On to Java, Third Edition offers a clear and concise introduction to the Java programming language. In this third edition, the authors increase coverage of advanced material, explaining how to ensure good programming practice using interfaces, build complex systems using the model-view approach to system design, add sophistication to graphical interfaces with complex tables, define new layout managers for special situations, increase program flexibility using factories, package applications into JAR files, enable program interaction via remote method invocation and create network services using servlets. Written in the same style as the C, C++, and Smalltalk books of the On to series, this carefully designed tutorial is ideal for programmers who need to learn the Java language. To illuminate the key concepts of Java, the authors add various capabilities to a short, yet representative Java program, which demonstrates how Java is used for building both stand-alone programs and Web applets.
