如何使用Java中的JSONlib API将集合转换为JSON数组？
import java.util.*; import net.sf.json.JSONArray; import net.sf.json.JSONSerializer; public class ConvertCollectionToJsonArrayTest { public static void main(String[] args) { List strList = Arrays.asList("India", "Australia", "England", "South Africa"); JSONArray jsonArray = (JSONArray)JSONSerializer.toJSON(strList); System.out.println(jsonArray.toString(3)); //pretty print JSON List
输出
[ "India", "Australia", "England", "South Africa" ] [ "List Data", 50, 99, 50.65, true, [ "X", "Y", "Z" ] ]登录后复制
