This text provides an accessible and practical guide to the Java programming langauge for science and engineering students. Aimed specifically at the scientific programmer, the focus of this book is unique, and discussion of issues such as interface components is almost entirely omitted. The examples in the text perform the kind of calculations that will interest scientists and engineers.  The book covers two areas. It begins by providing a tutorial introduction to the Java programming language, and then moves on to a discussion of scientific applications. The applications chapters are all self-contained and rely on only the language in the tutorial.
