I don't know if it's possible and would greatly appreciate any help
First I read the JSON store it into a variable:
JSONObject object = new JSONObject(JsonText);
System.out.println(object.length());
The System.out.println returns 3, so it knows we're talking about the 3 JSON Arrays.
And this how I try and get the Arrays
for (int i = 0; i < object.length(); i++){
JSONArray array = object.getJSONArray(HELP);
}
you can try this snippet
for (int i = 0; i < getArray.length(); i++) {
JSONObject objects = getArray.getJSONObject(i);
Iterator key = objects.keys();
while (key.hasNext()) {
String k = key.next().toString();
System.out.println("Key : " + k + ", value : "
+ objects.getString(k));
}
// System.out.println(objects.toString());
System.out.println("-----------");
}
You have to pass the value of i. But object.getJSONArray() accepts only string.So you can use like this.
JSONObject obj=new JSONObject(JsonText);
for(int i=0;i<obj.length();i++){
try {
JSONArray jsonArray=obj.getJSONArray(String.valueOf(i));
} catch (JSONException e) {
e.printStackTrace();
}
}

Hi All I am trying to parse a JSON String that contains a multidimensional array. I keep getting the following error in the logs -> W/System.err: org.json.JSONException: No value for nutrients and this error corresponds to the following line -> JSONArray jsonArray1 = jsonObject.getJSONArray("nutrients");
Can someone please help me with this issue. thanks in advance
The JSON String I am trying to parse ->
{
"results": [
{
"id": 654959,
"title": "Pasta With Tuna",
"image": "https://spoonacular.com/recipeImages/654959-312x231.jpg",
"imageType": "jpg",
"nutrition": {
"nutrients": [
{
"title": "Calories",
"amount": 420.823,
"unit": "kcal"
},
{
"title": "Protein",
"amount": 24.4751,
"unit": "g"
},
{
"title": "Fat",
"amount": 10.3277,
"unit": "g"
},
{
"title": "Carbohydrates",
"amount": 57.6915,
"unit": "g"
}
]
}
}
My Java code to parse it ->
try {
JSONObject jsonObject = new JSONObject(response);
JSONArray jsonArray = jsonObject.getJSONArray("results");
for (int i = 0; i < jsonArray.length(); i++) {
int id = jsonArray.getJSONObject(i).getInt("id");
String title = jsonArray.getJSONObject(i).getString("title");
String image = jsonArray.getJSONObject(i).getString("image");
Log.i("a", "" + title);
JSONArray jsonArray1 = jsonObject.getJSONArray("nutrients");
for(int e = 0; e < jsonArray1.length(); e++) {
JSONObject jsonObject1 = jsonArray1.getJSONObject(e);
double calories = jsonObject1.getDouble("amount");
Log.i("calories", "" + calories);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
Your JSON is invalid.
Here is a valid one
{
"results": [
{
"id": 654959,
"title": "Pasta With Tuna",
"image": "https://spoonacular.com/recipeImages/654959-312x231.jpg",
"imageType": "jpg",
"nutrition": {
"nutrients": [
{
"title": "Calories",
"amount": 420.823,
"unit": "kcal"
},
{
"title": "Protein",
"amount": 24.4751,
"unit": "g"
},
{
"title": "Fat",
"amount": 10.3277,
"unit": "g"
},
{
"title": "Carbohydrates",
"amount": 57.6915,
"unit": "g"
}
]
}
}
]
}
Then your Java code
try {
JSONObject jsonObject = new JSONObject(response);
JSONArray jsonArray = jsonObject.getJSONArray("results");
JSONObject resultsObject=jsonArray.getJSONObject(0);
int id = resultsObject.getInt("id");
String title = resultsObject.getString("title");
String image =resultsObject.getString("image");
Log.i("a", "" + title);
JSONObject nutrition = resultsObject.getJSONObject("nutrition");
JSONArray nutrients = nutrition.getJSONArray("nutrients");
for(int e = 0; e < nutrients.length(); e++) {
JSONObject jsonObject1 = nutrients.getJSONObject(e);
double calories = jsonObject1.getDouble("amount");
Log.i("calories", "" + calories);
}
} catch (JSONException e) {
e.printStackTrace();
}
Hope Helpful!
So I am incredibly new to Java and am needing help parsing a JSON response. I already have the method in which I am using to do so, but need help figuring out what exactly I am doing wrong.
I am using an API to retrieve recipes from a site. I am trying to get a list of recipes ("hits" in this case I assume?) that I can then show to the user.
Obviously I need the recipe name ("label" in this case) and other information. Can anyone help me?
Here is the response api response I am getting:

This is currently the method I am using to parse the JSON object:
public void onResponse(Call call, Response response) throws IOException {
if (response.isSuccessful()) {
final String myResponse = response.body().string();
getActivity().runOnUiThread(new Runnable() {
private Object Date;
#Override
public void run() {
String jsonData = myResponse;
query_result.setText(myResponse);
Log.d("response5", myResponse);
//JSONObject jsonData1 = new JSONObject(myResponse);
JSONObject Jobject = null;
try {
Jobject = new JSONObject(jsonData);
Log.d("jobject", Jobject.toString());
} catch (JSONException e) {
e.printStackTrace();
}
JSONArray Jarray = null;
try {
Jarray = Jobject.getJSONArray("hits");
} catch (JSONException e) {
e.printStackTrace();
}
for (int i = 0; i < Jarray.length(); i++) {
JSONObject object;
try {
object = Jarray.getJSONObject(i);
try {
JSONArray Recipe = object.getJSONArray("recipe");
}catch (JSONException e){
e.printStackTrace();
}
for (int j = 0; j < Jarray.length(); j++){
JSONObject object2 = null;
try {
object2 = Jarray.getJSONObject(j);
String Name = object2.getString("label");
String Photo = object2.getString("image");
Log.d("rec_query", " " + Photo);
}catch (JSONException e){
e.printStackTrace();
Log.d("response6:", e.toString());
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
});
}
}
});
return null;
}
}
NOTE THE {} {} are just different recipes...it wouldnt fit the whole response
At the moment, when I try to print my variables in the Log, I am getting a message that says the variable is empty (the variable that i used to store the different recipes/"hits".
Your response seems incomplete, it's not in the correct JSON format，Provide the right format and I'll try to help you
String s = "{\n" +
" \"a1\":\"1\",\n" +
" \"b2\":[\n" +
" {\n" +
" \"b21\":\"vb21\"\n" +
" },\n" +
" {\n" +
" \"b22\":\"vb22\"\n" +
" }\n" +
" ]\n" +
"}";
JSONObject object = JSON.parseObject(s);
String vb21 = object.getJSONArray("b2").getJSONObject(0).getString("b21");
like this,and neep to import com.alibaba.fastjson
But i dont`t know if you can use fastjson
I have multi Array key value string
For Example:
{
filters=[
{
eventConfig={
success=1.0,
bgColor=#27AE60,
successText=Yes
},
prid=9.0,
name=abc,
prqt=1.0,
price=199.89
},
{
eventConfig={
success=1.0,
bgColor=#27AE60,
successText=Yes
},
name=abc,
prid=10.0,
price=99.89,
prqt=1.0
},
{
eventConfig={
success=0.0,
bgColor=#C0392B,
successText=No
},
name=internet,
prid=11.0,
price=299.89,
prqt=1.0
},
{
eventConfig={
success=0.0,
bgColor=#C0392B,
successText=No
},
name=intermission,
prid=11.0,
price=299.89,
prqt=1.0
}
]
}
I'm trying to convert into json string but getting error while converting
i need output as
{
"filters": [
{
"eventConfig": {
"success": 1,
"bgColor": "#27AE60",
"successText": "Yes"
},
"prid": 9,
"name": "abc",
"prqt": 1,
"price": 199.89
},
{
"eventConfig": {
"success": 1,
"bgColor": "#27AE60",
"successText": "Yes"
},
"name": "abc",
"prid": 10,
"price": 99.89,
"prqt": 1
},
{
"eventConfig": {
"success": 0,
"bgColor": "#C0392B",
"successText": "No"
},
"name": "internet",
"prid": 11,
"price": 299.89,
"prqt": 1
},
{
"eventConfig": {
"success": 0,
"bgColor": "#C0392B",
"successText": "No"
},
"name": "intermission",
"prid": 11,
"price": 299.89,
"prqt": 1
}
]
}
Please use the following code snippet to Parse this response.
try {
JSONObject jsonObject = new JSONObject(response);
JSONArray filtersArray = jsonObject.getJSONArray("filters");
for (int i = 0; i < filtersArray.length(); i++) {
//Parsing eventConfig object
JSONObject eventConfigObject = filtersArray.getJSONObject(i).getJSONObject("eventConfig");
int success = eventConfigObject.getInt("success");
String bgColor = eventConfigObject.getString("bgColor");
String successText = eventConfigObject.getString("successText");
//Parsing other objects
int prid = filtersArray.getJSONObject(i).getInt("prid");
String name = filtersArray.getJSONObject(i).getString("name");
int prqt = filtersArray.getJSONObject(i).getInt("prqt");
int price = filtersArray.getJSONObject(i).getInt("price");
}
} catch (Exception e) {
e.printStackTrace();
}
Happy Coding!! Thanks..!
I have the below following type of json structure which is coming from url.
[{
"id": 1,
"name": "TV",
"fromcenter": {
"car": "60 Mins",
"bus": "20 Mins"
},
"location": {
"latitude": -33.7181,
"longitude": 10.3160
}
}, {
"id": 2,
"name": "Fridge",
"fromcenter": {
"car": "30 Mins"
},
"location": {
"latitude": -33.8433,
"longitude": 11.2411
}
}, {
"id": 3,
"name": "Mixie",
"fromcenter": {
"car": "20 Mins",
"bus": "40 Mins"
},
"location": {
"latitude": -3.8910,
"longitude": 11.27777
}
}]
I am able to parse everything except the "bus" because the bus is not available in id 2. So I am getting error as value "bus" not found. JSONException.
Let me know how to solve this? Below is what I tried.
try {
JSONArray array = new JSONArray(response);
goodModelArrayList = new ArrayList<>();
for (int i = 0; i < array.length(); i++) {
JSONObject e = array.getJSONObject(i);
spinnerModel = new MyTransport();
fromcenter = new Fromcenter();
location = new Location();
for (int j = 0; j < e.length(); j++) {
JSONObject object = e.getJSONObject("location");
latitude = object.getString("latitude");
longitude = object.getString("longitude");
}
for (int k = 0; k < e.length(); k++) {
JSONObject object = e.getJSONObject("fromcenter");
car = object.getString("car");
//bus = object.getString("bus"); //I am not able to get the bus. It throws JSONException error.
}
spinnerModel.setId(String.valueOf(e.getString("id")));
spinnerModel.setName(e.getString("name"));
spinnerModel.setFromcenter(car);
//spinnerModel.setBus(bus); //I am not able to store the datas.
spinnerModel.setLocation(latitude);
spinnerModel.setLocations(longitude);
goodModelArrayList.add(spinnerModel);
}
} catch (Exception e) {
e.printStackTrace();
}
you can interrogate if the object has the property before reading it
if (object.has("bus")) {
bus = object.getString("bus");
}
Straight forward one word.
Use optString instead of getString
optString eliminates this issue. Bus is not present in 2nd item.
So use
String bus= object.optString("bus");

In can't get String value in third Arraylist "list":[ because is same name with Second ArrayList "list":[.
But when I Toast Second ArrayList I see Second,third Arraylist but I can't get String third value and show nothing in Log or my listView or Toast String Value
how can I access Packname?
you have no Packname in your first array, please revise this
for (int j = 0; j < jsonArraylist.length(); j++) {
JSONObject objectlist = jsonArraylist.getJSONObject(j);
if(objectlist.has("Packname")){
String Packname= objectlist.getString("Packname");
Log.i("Log", "SHOW Packname " + Packname);
listmain.add(new ListViewMain(Packname));
}
}
adapter.notifyDataSetChanged();
please try this
