如何使用Java在此JSON对象中分离键和值? [英] How separate keys and values in this JSON object, using Java?

问题描述

我有类似JSON对象

{
 "projector":"no",
 "video_conference":"no",
 "polycom":"no",
 "lcd":"no",
 "digital_phone":"no",
 "speaker_phone":"no"
}

如何将键存储在一个数组中，并将值存储在单独的数组中?

How do I store the keys in one array and the values in a separate array?

推荐答案

您可以尝试一下.

 String s = " { "projector":"no", "video_conference":"no", "polycom":"no", "lcd":"no", "digital_phone":"no", "speaker_phone":"no" }";

        JSONObject jObject  = new JSONObject(s);
        JSONObject  menu = jObject.getJSONObject("projector");


        Iterator iter = menu.keys();
    String[] keyArr = new String();
    String[] valArr = new String();
    int count = 0;
        while(iter.hasNext()){
                 keyArr[count] = (String)iter.next();

             valArr[count] = menu.getString(key);
           count +=1;

        }
