List of JSON items in Android Studio

Question

I have this json:

{
"sid": "BiQo7DA4lMoRkeGN8mdfBXackyBarCSSauQtNRRKOmcfo2Ah0XCjaI1yevEoxWa09TkTOYrwGixRMvBr15h1d2",
"submissions": [{
    "submission_id": "1104764"
}, {
    "submission_id": "1104765"
}]
}

How can I in AndroidStudio get a list of items by submission_id?(there is always 30 items in "submissions")

Thanks

I'm trying with this code but show exception.

for (int i = 0; i < jObject.length(); i++) {
                        JSONObject subm = jObject.getJSONObject("submissions");
                        JSONObject jObj = subm.getJSONObject(String.valueOf(i));
                        testdata = testdata + " " + jObject.getString("submission_id");
                        //
                    }

I basically want to get all the elements inside the "submissions"...

Try this one:

if (!jObject.isNull("submissions")) {
    JSONArray submissions = jObject.getJSONArray("submissions");

    for(int i = 0; i < submissions.length(); i++) {
        JSONObject submission = submissions.getJSONObject(i);
        String submissionId = submission.getString("submission_id");
    }
}
