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.

Jeanne got her Bachelor of Arts degree in 2002 and her Master in Computer Information Technology degree in 2005. She enjoyed getting her Master's degree in an online program while working full time. This was before online education was cool! Jeanne is also a Distinguished Toastmaster and a Scrum Master. You can find out more about Jeanne at www.jeanneboyarsky.com or follow her on Twitter @JeanneBoyarsky.
Scott and Jeanne are both moderators on the CodeRanch.com forums and can be reached there for question and comments. They also co-author a technical blog called Down Home Country Coding at www.selikoff.net.
In addition to this book, Scott and Jeanne are authors of seven best-selling Java books:
OCA: Java 8 Programmer I Study Guide (Sybex, 2015)
OCP: Java 8 Programmer II Study Guide (Sybex, 2016)
OCA / OCP Java 8 Programmer Practice Tests (Sybex, 2017)
OCP Java 11 Programmer I Study Guide (Sybex, 2019)
OCP Java 11 Programmer II Study Guide (Sybex, 2020)
OCP Java 11 Developer Complete Study Guide (Sybex, 2020)
OCP Java 11 Practice Tests (Sybex, 2021)
They are currently in the process of writing an OCP Java 17 Developer Practice Tests book due out later this year.
About the Technical Editor
Janeice DelVecchio has been a professional software developer for 12 years and has had a lifelong love of programming and computers. Editing technical books is a fun task for her because she likes finding and fixing defects of all types. In her day job she uses a very broad range of skills with technologies including cloud computing, process automation, advanced unit testing, and devops. She also volunteers at CodeRanch.com, where she runs the Java class known as the Cattle Drive. She is an expert with the Java programming language. If you ask her which language is the best, she will tell you that languages are tools and to pick the one that fits your use case. The first language she learned was BASIC, and one day she hopes to learn gaming development. In her spare time, she enjoys cooking, solving puzzles, playing video games, and raising chickens. She loves eating sushi, drinking craft beer, and petting dogs – her guilty pleasure is 1980s pop music. She lives in Litchfield County, Connecticut.
About the Technical Proofreader
Elena Felder got into Java development back when the language lacked even generics, and she is delighted that the language, its tooling, and its community have continued growing and adapting to successfully keep up with the ever-changing world. She proofread one of Jeanne and Scott’s first Java 8 Certification Study Guide chapters for fun and ended up doing it professionally ever since.
