This book is written in the clear and concise style that has made Winston's C, C++, and Smalltalk books of the "On To" series so popular. 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. Using this book, readers learn Java quickly and effectively, and learn why Java is the language of choice for writing programs for the World Wide Web. On to Java 1.3 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. This book is designed for programmers familiar with other programming language who need or want to learn the Java language.
