JavaArray is an object that stores multiple variables of the same typestrong> e, which can hold primitive types and objects references , while JSONArray is an ordered sequence of values . Its outer text form is a string enclosed in square brackets with commas separating values, and its inner form is an object with get() and opt() methods, Used to access values added or replaced via index and element() methods. In the first step, we can create an Object[] array and pass this as a parameter to toJSON() >JSONSerializer class and typecast it to get a JSON array.
We can convert Object[] array to JSONArray in the example below
import net.sf.json.JSONArray; import net.sf.json.JSONSerializer; public class ConvertArrayToJSONArrayTest { public static void main(String[] args) { <strong>Object[]</strong> objArray = new <strong>Object[] </strong>{ "Array to JSON Array", new Integer(10), new Long(30), new Double(14.26), true, new char[] {'X', 'Y', 'Z'} }; <strong>JSONArray </strong>jsonArray = <strong>(JSONArray)JSONSerializer.toJSON</strong>(objArray); System.out.println(jsonArray.toString(3));<strong> //pretty print JSON</strong> } }
<strong>[ "Array to JSON Array", 10, 30, 14.26, true, [ "X", "Y", "Z" ] ]</strong>
