User JSONParser which is faster one.

Below is sample. there can be a btter example if you google. Hope this helps.

JSONParser parser=new JSONParser();
System.out.println("=======decode=======");
String s="[0,{\"1\":{\"2\":{\"3\":{\"4\":[5,{\"6\":7}]}}}}]";  
Object obj=parser.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=parser.parse(s);  
System.out.println(obj);                  
s="[5,]";  
obj=parser.parse(s);  
System.out.println(obj);                  
s="[5,,2]";  
obj=parser.parse(s);  
System.out.println(obj);
