Dedication

With this edition of the book, I’d like to break from tradition and cheat my family and friends out of praise, because frankly it’s going to their heads. I dedicate this book to James Gosling, Mike Sheridan, Kim Polese, Bill Joy, and the others who launched the first version of this amazing programming language back in 1995. A language I was once surprised to see running on a web page is now running apps on millions of Android phones around the world—a testimonial to the visionary work you did at the late Sun Microsystems. Long may the purple reign!
