All Implemented Interfaces:

Iterable<JsonElement>
```
public final class JsonArray
extends JsonElement
implements Iterable<JsonElement>
```
A class representing an array type in Json. An array is a list of JsonElements each of which can be of a different type. This is an ordered list, meaning that the order in which elements are added is preserved.
