Introduction

Gson is a Java library that can be used to convert Java Objects into their JSON representation. Gson considers both of these as very important design goals.

Gson Features:

Provide simple toJson() and fromJson() methods to convert Java objects to JSON and vice-versa

Allow pre-existing unmodifiable objects to be converted to and from JSON

Extensive support of Java Generics

Support arbitrarily complex objects (with deep inheritance hierarchies and extensive use of generic types)
