27114-8 The first true design book inspired by Java(tm) Meet Charlie and Zoe, two users with highly individual User Interface needs. Follow them through the process of designing complex systems that use the power of Java to create unique online solutions. They'll introduce you to the brand-new design paradigm made possible by Java. Explore new concepts in development on the theoretical level, then put them to work with Charlie and Zoe to see their practical applications. Java-inspired design has some basic maxims that are carried out throughout this book. *Interfaces: Java's most significant aspect for designers is its freedom. Object connections and scenario interactions don't need to be hardwired to a single class of objects anymore-learn to use this freedom to gain flexibility, extensibility, and pluggability in your designs. *Composition: Basing your Java designs on composition, rather than inheritance, allows you to maximize this free structure. Java Design offers a five-fold checklist for determining which strategy is "the better one to apply." *Threads: Learn to manage multiple streams of program execution cleanly, efficiently, and safely.* Notification: Manage notification in ways that maximize the loose coupling supported by Java. Learn to identify the flaws in Java's own mechanism to keep your systems in sync. Java Design also includes a CD-ROM filled with cool code ready to use in your own apps, as well as a Strategies and Patterns Handbook with 177 strategies and 31 object-model patterns to guide your own app design.
