/**
* A builder for creating {@link JsonArray} models from scratch, and for
* modifying a existing {@code JsonArray}.
* <p>A {@code JsonArrayBuilder} can start with an empty or a non-empty
* JSON array model. This interface provides methods to add, insert, remove
* and replace values in the JSON array model.</p>
* <p>Methods in this class can be chained to perform multiple values to
* the array.</p>
*
* <p>The class {@link jakarta.json.Json} contains methods to create the builder
* object. The example code below shows how to build an empty {@code JsonArray}
* instance.
* <pre>
* <code>
* JsonArray array = Json.createArrayBuilder().build();
* </code>
* </pre>
*
* <p>The class {@link JsonBuilderFactory} also contains methods to create
* {@code JsonArrayBuilder} instances. A factory instance can be used to create
* multiple builder instances with the same configuration. This the preferred
* way to create multiple instances.
*
* The example code below shows how to build a {@code JsonArray} object
* that represents the following JSON array:
*
* <pre>
* <code>
* [
* { "type": "home", "number": "212 555-1234" },
* { "type": "fax", "number": "646 555-4567" }
* ]
* </code>
* </pre>
*
* <p>The following code creates the JSON array above:
*
* <pre>
* <code>
* JsonBuilderFactory factory = Json.createBuilderFactory(config);
* JsonArray value = factory.createArrayBuilder()
* .add(factory.createObjectBuilder()
* .add("type", "home")
* .add("number", "212 555-1234"))
* .add(factory.createObjectBuilder()
* .add("type", "fax")
* .add("number", "646 555-4567"))
* .build();
* </code>
* </pre>
*
* <p>This class does <em>not</em> allow <code>null</code> to be used as a
* value while building the JSON array
*
