In Detail

GSON is a specialized Java-based library for handling JSON data, developed by Google. GSON demonstrates an efficient use of CPU time, memory efficiency, the library, and developer productivity. This book will help you implement GSON in your Java project.

Instant GSON is a practical, hands-on guide that provides you with all the implementation features of the GSON API through coded examples, which will help you take advantage of the real power that is behind the GSON API, and give you a good grounding to use it in your projects.

Instant GSON starts with an introduction to the JSON data format and GSON library. It will take you through the configuration steps required to set up a GSON-based Java project. You will learn about the top features of the GSON library, which includes handling generic type and nested class objects in Java, implementing versioning support, exclusion strategies, and pretty printing. At the end of the book you will find some useful references to articles, blogs, and active communities.

What you will learn from this book

• Convert Java objects to and from JSON
• Handle generic and null java objects
• Maintain different versions of serialized JSON
• Alter the name of fields when serializing
• Creating user defined annotation to remove fields while serializing
