This is the digital version of the printed book (Copyright 2007).

Virtually all business, scientific, and engineering applications are heavily reliant on numeric data items. C++ and Java offer object-oriented programmers unique flexibility and control over the computations required within such applications.

However, most books on object-oriented programming gloss over such numeric data items, emphasizing instead one-dimensional containers or collections and components of the graphical user interface.

Object-Oriented Computation in C++ and Java
fills the gap left by such books.

Drawing on more than twenty years' experience as a software developer, tester, consultant, and professor, Conrad Weisert shows readers how to use numeric objects effectively.

Not limited to any language or methodology, the concepts and techniques discussed in this book are entirely independent of one's choice of design and coding methodology.

Practitioners of Extreme Programming, UML-driven design, agile methods, incremental development, and so on will all develop these same data classes.

Whether you are a seasoned professional or an advanced computer science student, this book can teach you techniques that will improve the quality of your programming and the efficiency of your applications. The exercises (and answers) presented in this book with teach you new ways to implement the computational power of C++, Java, and numeric data items.

Topics include

taxonomy of data types
developing and using object-oriented classes for numeric data
design patterns for commonly occurring numeric data types
families of interacting numeric data types
choosing efficient and flexible internal data representations
techniques for exploiting pattern reuse in C++
conventions for arithmetic operations in Java
numeric vectors and matrices
