JSON-javalib

This is a fast and simple JSON library for Java.

How to use

The important class is Toml.java. It contains public static methods for reading and writing JSON data. You can read data like this:

//import com.electronwill.json.Json
File file = new File("myFile.json");
FileReader reader = new FileReader(file);
Map<String, Object> jsonObject = Json.readObject(reader);

And write data like this:

//import com.electronwill.json.Json
File file = new File("myFile.json");
FileWriter writer = new FileWriter(file);
Map<String, Object> jsonObject = ...//put your data here
boolean humanFriendly = true;//true to indent and space the output, false to compact it
Json.write(jsonObject, writer, humanFriendly);

You can also use JsonReader and JsonWriter directly.

Data types

The JSON data is mapped to the following java types:

JSON	Java
Integer	int or long (it depends on the size)
Decimal	double
Boolean	boolean
String	String
Array	List<Object>
Object	Map<String, Object>
null	null

Java version

This library requires Java 7.
