Use the JSONObject
// Get some JSON from wherever
String json = getJSONFromServer();
// Parse the JSON response into an object
JSONObject object = new JSONObject(json);
// Get the results array
JSONArray users = object.getJSONArray("results");
for(int i = 0; i < users.length(); i++) {
// Each element in the results array is a JSONObject with a single
// property "user" which is a JSONObject that contains the user data
JSONObject user = users.getJSONObject(i).getJSONObject("user");
// Do something with the user
String firstName = user.getString("first_name");

How to write a REST API method for which consume json format for list of objects

I have written a method as following.
#POST
#Path("/add")
#Produces(MediaType.APPLICATION_JSON + ";charset=utf-8")
#Consumes(MediaType.APPLICATION_JSON + ";charset=utf-8")
public boolean createMeasurement(List<MeasurementBean> list ,#HeaderParam(AUTHORIZATION) String authString){
Gson gson = new Gson();
LoginSession loginSession=null;
try{
loginSession = LoginUtility.validateKey(authString);
ResultRO<List<HashMap<String, Object>>> resultRO = loginSession
.execute(new Callable<ResultRO<List<HashMap<String, Object>>>>() {
#Override
public ResultRO<List<HashMap<String, Object>>> call() throws Exception {
String key[] = idKey.split(":");
String type = key[0];
long testId = Long.parseLong("2");
return doGetCreateMeasurement(list ,2);
}
});
return gson.toJson(true);
}catch(Exception ex){
ex.printStackTrace();
}
return null;
}
I am not able to consume the list of objects from json format.

but when I am trying to POST request using postman it gives following error
WARNING: No message body reader has been found for request class MeasurementBeans, ContentType : application/json.
and also method is not executing.

You are accepting a List<MeasurementBean> in the createMeasurement() method and the JSON you have mentioned is an object.
{
"beans": []
//..
}
Just make it as an array by removing the starting {, "beans:" and ending }, i.e you just need to pass the array.

Sorting a JSON object in Android studios (java)

I've been searching for a while on how to sort a JSON object like this. It has a lot of attributes but I'm just trying to sort the objects into alphabetical order by "name":
I'm really new to java so you have any information to get started that'll be great!
//update:
So I figured out how to extract the attributes of each restaurant and now I'm trying to implement a comparator to sort the json objects but I'm confused on how to call the comparator and what arg to input
This is the comparator I'm using (got it from the internet)
public class AlphabeticalComparator implements Comparator<String> {
public int compare(String obj1, String obj2) {
if (obj1 == null) {
return -1;
}
if (obj2 == null) {
return 1;
}
if (obj1.equals( obj2 )) {
return 0;
}
return obj1.compareTo(obj2);
}
}
I'm also a little confused on how this sorts the objects since it will only return an integer. The json object im trying to sort is below
This is the JSON Object I get in response when I connect to the zomato API

Write a Comparator that orders a pair of JSON objects based on their respective name attributes. Then use that to sort your array of JSON objects; e.g. using Arrays.sort(objects, comparator).
Here is a (more general) example:
https://stackoverflow.com/a/45555429/139985
You can modify that code to replace the OffersOrder class with your JSON object type (or a custom class) and then implement the comparator to compare objects and return the appropriate value.

I'm only familiar with using Google's gson library which is a bit old. If there are better json parsers available I'm sure somebody can chime in.
You'd use it like this to extract the information:
String restaurantName;
JsonElement restaurantJSONElement;
JsonPrimitive restaurantJSONPrimitive;
JsonParser parser = new JsonParser();
// myJSONstring is the raw JSON data
JsonElement parentJSONElement = parser.parse(myJSONstring);
JsonObject parentJSONObject = parentJSONElement.getAsJsonObject();
JsonArray restaurantsJSONArray = (JsonArray) parentJSONObject.get("restaurants");
for(int i=0;i<restaurantsJSONArray.size();i++){
//get the element
restaurantJSONElement = ((JsonObject)restaurantsJSONArray.get(i)).get("restaurant");
//get the restaurant name
restaurantJSONPrimitive = ((JsonObject)restaurantJSONElement.getAsJsonObject()).getAsJsonPrimitive("name");
restaurantName = restaurantJSONPrimitive.getAsString();
}
You could extract all the members and do whatever you want with them, put them in custom object arrays and sort them by restaurantName as the comparitor

That's because your JSON is invalid... Paste your JSON codes here, https://codebeautify.org/jsonviewer , it will allow you to manipulate the formating, and take a better look into it...
I'm not an expert in Java but listing a nested array ( no matter, JSON or plain array ) can be done in two ways:
foreach ( $array as $item) {
foreach ( $item as $key => $data) {
echo $data;
}
}
for ( $i=0; $i < $array.lenght(); $i++ ) {
for ( $j=0; $j < $array.lenght-1; $j++) {
print_r $array[$i][$j];
}
}
Using foreach method is better if you don't know how long, or nested your array is...

Your json data is not well formatted ,try to print below one:
{
"a": [
{
"id": 1,
"user_id": 1,
"first_name": "John",
"last_name": "",
"b": [
{
"id": 1,
"customer_id": 1,
"created": "2017-10-10T07:29:45+00:00"
}
],
"c": [
{
"id": 1,
"customer_id": 1,
"created": "2017-10-10T07:29:45+00:00"
}
]
}],
"b":[{
"id": 1,
"user_id": 1,
"first_name": "John",
"last_name": "",
"b": [
{
"id": 1,
"customer_id": 1,
"created": "2017-10-10T07:29:45+00:00"
}
],
"c": [

How to access JSON element which is an array

I have the GSON library in my project, I need the ext_id. I am able to access "images" using the JSON.get("images"), however I am unable to get into the images array. Can someone please help me with this.
{

You can try this one.
public void parse(String jsonString) {
JsonElement jelement = new JsonParser().parse(jsonString);
JsonObject jobject = jelement.getAsJsonObject();
JsonArray jarray = jobject.getAsJsonArray("images");
for(int i=0;i<jarray.size();i++){
JsonObject jsonObject = jarray.get(i).getAsJsonObject();
String result = jsonObject.get("ext_id").toString();
System.out.println(result);
result = jsonObject.get("height").toString();
System.out.println(result);
}
}
You can also look here

JsonArray jsonArray = (JsonArray)jObject3.get("images");
JsonObject jObject4 =(JsonObject) jsonArray.get(0);
System.out.println(jObject4.get("ext_id"));
System.out.println(jObject4.get("full_image_path"));
