Das Buch ist eine Einfuhrung in die Programmiersprache Java. In den ersten Kapiteln werden die Grundlagen behandelt: Klassen, Objekte, Interfaces und Pakete. Weitere Kapitel befassen sich mit Benutzeroberflachen, der Ausnahmebehandlung, der Threadprogrammierung, mit Client/Server-Implementierung, Javas Sicherheitsmechanismen und dem Aufruf entfernter Methoden. Alle Sprachkonstrukte und die verwendeten Klassen der Java-Standardbibliothek werden an Beispielen verdeutlicht. An die einzelnen Kapitel schliesst sich eine Reihe von Ubungsaufgaben an. Die kompletten Beispielprogramme und Losungen zu den Ubungen befinden sich auf der beiliegenden CD-ROM.

In der 4. Auflage wurde die Behandlung des IO-Frameworks um das New IO API (NIO), das seit JDK 1.4 neben das streambasierte API tritt, erweitert. Einige Client/Server-Beispiele wurden auf NIO umgestellt. Bei der Ausnahmebehandlung wurde das neue Java-Sprachkonstrukt der Zusicherungen (assertions) erganzt."
