package com.bethecoder.tutorials.json_java.tests;

import org.json.JSONException;
import org.json.JSONStringer;

public class ArrayStringer {

   @param args
   @throws JSONException 
  public static void main(String[] argsthrows JSONException {
    JSONStringer stringer = new JSONStringer();
    String jsonStr = stringer
        .array()    //Start JSON Array
              .object()      //Start JSON Object
                .key("age").value("2 years")    //Add key-value pairs  
              .endObject()    //End JSON Object
            .endArray()    //End JSON Array



It gives the following output,
[ {"name":"Sriram","age":"2 years","hobby":"painting"}, {"foo":"bar","hello":"world"} ]
