WELCOME TO the Seventh Edition of Introduction to Programming Using Java, a free, on-line textbook on introductory programming, which 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. It is certainly not meant to provide complete coverage of the Java language.

The seventh edition requires Java 7, with just a couple brief mentions of Java 8. Previous versions included Java applets on the web pages that make up this book, but the applets have been eliminated from this version. Earlier editions of the book are still available; see the preface for links.

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. The PDF that includes links might be the best way to read it on your computer. Links to the downloads 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 README file for information about how to compile and run the examples.

  • http://math.hws.edu/eck/cs124/downloads/javanotes7-exercise-solutions.zip — A zip archive containing source code for all the end-of-chapter exercises.

• PDF Downloads:
  • http://math.hws.edu/eck/cs124/downloads/javanotes7-linked.pdf — a PDF version with internal links for navigation and external links to source code files, exercise solutions, and other resources that are not included in the PDF. Recommended for on-screen reading. Size: 6.3 Megabytes; 755 pages.
  • http://math.hws.edu/eck/cs124/downloads/javanotes7.pdf — a PDF version without links, more suitable for printing. This PDF is in the format that is used for the printed version of the text, except that it also includes an appendix listing example programs and a glossary (since they would have exceeded the lulu.com page limit). Size: 5.9 Megabytes; 762 pages.
• E-book Downloads.
  • http://math.hws.edu/eck/cs124/downloads/javanotes7.mobi, for Kindle.

          These should be considered experimental. Depending on the particular ebook reader that you use, there can be problems with rendering of long lines in program code sample. You might find that lines that are too long to fit across your screen are incorrectly split into multiple lines, or that the part that extends beyond the right margin is simply dropped. On some readers, you might be able to scroll horizontally to see the hidden text. 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 Copies Available from Lulu.com:
  • Printed versions — 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 rather thick printed version at http://www.lulu.com/content/612392. It is also available in two parts as http://www.lulu.com/content/559884 and http://www.lulu.com/content/822314. Note that these printed books are the original Version 7, and they still contain errors that have been fixed in Version 7.0.3. See the on-line news page for a list of substantive errors.
