Instant GSON

Quick start – creating your first JSON in GSON

In this section, you will learn different ways to instantiate GSON and their significance, followed by a quick example code that shows the basic serialization of wrapper type Java objects.

Step 1 – instantiating GSON

To use the GSON library, an object of the com.google.gson.Gson class needs to be instantiated. A GSON object does not maintain any state; this characteristic helps in reusing the GSON object at multiple places.

The GSON library provides two ways for instantiating it:

• The default approach

In this approach, the GSON class object can be instantiated using the new keyword. This approach creates a gsonobject instance without any setting.
