Java简单json不替换属性的值

Question

正如上面的标题所述，我试图将“name”的值替换为“abc”，但这似乎并没有覆盖它，因为它是相同的值使用 Simple Json 替换它后java代码。

这是我的java代码:

    String jsonString = 
    "{"
        + "\"data\":"
        + "["
            + "{"
                + "\"jazz\":\"black\","
                + "\"name\":\"white\","
                + "\"given\":\"red\","
                + "\"sam\":\"blue\","
                + "\"mail\":\"yellow\","
                + "\"member\":\"green\","
                + "\"department\":\"green\","
                + "\"title\":\"green\""
            + "}"
        + "]"
    + "}";
    JSONParser parser = new JSONParser();
    JSONObject jsonObj = (JSONObject) parser.parse(jsonString);
    JSONObject newJSON = new JSONObject();

    jsonObj.remove("name");
    jsonObj.put("name", "abc");

正如我所说，上面的代码似乎没有对 json 结构中已有的“name”属性执行任何操作。上面的输出如下所示:

{
    "data": [
        {
            "given": "red",
            "mail": "yellow",
            "jazz": "black",
            "name": "white",
            "member": "green",
            "department": "green",
            "title": "green",
            "sam": "blue"
        }
    ],
    "name": "abc"
}

输出应该是什么样的:

{
    "data": [
        {
            "given": "red",
            "mail": "yellow",
            "jazz": "black",
            "name": "abc",
            "member": "green",
            "department": "green",
            "title": "green",
            "sam": "blue"
        }
    ]
}

知道为什么不改变它吗？

这对我有用:

JSONArray jsonArray = (JSONArray)jsonObj.get("data");
    JSONObject jsonObject = ((JSONObject)(jsonArray).get(0));
    jsonObject.put("name", "abc");
    System.out.println(jsonObj.toJSONString());
