This repository is Java adaptation of sample code for the book
Principles, Practices and Patterns of Domain-Driven Design.
The original code is written in C#.
Samples use various frameworks and technologies. These frameworks were replaced with the most close Java equivalents.
Samples in some chapters are complete applications. For such chapters, I added additional readmes.
I described replacements, problems, and screenshots of running apps.
Most technologes are replaced with equivalents that are popular in the Java world.

Besides replacement of technologies, there is some language "sugar" to keep code more aligned to the book examples.
