net.sf.json - JSONArray.fromObject

package com.ikoo;import java.util.ArrayList;import java.util.HashMap;import net.sf.json.JSONArray;public class Test {    public static void main(String[] args) {        ArrayList<HashMap<String, String>> list = new ArrayList<>();        for (int i = 0; i < 3; i++) {            HashMap<String, String> map = new HashMap<>();            map.put("num", String.valueOf(i * 10));            list.add(map);        }        System.out.println(list);// [{num=0}, {num=10}, {num=20}]        JSONArray jsonArray = JSONArray.fromObject(list);        System.out.println(jsonArray);// [{"num":"0"},{"num":"10"},{"num":"20"}]        String data = "{\"success\":true,\"nums\":" + jsonArray.toString() + "}";        System.out.println(data);// {"success":true,"nums":[{"num":"0"},{"num":"10"},{"num":"20"}]}    }}

將 jsonArray 再自訂群組裝的 json

{  "success":true,  "nums":[    {      "num": "0"    },    {      "num": "10"    },    {      "num": "20"    }  ]}
