## JSON Processing (JSON-P)
5

6
```java { .api }
7
public final class Json {
8
    public static JsonReader createReader(InputStream in);
9
    public static JsonReader createReader(Reader reader);
10
    public static JsonWriter createWriter(OutputStream out);
11
    public static JsonWriter createWriter(Writer writer);
12
    public static JsonObjectBuilder createObjectBuilder();
13
    public static JsonArrayBuilder createArrayBuilder();
14
    public static JsonParser createParser(InputStream in);
15
    public static JsonParser createParser(Reader reader);
16
    public static JsonGenerator createGenerator(OutputStream out);
17
    public static JsonGenerator createGenerator(Writer writer);
18
}
19

20
public interface JsonReader extends Closeable {
21
    JsonStructure read();
22
    JsonObject readObject();
23
    JsonArray readArray();
24
    void close();
25
}
26

27
public interface JsonWriter extends Closeable {
28
    void writeArray(JsonArray array);
29
    void writeObject(JsonObject object);
30
    void write(JsonStructure value);
31
    void close();
32
}
33
```
34

35
## JSON Binding (JSON-B)
36

37
```java { .api }
38
public interface Jsonb extends AutoCloseable {
39
    <T> String toJson(T object);
40
    <T> String toJson(T object, Type runtimeType);
41
    <T> void toJson(T object, OutputStream out);
42
    <T> void toJson(T object, Writer writer);
43
    <T> T fromJson(String str, Class<T> type);
44
    <T> T fromJson(String str, Type runtimeType);
45
    <T> T fromJson(Reader reader, Class<T> type);
46
    <T> T fromJson(Reader reader, Type runtimeType);
47
    <T> T fromJson(InputStream stream, Class<T> type);
48
    <T> T fromJson(InputStream stream, Type runtimeType);
49
    void close() throws Exception;
50
}
51

52
public final class JsonbBuilder {
53
    public static JsonbBuilder create();
54
    public JsonbBuilder withConfig(JsonbConfig config);
55
    public JsonbBuilder withProvider(JsonbProvider provider);
56
    public Jsonb build();
57
}
58
```

## Usage Example
61

62
```java
63
// JSON-P
64
JsonObject jsonObject = Json.createObjectBuilder()
65
    .add("name", "John Doe")
66
    .add("age", 30)
67
    .add("active", true)
68
    .build();
69

70
// JSON-B
71
Jsonb jsonb = JsonbBuilder.create();
72
User user = new User("John", "john@example.com");
73
String json = jsonb.toJson(user);
74
User deserializedUser = jsonb.fromJson(json, User.class);
75
```
