Json

java.lang.Object
- de.qfs.lib.json.Json

```
public final class Json
extends java.lang.Object
```
This class serves as the entry point to the minimal-json API.
To parse a given JSON input, use the parse() methods like in this example:
```
 JsonObject object = Json.parse(string).asObject();
 
```
To create a JSON data structure to be serialized, use the methods value(), array(), and object(). For example, the following snippet will produce the JSON string {"foo": 23, "bar": true}:
```
 String string = Json.object().add("foo", 23).add("bar", true).toString();
 
```
To create a JSON array from a given Java array, you can use one of the array() methods with varargs parameters:
```
 String[] names = ...
 JsonArray array = Json.array(names);
 
```
To create a JSON array from any given Java object, you can use the value(object) method:
```
 Object object = ...
 JsonValue json = Json.value(object);
 
```
