How do I open a BlueJ project?

BlueJ projects, like standard Java packages, are directories containing the files included in the project. After starting BlueJ, use the Project – Open... menu command to select and open a project. Some example projects are included with the standard BlueJ distribution in the examples directory.

What is the BlueJ programming environment?

This tutorial is an introduction to using the BlueJ programming environment. BlueJ is 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.

Can BlueJ create executable JAR files?

BlueJ can create executable jar files. Executable jar files can be executed on some systems by double-clicking the file (for example on Windows and MacOS X), or by issuing the command java -jar .jar (Unix or DOS prompt). We will try this with the example project hello. Open it (it is in the examples directory).

Can I run BlueJ from a zip file?

The download is a zip file, the contents of which must be extracted before running BlueJ. (Do not try to run BlueJ directly from within the zip file without extracting it – this does not work). The standalone version of BlueJ saves user preferences in the directory to which it is extracted.
