Intended to teach readers Java and object orientation, as well as presenting object oriented design and analysis, Java for Practitioners is written such that it is possible to dip into chapters as required. It introduces concepts by getting the reader to follow exercises, rather than by extensive discussion, and includes the new release 1.2 of Java. Practicals are included at the of each chapter, as well as the Java Self-Tester, designed to allow readers to determine whether they are ready to take the Sun Java Certification exam, and follows a similar format and style to the actual Online Certification Examination. In short, a thoroughly comprehensive guide.
