Java by Dissection
by Ira Pohl and Charlie McDowell
Addison-Wesley ISBN 0-201-61248-8
Enlisting the best-selling dissection method, this title teaches programming techniques and presents the Java language using a sound and structured method. Working code is dissected with explanations to the student on each newly encountered programming element and idiom found in the code. The presentation assumes no programming background; both CS1 students and experienced programmers unfamiliar with Java will find a carefully structured presentation of the Java language and its key programming concepts.
Features
- Assumes no previous programming experience
- Teaches the mainstream language features of Java 2, including AWT and threads, while remaining the appropriate length for a one-semester course on the subject
- Executable complete programs in every chapter are explained using the classic dissection method, a structured walk-through of the code
- Simplified Input package allows novice Java programmers to use the language early on without advanced knowledge of the language
- Common Programming Errors, end-of-chapter review questions, exercises, and summaries, as well as an Instructor's Manual with answers, make this an ideal text from which to learn and teach the material
Ira has also developed a general course outline for an introductory course in programming using this text.
Charlie McDowell has notes with slides for teaching from the Java by Dissection book.
The first three chapters of Java by Dissection are available for free in eMatter form as Chapter 1, Chapter 2, Chapter 3. You can buy this book online through Barnes and Noble.
The Java code examples in the book are available in several forms. The code is arranged in directories corresponding to the chapters of the book. To get to the unpacked version for any system, or to get individual program files, you can use the FTP directory (www.cse.ucsc.edu/~pohl/JBD/). Files are also available in zip form for Windows users and compressed tar form for UNIX users.
More information and the source code for the tio package is also available.

p4 (June Yoshiko Sison) Just after the table, change 'To execute step1, place the first number, 77, in the box pennies' to'...in the box price.'

p11 (Charlie McDowell) We refer to www.JavaByDissection.xyz as the website at which you can obtain the Draw applet. There is no such website and the name of the applet should be MiniCalcApplet. The MiniCalcApplet in the book is consistent with version 1.2 of the JDK and it can be found in the FTP directory for the book in chapter 8 at
An additional version, for those of you who have only JDK 1.1.x, is available at http://www.cse.ucsc.edu/~charlie/java/jbd/MiniCalcApplet.html.

(Correction submitted to AW July 2001)
p35 (James Sears) line -10 The output is confusing. It would be better to replace the colon with the word 'to' so that
System.out.println('type price (0:100):');
should beSystem.out.println('type price (0 to 100):');
p44 (Charlie McDowell) line -1, the -b +needs to be in front of the quare root expression as part of the numerator.

p82 - 83 (Vera Ta) Every occurence of println(...) that isn't System.out.println() needs to be changed to be System.out.println(). This occurs in the final else of the if-else example on page 82, in every case of the switch on page 82, and in the default case of the switch on page 83.

p190 (Charlie McDowell) 1st line second paragraph 'on page 31' should be 'on page 23'
(Correction submitted to AWL) (Corrected in eBook)
p194 (Charlie McDowell) The last paragraph return values are incorrect. The changes are shown in boldface. The paragraph should read:
These calls to method compareTo() will return a number less than 0 if str1 is lexicographically before the parameter. Essentially that means alphabetical order, but it also specifies an ordering for nonalphabetic characters. The calls will return a number greater than 0 if str1 is lexicographically after the parameter, and they will return 0 if the strings are equal.
The actual value is the difference of the first characters that didn't match. So in s1.compareTo(s2), if they differ at index diff then the return value is s1.charAt(diff) - s2.charAt(diff)
