, and caring father to Olivia and Adeline. Joel McNary introduced Scott to CodeRanch.com and encouraged him to post regularly, a step that changed his life. Finally, Scott would like to thank his mother and retired teacher, Barbara Selikoff, for teaching him the value of education, and his father, Mark Selikoff, for instilling in him the benefits of working hard.
Last but not least, both Scott and Jeanne would like to give a big thank-you to the readers of our Java 8 certification books. Hearing from all of you who enjoyed the book and passed the exam is a great feeling. A special thank-you to Campbell Ritchie, who fielded an almost uncountable number of the questions on CodeRanch.com, helping readers understand the material better. We’d also like to thank those who pointed out errors and made suggestions for improvements in our practice exams book. As of August 2019, the top two were Juerg Bauman and Tamas Szekeres. We would also like to thank Noorul Hameed and Nurettin Armucutu for running a tight race for third-place errata reporter.
