怎么在jsonarray取jsonobject？

Question

这是一组json数据，我已经取出data，现在想从records中取出rank，因为rank里的值不同，所以需要在取出后将其弄成一个map集合

{
        "code": 200,
        "data":{
        "records":[
        {
        "id":917834041955188736,
        "alertTime":"2021-12-07 17:44:48",
        "messageType":3,
        "snapId":101124,
        "rank":"1",
        "alertText":"低电压穿越保护",
        },
        {
        "id":917834020232888320,
        "alertTime":"2021-12-07 17:44:42",
        "messageType":1,
        "snapId":101124,
        "rank":"3",
        "alertText":"低电压穿越保护",
        },
        {
        "id":917833742737735680,
        "alertTime":"2021-12-07 17:43:36",
        "messageType":3,
        "snapId":101124,
        "rank":"2",
        "alertText":"低电压穿越保护",
        },
        {
        "id":917833717546745856,
        "alertTime":"2021-12-07 17:43:30",
        "messageType":1,
        "snapId":101124,
        "rank":"3",
        "alertText":"低电压穿越保护",
        }
        ]
     }
}

这是取出data的代码

public JSONObject page(String jsonData1) {
        JSONObject object = JSON.parseObject(jsonData1);
        JSONObject data = object.getJSONObject("data");

        return data;
    }

Answer 1

data.getJSONArray

  JSONArray recordList = data.getJSONArray("records");
    for (int i = 0; i < recordList.size(); i++) {
        JSONObject record = recordList.getJSONObject(i);
        String rank = record.getString("rank");
    }
