This book has been designed as a tutorial. Not only does it explain the new stuff in plain English, it provides an introduction on each of the new technologies, making learning them fun. For instance, if you've never done Drag and drop swing before don't worry. There is a comprehensive introduction on this cool technology before a discussion of Java 6 DnD. If you're new to the Java Management Extensions (JMX) API, Fear not. This book provides a tutorial on JMX before detailing the new features in it.
