Formatting output

Some configuration parameters can be used to change the behavior of the JSON serialization/deserialization process. This is done by passing a JSON config object to the create method of the JsonBuilder class. The configuration object is used to hold some configuration metadata, which the jsonb object will be used during serialization/deserialization.

In the following example, we will create a JSON config object to be used within the jsonb object:

// Instantiate a custom JSON-B configuration object 
JsonbConfig config = new JsonbConfig(); 
 
 
// Instantiate a JSON-B object with our custom configuration 
Jsonb jsonb = JsonbBuilder.create(config); 

We have not performed any changes to the default configuration values of the jsonb configuration object. Now, let's enable one of the pretty features of jsonb, which is the formatting option.

The formatting option is used to format the output JSON, so that it's displayed with hierarchy and indentation to make it more readable by humans...
