Java Design: Building Better Apps and Applets (Yourdon Press computing series) (Paperback)

In this completely updated book, internationally-respected object oriented development experts Peter Coad and Mark Mayfield bring discipline to Java development, showing how to design Java client/server apps for maximum efficiency and reliability. They review object models, scenario views, multithreading, concurrency, exceptions, and more, presenting leading-edge design techniques that are proven to work. This new edition features UML 1.1 notation throughout; six powerful new strategies for designing with interfaces; important new coverage of swing classes, design models for Enterprise Beans, inner classes, packages, Infobus architecture and much more. The CD-ROM contains the breakthrough TOGETHER/J Whiteboard Edition, a completely free, Java-based, full UML, platform-independent visual modeler for enterprise-wide software development. For any professional software developer interested in client/server programming with Java.
