Java Au Naturel

A computer science textbook by Dr. William C. Jones, Jr.
Fourth Edition   copyright May 26, 2004    www.javabook.org

Over 100 high school and college instructors across the U.S.A. and around the world are teaching from this textbook.

The first link in the following is the pdf file for the text material. The second link ("listings") is the source code for the program listings, in a form from which you can copy-and-paste (but not into a Word document, since it loses indents and line breaks; Notepad is okay, though).

DOWNLOADING: When viewing a file with a browser, you can click File/SaveAs... except that some browsers disable this for PDF files. Alternative: Put your mouse cursor on a link below (such as the one that says "Chapter 1") and right-click the mouse. This should give you a menu that allows you to choose "SaveLinkAs..." (in Netscape) or "SaveTargetAs..." (in IE). Click that option, then choose the folder on your hard drive where you want to save the PDF or HTM file. Frequent users should download the book in zipped form and unzip it to their own hard drive or a writable CD (roughly 4 MEGS, including these web pages).

Table of Contents and Preface to Student     10 pages
         Running programs in Chapter One requires  Turtle.java and its superclass  Turtlet.java
         Sample program for Chapter One:   ProgramOne.java
         Running the programs in Chapters Two and Three requires this file:    Vic.java
         If using BlueJ with these graphics classes, you will need to move their graphics window
         in front of the BlueJ window. With Turtles, it helps to make the first Turtle command
         a 5-second sleep command to give you time for this.

Dr. Bradley Kjell has very helpful webpages providing additional practice with Java, although they are not coordinated with this book. The object-oriented webpages can be covered much earlier than his numbering indicates.

Easy Buttons and Textfields and associated files
Learn to write applications using buttons and textfields during the early part of the course. This is quite accessible with Chapter Four, but independent of my textbook.

My course syllabi using this book can be linked to from this main page.
