Q:

JSONObject Values into another JSONObject with Key Value Pair

I've a JSON like this 
{

      "result":
 {

    "issue_date": "xx-yy-zzzz",
    "father/husband": "TEST",
    "name": "ABC ",
    "blood_group": "",
    "dob": "xx-yy-zzzz",
    "validity": {
      "non-transport": "xx-yy-zzzz to xx-yy-zzzz",
      "transport": "xx-yy-zzzz to xx-yy-zzzz"
    },
    "cov_details": {
      "MCWG": "NA",
      "3WTR": "NA",
      "PSV BUS": "NA",
      "LMV": "NA",
      "INVCRG": "NA"
    },
    "address": "ABC"
  }
}

     JSONObject dlData = new JSONObject();
     JSONObject dlObj = new JSONObject();
     JSONObject dlcov = new JSONObject();
     JSONObject dlCovs = new JSONObject();
    dlCov = jsonObject.getJSONObject("result").getJSONObject("cov_details");

to access the data of cov_details,
i'm using this code block to store the details present within cov_details Object
         dlcov = jsonObject.getJSONObject("result").getJSONObject("cov_details");
        Iterator<String> x = dlcov.keys();
            while (x.hasNext()){
                String key1 = x.next();
                String value1 = dlcov.optString(key1);
                dlCovs.put("covabbrv",key1);
                dlCovs.put("dcIssuedt",value1);
                dlCovs.put("vecatg",key1);

            }

        dlData.put("dlCovs", dlCovs);

i am trying to store every values in dlCovs but it stores only last values in the object, is their anyway using which i can store all the value in dlCovs objet with it's Key value and iterate over it.Any help will be highly appreciable, thanks well in advance.

A:

Use JSONArray for covabbrv, dcIssuedt and vecatg
JSONArray covabbrv = new JSONArray();
JSONArray dcIssuedt = new JSONArray();
JSONArray vecatg = new JSONArray();
Iterator<String> x = dlcov.keys();
    while (x.hasNext()){
        String key1 = x.next();
        String value1 = dlcov.optString(key1);
        covabbrv.put(key1);
        dcIssuedt.put(value1);
        vecatg.put(key1);
    }
dlCovs.put("covabbrv",covabbrv);
dlCovs.put("dcIssuedt",dcIssuedt);
dlCovs.put("vecatg",vecatg);

Output would be somthing like:
{
    "covabbrv" : ["MCWG", "3WTR", "PSV BUS", "LMV", "INVCRG"],
    "dcIssuedt" : ["NA", "NA", "NA", "NA", "NA"],
    "vecatg" : ["MCWG", "3WTR", "PSV BUS", "LMV", "INVCRG"]
}
