JSON-lib is a java library for serializing and de-serializing java beans, maps, arrays and collections in JSON format. Get the latest binaries from sourceforge http://json-lib.sourceforge.net/. This requires the libraries ( json-lib-2.4-jdk15.jar, xom-1.2.7.jar, ezmorph.jar commons-lang.jar, commons-collections.jar, commons-beanutils-1.7.jar and commons-logging-1.1.1.jar) to be in classpath. The following example shows using element method of JSON Array.

package com.bethecoder.tutorials.json_lib.tests;

import net.sf.json.JSONArray;

public class JsonArrayAddElement {

  /**
   @param args
   */
  public static void main(String[] args) {

    JSONArray jsonArray = new JSONArray()
            .element("one")
            .element(new Integer(2))
            .element(new Long(3))
            .element(new Double(4.00))
            .element(true)
            .element(new char [] { 'A''B''C' });
    
    System.out.println(jsonArray.toString(2))//pretty print with indent
  }

}
   

It gives the following output,
[
  "one",
  2,
  3,
  4,
  true,
    [
    "A",
    "B",
    "C"
  ]
]


                    Print
