Gson Workbook

About the Book

We’ve published a book on Gson, which is designed to give you an in-depth learning experience. We specifically tailored it for every Java application and not just Retrofit developers.

The idea of this workbook is three-fold:

  • Give the readers of the Gson book a specific playground to practice the learned theory

  • Let experienced Gson users test their knowledge

  • Offer a way to learn Gson for people who don’t like reading technical books and rather experiment on their own.

We cover a lot of aspect of Gson in this workbook. We’ve roughly 40 tasks for you. If you wish, you can use our project framework. Automated unit tests will tell you if your implementation for that particular task was correct. Of course, every task comes with a sample solution.

The list below provides a comprehensive overview of covered topics within the book.

  • Introduction to JSON & JSON-Java mapping

  • Mapping of various Java data type

  • Dive into Gson’s configuration & customization options

  • Multiple tasks on Custom Serializer & Custom Deserializer
