Overview of this book

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.

So, what is GSON?

In this section, we will cover the JSON data exchange format and its significance, and give an introduction to the GSON library. Finally, we will look up the GSON library and its top features.

This chapter distills the theory of data exchange format from the main core. No previous knowledge about the subject is necessary, but I assume that you are familiar with the fundamentals of JavaScript.

The data exchange format is a very vital area of information technology. Data is read and consumed by many heterogeneous applications to form information. The heterogeneous nature means these applications take the input data in their proprietary format. This requires the input data to be preformatted before it is consumed by the main application, which adds an additional level of complexity to an application. To address this need, a common data exchange format is put in place for communication. This has led to the origin of many popular standard formats such as XML, YAML, and JSON.
