How to get value from json using restassured

I have json and there is array of 'products'.
{
"data": [
{
"contact_id": "...",
"email": "...",
"first_name": "...",
"hash_campaign": "",
"hash_campaign_valid_to_date": null,
"hash_password": "",
"last_name": "...",
"loans": [
],
"max_available_loan_amount": 2000.00,
"middle_name": "P",
"mobile": "...",
"personal_id": "...",
"product_code": 2,
"products": [
{
"available_loan_terms": [
15,
21,
30,
7,
45
],
"default_amount": 0,
"default_term": 15,
"document_required": 0,
"max_available_loan_amount": 2000.00,
"max_loan_amount": 0,
"max_monthly_payment": 0.00,
"product_code": 2
},
{
"available_loan_terms": [
3,
6,
4,
5
],
"default_amount": 0,
"default_term": 0,
"document_required": 0,
"max_available_loan_amount": 4000.00,
"max_loan_amount": 0,
"max_monthly_payment": 1300.00,
"product_code": 101
},
{
"available_loan_terms": [
3,
6,
4,
5
],
"default_amount": 0,
"default_term": 0,
"document_required": 0,
"max_available_loan_amount": 3000.00,
"max_loan_amount": 0,
"max_monthly_payment": 1510.00,
"product_code": 100
}
],
"scoring_through_zoral": "0"
}
],
"description": "...",
"requestId": "...",
"status": 8888
}
I would like to get values of fields 'default_term' and 'max_available_loan_amount' only for product with code 2.
I use restassured
I've tried
List<List> lists = response.body().jsonPath().getList("data.products");
but this code returns list with only one item, I mean all products in one item...
how can I get information for first item in products array from this json ???

Step 1: Create POJO to mapping
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.Data;
#Data
#JsonIgnoreProperties(ignoreUnknown = true)
public static class Product {
#JsonProperty("default_term")
private int default_term;
#JsonProperty("max_available_loan_amount")
private double max_available_loan_amount;
}
Step 2: Extract response and deserialize to object.
Product product = ...jsonPath().getObject("data[0].products.find {it.product_code == 2}", Product.class);
System.out.println(product);
//Product(default_term=15, max_available_loan_amount=2000.0)

This could work
List<Integer> li_defaultTerm = response.getBody().jsonPath().get("$..products[?(#.product_code=='2')].default_term");
System.out.println(li_defaultTerm.get(0));
//15
List<Double> li_MaxAvailLoanAmount = response.getBody().jsonPath().get("$..products[?(#.product_code=='2')].max_available_loan_amount");
System.out.println(li_MaxAvailLoanAmount.get(0));
//2000.0

Convert the flat Java Object that was created from the DB read, into nested Json object

The threaded comments are stored in Database as flat records with commenId and ParentCommentId. Like below.
commentId : 1
userId    : 815
userFName:Joe
userLName:Doe
timeStamp:12345678888
commentText:""
parentCommentId:0
commentId : 2
userId    : 615
userFirstName:Ken
userLastName:Tait
timeStamp:12345678988
commentText:"Comment text"
parentCommentId:1
commentId : 3
userId    : 415
userFirstName:Brain
userLastName:Dell
timeStamp:12345678
commentText:"Comment text"
parentCommentId:0
I build the Java object using the following Java class
public class Comment {
int commentId;
int userId;
String userFName;
String userLName;
long timeStamp;
String commentText;
int parCommId;
}
List<Comment> comments;
I have the List of comments object. Now I have to traverse the list and convert this list of comment object into nested Json object. The comment objects with parCommId == 0 are the top level comment and the other comment objects (parCommId != 0) should be nested under the commentId of the comment object.
In the above example, the output should be nested like below
CommentId_1
CommentId_2
CommentID_3

As suggested in the comments, let's add a List<Comment> field in Comment.class.
Then, assuming the input from the DB is:
List<Comment> comments = Arrays.asList(
new Comment(1, 6, "John", "Snow", 0, "asd", 0),
new Comment(2, 6, "Tif", "Snow", 0, "asd2", 1),
new Comment(3, 6, "Yur", "Snow", 0, "asd", 2),
new Comment(4, 6, "Mrr", "Snow", 0, "asd", 0),
new Comment(5, 6, "Mrr", "Snow", 0, "asd", 2)
);
You can do the following:
Map<Integer, List<Comment>> parentToComments = comments.stream()
.collect(Collectors.groupingBy(Comment::getParCommId));
comments.forEach(comment -> {
List<Comment> children = parentToComments.get(comment.getCommentId());
comment.setChildren(children);
});
ObjectMapper objectMapper = new ObjectMapper();
String commentsJson = objectMapper.writeValueAsString(parentToComments.get(0));
Output:
[{
"commentId": 1,
"userId": 6,
"userFName": "John",
"userLName": "Snow",
"timeStamp": 0,
"commentText": "asd",
"parCommId": 0,
"children": [{
"commentId": 2,
"userId": 6,
"userFName": "Tif",
"userLName": "Snow",
"timeStamp": 0,
"commentText": "asd2",
"parCommId": 1,
"children": [{
"commentId": 3,
"userId": 6,
"userFName": "Yur",
"userLName": "Snow",
"timeStamp": 0,
"commentText": "asd",
"parCommId": 2,
"children": null
}, {
"commentId": 5,
"userId": 6,
"userFName": "Mrr",
"userLName": "Snow",
"timeStamp": 0,
"commentText": "asd",
"parCommId": 2,
"children": null
}]
}]
}, {
"commentId": 4,
"userId": 6,
"userFName": "Mrr",
"userLName": "Snow",
"timeStamp": 0,
"commentText": "asd",
"parCommId": 0,
"children": null
}]

And I am trying to get all DataFlagType values using parallelStream() and forEach().
This is the code I have written but I am getting error:
jsonArray = (JSONArray) json.get("LiveSessionDataCollection");
jsonArray.parallelStream().forEach(
x -> ((JSONObject) dataFlagType = (JSONObject) jsonArray.get(1)));
I don't know exactly how to work with parallelStream(). How can I achieve getting all DataFlayType values from the json array (as int)?

You first need to get a stream of all object's DataFlagType attribute then collect it in a list:
jsonArray.parallelStream().map(x->
((JSONObject)x).get("DataFlagType")).collect(Collectors.toList())
Output:
[264,264,264]

How to get Json data from java website by using Codeigniter3?

I'm going to select data which return value from third party website as below Json objects format and that website build in Java languages and tomcat database.
Issue How to get contain from that websites?

Please try code below
$URL = "http://103.5.126.24/PalmHallServer/coodraw/coodraw!queryAllProduct.action";
$content = file_get_contents($URL); // get json data using file_get_content
$content_arr = json_decode($content); // json data to php array.
OR if you wish to use curl
$s = curl_init();
curl_setopt($s,CURLOPT_URL,$this->_url);
curl_setopt($s,CURLOPT_RETURNTRANSFER,true);
$result = curl_exec($s);
curl_close($s);
$content_arr = json_decode($result); // json data to php array.
Then you could print_r($content_arr) and check "LuckDrawProductList" the key or access $content_arr['LuckDrawProductList][0]

filter a json array (which has million items) based on search criteria

I am at loss of finding the best way to filter a json array (which has million items) based on some search criteria which keeps on changning.
eg: find all items based on region_id and pool_id
The json array format as below
[
{
"url": "webservices/rest/resources/1/",
"id": 1,
"name": "con A",
"is_parent": 1,
"account_id": 1,
"pool_id": 4,
"region_id": 5,
"market_id": 1,
"baseline_type": "Type 1",
"is_producer": 0,
"utilisation_type": 0,
"forecasting_algorithm": "Clipped nominal capacity",
"availability_protocol": null,
"communication_protocol": "OPC",
"activation_protocol": [
" Demo"
],
"installed_capacity": 2000.0,
"nominal_capacity": 1000.0,
"positive_tolerance": 300.0,
"negative_tolerance": 300.0,
"capacity_fee": 20.0,
"energy_fee": 20.0,
"activation_fee": 10.0,
"parent_resource": null
},
{

"is_parent": 1,
"account_id": 2,
"pool_id": 1,
"region_id": 4,
"market_id": 1,
"baseline_type": "Type 1 DW",
"is_producer": 1,
"utilisation_type": 0,
"forecasting_algorithm": "Clipped nominal capacity",
"availability_protocol": null,
"communication_protocol": " Demo",
"activation_protocol": [
" Demo"
],
"installed_capacity": 3000.0,
"nominal_capacity": 1000.0,
"positive_tolerance": 300.0,
"negative_tolerance": 300.0,
"capacity_fee": 20.0,
"energy_fee": 20.0,
"activation_fee": 10.0,
"parent_resource": null
},
.
.
. // million items
]
I tried using the following api's in java
Jackson api for converting the json to java objects.
Google Guava api for filtering java objects.
Is it the best procedure to filter the json data? If not, please advice.
