public 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"]
