public class Json
extends java.lang.Object
```
Factory class for creating JSON processing objects. This class provides the most commonly used methods for creating these objects and their corresponding factories. The factory classes provide all the various ways to create these objects.
The methods in this class locate a provider instance using the method JsonProvider.provider(). This class uses the provider instance to create JSON processing objects.
The following example shows how to create a JSON parser to parse an empty array:
```
 
 StringReader reader = new StringReader("[]");
 JsonParser parser = Json.createParser(reader);
 
 
```
All the methods in this class are safe for use by multiple concurrent threads.

  - createParser
```
public static JsonParser createParser(java.io.Reader reader)
```
    Creates a JSON parser from a character stream.
    
    Parameters:
    reader - i/o reader from which JSON is to be read
    
    Returns:
    a JSON parser
  - createParser
```
public static JsonParser createParser(java.io.InputStream in)
```
    Creates a JSON parser from a byte stream. The character encoding of the stream is determined as specified in RFC 4627.

    Returns:
    a JSON parser
    
    Throws:
    
    JsonException - if encoding cannot be determined or i/o error (IOException would be cause of JsonException)
  - createGenerator
```
public static JsonGenerator createGenerator(java.io.Writer writer)
```
    Creates a JSON generator for writing JSON to a character stream.
    
    Parameters:
    writer - a i/o writer to which JSON is written
    
    Returns:
    a JSON generator
  - createGenerator
```
public static JsonGenerator createGenerator(java.io.OutputStream out)
```
    Creates a JSON generator for writing JSON to a byte stream.
    
    Parameters:
    out - i/o stream to which JSON is written
    
    Returns:
    a JSON generator
  - createParserFactory
```
public static JsonParserFactory createParserFactory(java.util.Map<java.lang.String,?> config)
```
    Creates a parser factory for creating JsonParser objects. The factory is configured with the specified map of provider specific configuration properties. Provider implementations should ignore any unsupported configuration properties specified in the map.
    
    Parameters:
    config - a map of provider specific properties to configure the JSON parsers. The map may be empty or null
    
    Returns:
    JSON parser factory
  - createGeneratorFactory
```
public static JsonGeneratorFactory createGeneratorFactory(java.util.Map<java.lang.String,?> config)
```
    Creates a generator factory for creating JsonGenerator objects. The factory is configured with the specified map of provider specific configuration properties. Provider implementations should ignore any unsupported configuration properties specified in the map.
    
    Parameters:
    config - a map of provider specific properties to configure the JSON generators. The map may be empty or null
    
    Returns:
    JSON generator factory
  - createWriter
```
public static JsonWriter createWriter(java.io.Writer writer)
```
    Creates a JSON writer to write a JSON object or array structure to the specified character stream.
    
    Parameters:
    writer - to which JSON object or array is written

    a JSON writer
  - createWriter
```
public static JsonWriter createWriter(java.io.OutputStream out)
```
