WELCOME TO Version 9.0 of Introduction to Programming Using Java, a free, on-line textbook for introductory programming that uses Java as the language of instruction. This book is directed mainly towards beginning programmers, although it might also be useful for experienced programmers who want to learn something about Java.

Version 9 covers Java 17. It updates the previous version mostly by moving definitively to Java 17 and by adding a new Swing edition. This edition of Version 9 uses JavaFX for GUI programming; an alternative edition that uses Swing instead of JavaFX is also available. Earlier versions of the book are also available; see the preface for links to older versions.

You can the download this web site for use on your own computer. PDF, e-book, and print versions of the textbook are also available. Links can be found at the bottom of this page.

Readers are strongly encouraged to try out the sample programs as they read the book! You can download the source code separately or as part of the web site using the links below. See the README file for information about how to compile and run the examples.

          These should be considered permanently experimental. The ebooks include answers to quizzes and exercises but do not include source code for sample programs; the sample programs can be downloaded separately, above.
• Print Version Available from Lulu.com:
  • Printed version — I have made this book available for purchase in printed versions from the print-on-demand publisher lulu.com. This is for convenience only, for those who would like to have a bound printout in a nice form. (Please do not feel obliged to buy the printed version; I do not make any money from it!) The entire book is available in a thick and somewhat unwieldy 772-page printed version: Introduction to Programming Using Java. It is also available in two parts: Chapters 1 through 7, and Chapters 8 through 13.
• Source Files for the Book
  • Complete Sources — The complete source files that are used to produce both the web site and PDF versions of this book are available for download, but will be useful only to a very limited audience. See the end of the preface for more information and a link.
