This is a beginning course in computer science using Java. No experience with using Java is assumed. This online course with exercises will teach you quite a lot about Java. You should also get familiar with the programs and running them, as discussed in chapter 7. You will obtain a better grasp and understanding of Java by attempting to write programs on your own and also going through the suggested programming exercises for each chapter. This online course has been used successfully by beginning programmers and by experienced programmers who wanted to learn Java. Some people have used it as a review for Java certification.
This online course assumes you have the Java Software Development Kit (SDK) version 1.1 or later from Sun and a simple text editor such as NotePad. For help with setting up and running the Java SDK look at this page (Essentials of the Java Programming Language, Lesson 1: Compiling and Running A Simple Program), this page (Java 2 SDK Standard Edition Documentation), and also here. You can also use more sophisticated environments, as well. For more information please check the frequently asked questions.
Part 1: Hardware and Software
Part 1 consists of general computer science topics but does not say much about Java. Topics include a general discussion of hardware and software, the nature of analog and binary signals, machine language and high level languages, language translation and interpretation. Readers who already know these topics can skip to Part 2, where Java instruction begins.
