JSON.simple

JSON.simple是一個簡單的Java類庫，用于解析和生成JSON文本。不依賴于其它類庫，性能高。

• Full compliance with JSON specification (RFC4627) and reliable (see compliance testing)

• Provides multiple functionalities such as encode, decode/parse and escape JSON text while keeping the library lightweight

• Flexible, simple and easy to use by reusing Map and List interfaces

• Supports streaming output of JSON text

• Stoppable SAX-like interface for streaming input of JSON text (learn more)

• Heap based parser

• High performance (see performance testing)

• No dependency on external libraries

• Both of the source code and the binary are JDK1.2 compatible

示例代碼：

System.out.println("=======decode=======");

  String s="[0,{\"1\":{\"2\":{\"3\":{\"4\":[5,{\"6\":7}]}}}}]";
  Object obj=JSONValue.parse(s);
  JSONArray array=(JSONArray)obj;
  System.out.println("======the 2nd element of array======");
  System.out.println(array.get(1));
  System.out.println();

  JSONObject obj2=(JSONObject)array.get(1);
  System.out.println("======field \"1\"==========");
  System.out.println(obj2.get("1"));   


  s="{}";
  obj=JSONValue.parse(s);
  System.out.println(obj);

  s="[5,]";
  obj=JSONValue.parse(s);
  System.out.println(obj);

  s="[5,,2]";
  obj=JSONValue.parse(s);
  System.out.println(obj);
