In this book, we start off assuming that you know no programming language at all. We teach you Java one concept at a time and taking things real slow and easy. We believe that the best way to learn is to try and absorb just one concept at a time.
The book serves as a comprehensive guide, complete with a series of tutorials to help users better understand the many ways one can program in Java. It is meant to be both an introductory guide and a reference on Java and related technologies.

This e-book is an ongoing project to help Computer Science students who have had one or two semesters of Python learn the Java programming language. If you are not a part of that audience you may still find this a useful way to learn about Java.
