如何在Java中将列表转换为JSON数组？

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);      // this method converts a list to JSON Array       String jsonStr = JSONArray.toJSONString(list);       System.out.println(jsonStr);    } }  输出结果  [India,Australia,England,South Africa,West Indies,Newzealand]
