现在，假设我想将响应对象的名称键的值更改为“churn”而不是 churnmodel。我已经尝试使用 put("name","churn") 这样做，但 name 键的值没有改变。我编写了以下 java 代码来更改特定键的值，但是当我将对象打印为字符串时，值仍然相同，但如果我打印 Jsonobject.get("name")，则返回正确的修改值（查看下面java代码中的注释以更好地理解）。请建议我如何使用我在下面附加的代码来完成任务。

      static httpUrirequest httpUrirequest = requestBuilder.get(uri).setheader(httpheaders.AUTHORIZATION,auth).build();
        public static voID main(String[] args) throws IOException,ParseException {
            httpResponse response = httpClIEnt.execute(httpUrirequest);
            System.out.println(response.getStatusline().getStatusCode());
            System.out.println(response.getEntity().getContentType());
            String str = "";
            ScAnner scAnner = new ScAnner(response.getEntity().getContent());
            while (scAnner.hasNext()) {
                str += scAnner.nextline();
            }
            scAnner.close();
            JsONParser parser = new JsONParser();
            JsONObject JsonObject = (JsONObject)parser.parse(str);
            JsonObject.put("name","churn");
            System.out.println(JsonObject.toString());// name value is not modifIEd properly to churn,prevIoUsly exisTing name i.e achurn is displayed as name
           System.out.println(JsonObject.get("name")) //prints churn
    }
