JSON is a lightweight, text-based and language independent data exchange Format. JSON can represent two structured types, such as object and array. An object is an unordered collection of key/value pairs, and an array is an ordered sequence of values.
We can use the JSONArray.toJSONString() method to convert the list into a JSON array, which is a static JSONArray method , which converts the list to JSON text , and the result is a JSON array.
Syntaxpublic static java.lang.String toJSONString(java.util.List list)
import java.util.*; import org.json.simple.*; public class ConvertListToJSONArrayTest { public static void main(String[] args) { List<String> list = new ArrayList<String>(); list.add("India"); list.add("Australia"); list.add("England"); list.add("South Africa"); list.add("West Indies"); list.add("Newzealand"); <strong> </strong> // this method converts a list to JSON Array String jsonStr = JSONArray.toJSONString(list); System.out.println(jsonStr); } }
["India","Australia","England","South Africa","West Indies","Newzealand"]
