Parsing Json data. Nested Objects giving an error

Parsing Json data. Nested Objects giving an error - java

So i have this data as below and i am trying to parse the data, i can see a lot about parsing JSONArrays online however, not so much on objects within objects. I have had a go and am getting an error. Here is the Json response I am only trying to return the marked fields:
{
"geomagnetic-field-model-result": {
"model": "wmm",
"model_revision": "2020",
"date": {
"value": "2020-07-14"
},
"coordinates": {
"latitude": {
"units": "deg (north)",
"value": 0.0
},
"longitude": {
"units": "deg (east)",
"value": 0.0
},
"altitude": {
"units": "km",
"value": 0.00
}
},
"field-value": {
"total-intensity": {
"units": "nT",
"value": 123 //Return this*****************
},
"declination": {
"units": "deg (east)",
"value": -123 //Return this*****************
},
"inclination": {
"units": "deg (down)",
"value": 123 //Return this*****************
},
"north-intensity": {
"units": "nT",
"value": 123
},
"east-intensity": {
"units": "nT",
"value": -123
},
"vertical-intensity": {
"units": "nT",
"value": 123
},
"horizontal-intensity": {
"units": "nT",
"value": 123
}
},
"secular-variation": {
"total-intensity": {
"units": "nT/y",
"value": 123
},
"declination": {
"units": "arcmin/y (east)",
"value": 123
},
"inclination": {
"units": "arcmin/y (down)",
"value": 123
},
"north-intensity": {
"units": "nT/y",
"value": 123
},
"east-intensity": {
"units": "nT/y",
"value": 123
},
"vertical-intensity": {
"units": "nT/y",
"value": 123
},
"horizontal-intensity": {
"units": "nT/y",
"value": 123
}
}
}
}
My attempt at parsing currently looks like this:
public void onResponse(JSONObject response) {
try {
JSONObject jsonObject = response;
String totalIntensity = jsonObject.getJSONObject("field-value").getJSONObject("total-intensity").getString("value");
String declination = jsonObject.getJSONObject("field-value").getJSONObject("declination").getString("value");
String inclination = jsonObject.getJSONObject("field-value").getJSONObject("inclination").getString("value");
} catch (JSONException e) {
Log.d("geoData", "Error recorded");
e.printStackTrace();
}
}
Am i totally wrong? Hopefully this is very easy for someone to put me right.

I assume that the response you get in the method is the whole JSON object that you have posted here.
You have a few issues:
Your data is not String it is Double or Integer, so you should use getDouble for example.
You forgot about one additional node geomagnetic-field-model-result.
You don't need to assign internal JSONObject jsonObject you can just use response.
To get to the values you should:
public void onResponse(JSONObject response) {
try {
// JSONObject jsonObject = response; you don't need this
Double totalIntensity = response
.getJSONObject("geomagnetic-field-model-result")
.getJSONObject("field-value")
.getJSONObject("total-intensity")
.getDouble("value");
Double declination = response
.getJSONObject("geomagnetic-field-model-result")
.getJSONObject("field-value")
.getJSONObject("declination")
.getDouble("value");
Double inclination = response
.getJSONObject("geomagnetic-field-model-result")
.getJSONObject("field-value")
.getJSONObject("inclination")
.getDouble("value");
// use it somehow
} catch (JSONException e) {
Log.d("geoData", "Error recorded");
e.printStackTrace();
}
}

Create a Schema and use the return values, it's much easier to work with

So now along as the schema doesn't change this will return the values in the correct format

You can use Jackson like this:
import com.fasterxml.jackson.databind.ObjectMapper;
ObjectMapper mapper = new ObjectMapper();
JsonNode jsonNode = mapper.readTree(input);
System.out.println(jsonNode.get("geomagnetic-field-model-result").get("field-value").get("total-intensity").get("value"));

Expected BEGIN_ARRAY but was String at line 1 column 61 . $ customer.Data

Customer_Event is Arraylist
#SerializedName("Customer_Event")
#Expose
private List<CustomerEvent> customerEvent = null;

Gson Library expecting the Array first not the Object. there is nothing wrong in your code. but need to modify the JSON Structure here.
Try using this structure :
Note rootArray is starting point/ is used for your reference
rootArray[
// object
{
"Key": value,
"Key": value,
"Key": value
}
// array1
"Customer_Data":[
{
"Key": value,
"Key": value,
"Key": value
}
],
// array 2
"All_Event": [
{
"Key": value,
"Key": value,
"Key": value
}
]
]

Why i'm getting expected begin_array but was String

This is my json data
{
"Success": true,
"Message": "User Not Found",
"Customer_Data": "",
"Customer_Device": "",
"Customer_Event": "",

I tried multiple ways from StackOverflow but still not getting error
expected begin_array but was String

Firstly got Error from below field, this 3 field is String but you set ArrayList. But it will be String. Like below.
"Customer_Data": "",
"Customer_Device": "",
"Customer_Event": "",
#SerializedName("Customer_Data")
#Expose
private String customerData;
#SerializedName("Customer_Device")
#Expose
private String customerDevice;
#SerializedName("Customer_Event")
#Expose
private String customerEvent;
Also, Have no any event field. so need change from
#SerializedName("Event")
#Expose
private List<EventDetail> eventDetails;
To
#SerializedName("All_Event")
#Expose
private List<EventDetail> eventDetails;

Your problem is in your #SerializedName:
#SerializedName("Event")
#Expose
private List<EventDetail> eventDetails;
The tag SerializedName must have the name of the element of the json. Then you must changue it for:
#SerializedName("All_Event")
#Expose
private List<EventDetail> eventDetails;

How do I deserialize a nested JSON array using GSON?

Here's an example of my JSON:
{
"status": "ok",
"rowCount": 60,
"pageCount": 6,
"value": [{
"CustomerID": 1911,
"CustomerTypeID": 3,
...
}
]
}
My POJO:
#SerializedName("CustomerID")
public Integer CustomerID;
#SerializedName("CustomerTypeID")
public Integer CustomerTypeID;
I want to pull everything under value.
How do I do this using Google's GSON?
I've tried doing it as I would normally, but for, obvious reasons, it didn't work:
Type collectionType = new TypeToken<ArrayList<Customer>>() {}.getType();
return gson.fromJson(json, collectionType);

You can not skip root JSON object. The simplest solution in this case is - create root POJO:
class Response {
#SerializedName("value")
private List<Customer> customers;
// getters, setters
}
And you can use it as below:
return gson.fromJson(json, Response.class).getCustomers();

You don't need to worry writing your own POJO.
just visit http://www.jsonschema2pojo.org/
and paste here your JSON data, it'll automatically return you converted classes as below

Java JSON Parse literal string

I'm making Java Application which runs with C++ Server and want to receive a JSON Object from the server. Basiclly I'm sending LatLng(Latitude, Longtitude) to the server and it's returning me elements from the Google Maps API, but the problem is that the return elements have escape characters in them and I can't parse them with JSONObject.
#Override
protected void onPostExecute(string output) {
super.onPostExecute(output);
try {
JSONObject data = new JSONObject(output);
String test = data.getJSONObject("main_Points").getString("name");

And

try {

Gson g = new Gson();
Example example = g.fromJson(data.toString(), Example.class);
} catch(Exception ex) {
ex.printStackTrace();
}
}
You will get everything in Example object.
I hope it will help your problem!

How to iterate key-value pair in Retrofit

I am having trouble parsing the below JSON structure. Basically I have to read the values object as list but the server returns as a JsonObject and the value changes based on the totalPageCount. Is there any way I can read the values as List? Should I use reflections ? Currently I am using Retrofit with returns the model class.
Any help is really appreciated.
Thank you
{
"page" : 0,
"pageSize" : 10,
"totalPageCount" : 1,
"values" : {
"key1" : "value1",
"key2" : "value2",
"key3" : "value3",
"key4" : "value4",
}
}
Model class :
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Example {
#SerializedName("page")
#Expose
private Integer page;
#SerializedName("pageSize")
#Expose
private Integer pageSize;
#SerializedName("totalPageCount")
#Expose
private Integer totalPageCount;
#SerializedName("values")
#Expose
private Values values;
public Integer getPage() {
return page;
}
public void setPage(Integer page) {
this.page = page;
}
public Integer getPageSize() {
return pageSize;
}
public void setPageSize(Integer pageSize) {
this.pageSize = pageSize;
}
public Integer getTotalPageCount() {
return totalPageCount;
}
public void setTotalPageCount(Integer totalPageCount) {
this.totalPageCount = totalPageCount;
}
public Values getValues() {
return values;
}
public void setValues(Values values) {
this.values = values;
}
}
-----------------------------------com.example.Values.java-----------------------------------
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Values {
#SerializedName("key1")
#Expose
private String key1;
#SerializedName("key2")
#Expose
private String key2;
#SerializedName("key3")
#Expose
private String key3;
#SerializedName("key4")
#Expose
private String key4;
public String getKey1() {
return key1;
}
public void setKey1(String key1) {
this.key1 = key1;
}
public String getKey2() {
return key2;
}
public void setKey2(String key2) {
this.key2 = key2;
}
public String getKey3() {
return key3;
}
public void setKey3(String key3) {
this.key3 = key3;
}
public String getKey4() {
return key4;
}
public void setKey4(String key4) {
this.key4 = key4;
}
}

This will work
private Map<String,String> values;
