No prior experience of Eclipse is assumed, and the book opens with an introduction that includes download and installation instructions for those who have don't even have the software yet. From there the book dives straight into showing the reader how to use and extend Eclipse to get the most out of it.
Part one of the book covers basic usage for the Java developer, and focuses on the various components of the JDT (Java Development Tooling). The first chapter looks at the different structural elements of the Eclipse work bench, including perspectives, views, editors and so on, and in particular how these are used in the JDT. This is followed by a chapter that runs through the process of developing a simple project, giving an overview of all of the essential components aside from the debugger. It includes writing code, customising the editor, writing JUnit test classes, running the code and so on. In effect it's a single chapter tutorial that touches on the core functionality used by Java programmers.
