用Java取出“max”

{

"b": 7.85,

"curveName": "qx1",

"k": 0.41,

"max": 29.3,

"stdDataBo": [

{

"x": 18.6,

"y": 23.83

}

]

}

这是存在list中的元素，取出“max”的值

这个是字符串还是一个对象,没说清楚呢?

import com.alibaba.fastjson.JSONObject;
....

String s = "{\n" +
        "\"b\": 7.85,\n" +
        "\n" +
        "\"curveName\": \"qx1\",\n" +
        "\n" +
        "\"k\": 0.41,\n" +
        "\n" +
        "\"max\": 29.3,\n" +
        "\n" +
        "\"stdDataBo\": [\n" +
        "\n" +
        "{\n" +
        "\"x\": 18.6,\n" +
        "\n" +
        "\"y\": 23.83\n" +
        "\n" +
        "}\n" +
        "\n" +
        "]\n" +
        "\n" +
        "}";
JSONObject jsonObject = JSONObject.parseObject(s);
System.out.println(jsonObject.get("max"));
