This tutorial is an introduction to using the BlueJ programming environment. BlueJ is a Java™ development environment specifically designed for teaching at an introductory level. It was designed and implemented by the BlueJ team at Deakin University, Melbourne, Australia, and the University of Kent at Canterbury, UK. More information about BlueJ is available at http://www.bluej.org.

1.2 Scope and audience This tutorial is aimed at people wanting to familiarize themselves with the capabilities of the environment. It does not explain design decisions underlying the construction of the environment or the research issues behind it. This tutorial is not intended to teach Java. Beginners of Java programming are advised to also study an introductory Java textbook or follow a Java course. This is not a comprehensive environment reference manual. Many details are left out – emphasis is on a brief and concise introduction rather than on complete coverage of features. For a more detailed reference, see The BlueJ Environment Reference Manual, available from the BlueJ web site (www.bluej.org). Every section starts with a one-line summary sentence. This allows users already familiar with parts of the system to decide whether they want to read or skip each particular section. Section 11 repeats just the summary lines as a quick reference.
