将JsonObject数组转换为整数

Question

I am getting the following response from my server:

{"SubjectName":["Irish","Maths","English","Science","Religion","Geography"],
"SubjectID":[1,2,3,4,5,6]}

What I need to do is try separate the response into two separate arrays SubjectName and SubjectID.

Here is what I have:

 try {
            jsonArray = jsonObject.getJSONArray("SubjectName");
        } catch (JSONException e) {
            e.printStackTrace();
        }
        SubjectName = new String[jsonArray.length()];
        for (int i = 0; i < jsonArray.length(); i++)
        {
            try {
                SubjectName[i] = jsonArray.getString(i);
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }

        try
        {
            jsonArray = jsonObject.getJSONArray("SUBJECTID");
            Log.v("Worked", "SubjectID is in ");

        } catch (JSONException e)
        {
            Log.v("failed","Not able to retrieve data");
            e.printStackTrace();
        }
        SubjectID = new int[jsonArray.length()];
        for (int i = 0; i < jsonArray.length(); i++)
        {

            try {
                SubjectID[i] = jsonArray.getInt(i);
            } catch (JSONException e)
            {
                e.printStackTrace();


            }
        }

The String seems to convert no problem and I can get the SubjectName but the SubjectID part seems to fail and I have no idea why. I've checked and I can't seem to find anywhere that shows me how to parse an int from the jsonaray.

You are using wrong node name.

Replace

jsonArray = jsonObject.getJSONArray("SUBJECTID");

with

jsonArray = jsonObject.getJSONArray("SubjectID");
