All Superinterfaces:

AutoCloseable, Closeable
```
public interface JsonWriter
extends Closeable
```
Writes a JSON object or array structure to an output source.
The class Json contains methods to create writers from output sources (OutputStream and Writer).
The following example demonstrates how write an empty JSON object:
```
 
 JsonWriter jsonWriter = Json.createWriter(...);
 jsonWriter.writeObject(Json.createObjectBuilder().build());
 jsonWriter.close();
 
 
```
The class JsonWriterFactory also contains methods to create JsonWriter instances. A factory instance can be used to create multiple writer instances with the same configuration. This the preferred way to create multiple instances. A sample usage is shown in the following example:
```
 
 JsonWriterFactory factory = Json.createWriterFactory(config);
 JsonWriter writer1 = factory.createWriter(...);
 JsonWriter writer2 = factory.createWriter(...);
 
 
```

    array - JSON array that is to be written to the output source
    
    Throws:
    
    JsonException - if the specified JSON object cannot be written due to i/o error (IOException would be cause of JsonException)
    
    IllegalStateException - if writeArray, writeObject, write or close method is already called
  - writeObject
```
void writeObject(JsonObject object)
```

    Parameters:
    
    object - JSON object that is to be written to the output source
    
    Throws:
    
    JsonException - if the specified JSON object cannot be written due to i/o error (IOException would be cause of JsonException)
    
    IllegalStateException - if writeArray, writeObject, write or close method is already called
  - write
```
void write(JsonStructure value)
```

  - close
```
void close()
```
    Closes this JSON writer and frees any resources associated with the writer. This method closes the underlying output source.
