This book provides a solid introduction to the technologies underlying Java (JDK 1.2) as well as the extensions of this language. To facilitate a deep understanding, it explains the paradigms of object-oriented programming and the reusability of software components. A particular focus of the book is to clarify the relationships between the various components. The authors demonstrate through examples how Java can be used and how different components must be combined to implement a complete application. Therefore, the book covers not only general aspects of the Java language (AWT, Networking and Security, Internationalization) but also Swing, JavaBeans, JDBC, RMI, Corba, and Servlets. The book comes with a CD-ROM that includes an HTML version of the text, applets, and the source files for all examples.
