How to fetch data from a nested array?

I have to fetch the value from an array nested inside another array. I can fetch values from the first array but not able to fetch values from the second array.
I am able to read the values from the main array but I am unable to read the values from the array which is nested inside it.
JSONObject jsono = new JSONObject(res);
JSONArray jarray = jsono.getJSONArray("data");
for (int i = 0; i < jarray.length(); i++)
{
JSONObject object = jarray.getJSONObject(i);
JSONArray jarray1 = object.getJSONArray("comments_data");
for (int j = 0; j < jarray1.length(); j++)
{
JSONObject object1 = jarray1.getJSONObject(j);
String Namee = object1.getString("username");
String Ratingg = object1.getString("rating");
String Commentt = object1.getString("comment");
Comments comments1 = new Comments();
comments1.setUsername(Namee);
comments1.setRating(Ratingg);
comments1.setComments(Commentt);
comments1.setProfileimage(R.drawable.fav);
commentsList.add(comments1);
}
}
And this is my json.

Note carefully how you JSON is built.
First, you have to query for "data". You get JSON-Array. So you traverse it by the indices.
Hence, you query for the specific index in "data" (you can use a loop, of course).
For each iteration, you get a JSONObject, and in it you query for "comments_data".
String json = "{ \"status\": \"success\", \"msg\": \" Menu Details\", \"data\": [ { \"id\": \"1\", \"rest_id\": \"1\", \"menu_rate\": \"100\", \"collection_time\": \"2:22pm\", \"quantity_left\": \"3\", \"food_type\": \"veg\", ...
JSONObject object = new JSONObject(json);
JSONObject jarray1 = jarray_data.getJSONObject(0);
JSONArray comments = jarray1.getJSONArray("comments_data");

How to get a given below value from json data?

I need to get the images array data how to put into the adapter and not required adapter code? Only loop and how to add that's important for me
and then after second I can access option_value array.
First all images can be accessed then after a option_value array.

You should really look into How to parse JsonObject / JsonArray in android.
Please put your code of also what you have tried because people are here to help solve error/problem not to do coding.
Here is code from which you can Parse your json
JSONObject jsonObject = new JSONObject();
JSONObject dataObject = jsonObject.getJSONObject("data");
JSONArray imagesArray = dataObject.getJSONArray("images");
ArrayList<String> listOfImagesUrl = new ArrayList<>();
for(int i = 0; i < imagesArray.length(); i++)
{
listOfImagesUrl.add(imagesArray.getString(i)); // listOfImages
}
// code for option value
JSONArray optionsArray = dataObject.getJSONArray("options");
for(int i = 0; i < optionsArray.length(); i++)
{
JSONObject option = optionsArray.getJSONObject(i);
JSONArray optionsValueArray = option.getJSONArray("option_value");
for(int j = 0 ; j < optionsValueArray.length(); j++)
{
JSONObject optionValueObject = optionsValueArray.getJSONObject(j);
String image = optionValueObject.getString("image");
String price = optionValueObject.getString("price");
String price_prefix = optionValueObject.getString("price_prefix");
//same like this
}

My question is: how do I access the next question of "questions" when i click next for the next question since "58242", "58245", etc are all dynamic values?
the answer on this post was very helpfull but now i want to now how loop through the questions How to parse a dynamic JSON key in a Nested JSON result
it helped me get the currentdynamic value but does not give me the next question when i click on next
private View.OnClickListener nextListener = new View.OnClickListener() {
public void onClick(View v) {
setAnswer();
try {
if (quesIndex != searchResult.getJSONObject("questions").length() - 1) {
quesIndex++;
progress.setProgress(0);
progress.setMax(100);
} else {
Intent myIntent = new Intent(TestActivity.this, Assesment.class);
myIntent.putExtra("intVariableName", score);
startActivity(myIntent);
}
} catch (JSONException e) {
e.printStackTrace();
}
try {
if (quesIndex == searchResult.getJSONObject("questions").length() - 1) {
next.setText("Finish");
Intent myIntent = new Intent(TestActivity.this, Assesment.class);
myIntent.putExtra("intVariableName", score);
startActivity(myIntent);
// close this activity
finish();
}
} catch (JSONException e) {
e.printStackTrace();
}
showQuestion(quesIndex, review);
}
};
will appreciate the help thanks :)

Not sure what you problem is. Seems like the solution is in the link you gave above.
JSONObject questions = result.getJSONObject("questions");
Iterator keys = questions.keys();
//go through every question
while (keys.hasNext()) {
String currentDynamicKey = (String)keys.next();
JSONObject currentQuestion = questions.getJSONObject(currentDynamicKey);
}

JSONObject jsonResult = new JSONObject(jsonUser);
JSONArray data = jsonResult.getJSONArray("education");
if(data != null)
{
for(int i = 0 ; i < data.length() ; i++)
{
JSONObject c = data.getJSONObject(i);
String type = c.getString("type");
if(type.equalsIgnoreCase("college"))
{
JSONObject school = c.getJSONObject("school");

String name2 = school.getString("name");
JSONObject year = c.getJSONObject("year");
String id_y = school.getString("id");

}
}
}

Supposing that you've this json into a jsonObject that you retrieve as response, this is the way:
// Get jsonArray 'education' from main jsonObject
JSONArray jsonArrayEducation = jsonObject.getJSONArray("education");
JSONObject jsonSchool = jsonArrayEducation.getJSONObject("school");
Note that if you are interested only at the name, you can group the two lines above into
JSONObject jsonSchool = jsonObject.getJSONArray("education").getJSONObject("school");
// get school name
String schoolName = jsonSchool.getString("name");
