Introduction to Software Design with Java

Companion web site for the book "Introduction to Software Design with Java" by Martin P. Robillard, Springer, 2026. Material for the first edition and second edition is also available.

NEW! The third edition of the book was released on 5 January 2026. It improves the presentation of numerous topics and provides a thoroughly revised set of code fragments that incorporate the latest features of the language (such as records and the latests APIs) and follow a more effective style. The diagrams are now included as vector graphics and follow the UML standard more closely.

Interactive Code Samples

You can now view all the chapter code samples with additional on-demand documentation accessible directly from the code. Check out the CodeSample.info website.

Source Code

There are three source folders on this site:

• code-e1 The complete and commented version of the code samples for the first edition of the book;
• code-e2 The complete and commented version of the code samples for the second edition of the book.
• code-e3 The complete and commented version of the code samples for the third edition of the book.
• solutions-code The code file for selected exercises. The code files are referenced from the appropriate solutions pages.

Although you can browse the code on GitHub, the recommended way to peruse the code samples is to clone the repository. The repository includes the configurations files necessary to build the code automatically in Eclipse. However, because some code relies on the JavaFX library, you also need to:

1. Download the JavaFX SDK and unzip it to a desired location;
2. Create a new User Library under Eclipse -> Window -> Preferences -> Java -> Build Path -> User Libraries -> New
3. Name it JavaFX and include the jars under the lib folder from your unzipped JavaFX download location.

Practice Exercises

The exercises are meant to be completed in order, after studying each chapter. Exercises tagged with a star (:star:) are challenging and those tagged with a magnifying glass (:mag:) are based on the exploration of the sample applications.
