I have a logical problem to understand, how create a private set of inhabitant object. Here my two classes:
package main;
import java.util.Set;
/**
* #author
* #version 0.1
*
*/
public class City {
private String name;
/**
*HERE is my Problem*/
private Set<Inhabitants> Inhabitants {
}
/**
* standard cunstructor
*/
public City(String n, ) {
setName(n);
}
/**
* Search a particular name of inhabitant
* #return object of inhabitant
*/
static Set<Inhabitants> Search(){
return inhabitants;
}
/**
* Creates a inhabitant object and
* add to the set of inhabitants of the city
*
* #param name
* #param datebirth
* #param maritalStatus
* #
*/
public void Add(String name,String datebirth,String maritalStatus) {
}
/**
* Return all inhabitants objects of the city
* #return
*/
static Set<Inhabitants> ReturnAll(){
return inhabitants;
}
/**
* Return city name
* #return
*/
static Set<Inhabitants> ReturnCityName(){
return inhabitants;
}
/**
* #return the name
*/
public String getName() {
return name;
}
/**
* #param name the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* #return the inhabitants
*/
public Set<Inhabitants> getInhabitants() {
return inhabitants;
}
/**
* #param inhabitants the inhabitants to set
*/
public void setInhabitants(Set<Inhabitants> inhabitants) {
this.inhabitants = inhabitants;
}
}
package main;
/**
* #version 0.1
*/
public class Inhabitants {
private String name;
private String datebirth;
private Boolean maritalStatus;
/**
* standard constructor
*/
public Inhabitants() {
}
/**
* #return the name
*/
public String getName() {
return name;
}
/**
* #param name the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* #return the datebirth
*/
public String getDatebirth() {
return datebirth;
}
/**
* #param datebirth the datebirth to set
*/
public void setDatebirth(String datebirth) {
this.datebirth = datebirth;
}
/**

*/
public Boolean getMaritalStatus() {
return maritalStatus;
}
/**

}
It sounds like a simple problem. You didn't need so much code:
package collections;

public class Person {
private final String name;
public Person(String name) {
if (name == null || name.trim().length() == 0) throw new IllegalArgumentException("name cannot be blank or null");
this.name = name;
}
public String getName() {
return name;
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
Person person = (Person) o;
return name.equals(person.name);
}
#Override
public int hashCode() {
return name.hashCode();
}
#Override
public String toString() {
final StringBuilder sb = new StringBuilder("Person{");
sb.append("name='").append(name).append('\'');
sb.append('}');
return sb.toString();
}

i'm developing a small web application.
That's my problem:

When executing this line i got a NumberFormatException empty string and i think it dailyLimit's or date's fault because it's empty and fromJson() method can't do what he need to do.
I've read something about a TypeAdapter that seems can fit to my case, but i don't really know how to proceed and i'm not sure is a valid solution.
Can someone help me?
The limit fields e.g. dailyLimit are empty strings in your JSON. This was suggested in JsonParseException when encountering an empty value for an int or long #472 issue but Gson team closed it because it makes no sense to parse "" as int.
One of the users provided a solution in his comment which allows to leniently parse the number values. I'd not go this route myself and fix JSON instead, but it's up to you:
public static final TypeAdapter<Number> UNRELIABLE_INTEGER = new TypeAdapter<Number>() {
#Override
public Number read(JsonReader in) throws IOException {
JsonToken jsonToken = in.peek();
switch (jsonToken) {
case NUMBER:
case STRING:
String s = in.nextString();
try {
return Integer.parseInt(s);
} catch (NumberFormatException ignored) {
}
try {
return (int)Double.parseDouble(s);
} catch (NumberFormatException ignored) {
}
return null;
case NULL:
in.nextNull();
return null;
case BOOLEAN:
in.nextBoolean();
return null;
default:
throw new JsonSyntaxException("Expecting number, got: " + jsonToken);
}
}
#Override
public void write(JsonWriter out, Number value) throws IOException {
out.value(value);
}
};
public static final TypeAdapterFactory UNRELIABLE_INTEGER_FACTORY = TypeAdapters.newFactory(int.class, Integer.class, UNRELIABLE_INTEGER);

What changes i have to do, to get specific columns from multiple data.
Thanks in advance.
You should return List<Object[]> instead of UserDetails in case of native query.
Another way is to create projection. You can use projections from Spring Data JPA http://docs.spring.io/spring-data/jpa/docs/current/reference/html/#projections.
I am trying to parse JSON Object using volley but it is giving all the values as null
I am using GsonRequest custom class to parse using GSON library

private final Gson mGson;

private final Class < T > clazz;
private final Listener < T > listener;

public GsonRequest(int method, String url, String body, Class < T > clazz, Map < String, String > headers, Response.Listener < T > listener, Response.ErrorListener errorListener) {
super(method, url, (body == null) ? null: body, listener, errorListener);
this.clazz = clazz;

Can anyone please help me out
Thought of answering my own question, may be someone can get help through this...

May be because the objects were not properly serialized so GSON was unable to parse the JSON String properly.
Others advice over the above assumption is most welcome.
i am trying to pass a custom object via retrofit2, and my question is that does the server writes my custom object to json automatically or do i have to write a php file for that. In the meanwhile I am posting successfully to the server but unable to write to json.
My aim is to write custom object to server, and write the contents of custom objects to json file.
Here is my Retrofit Api
public interface ApsaraCatalogAPI {
#GET("/apsaratrendz/data/apsara_json_document_v2.json")
Call<List<ApsaraCatalogModel>> getFeed();
#POST("/apsaratrendz/data/apsara_json_orders_document.json")
Call<Void> setOrder(#Body OrderModel orderModel);
}
Here is my calling api function
#Override
public void onClick(View v) {
int total = 0;
if(v.getId()==R.id.fabButtonCart && cartlist.size()!=0)
{
// get details from shared preferences
OrderModel orderModel = new OrderModel();
orderModel.setDate(getDate());
orderModel.setName("ssdfs");
orderModel.setEmail("sdf#gmail.com");
orderModel.setNoofitems(String.valueOf(cartlist.size()));
orderModel.setOrderno("32335");
orderModel.setPhone("9896566444");
for(int i=0; i<cartlist.size();i++){
Productdetail pd = new Productdetail();
pd.getSellingprice(String.valueOf(cartlist.get(i).getSellingPrice()));
pd.getPid(cartlist.get(i).getEANCode());
total += cartlist.get(i).getSellingPrice();
orderModel.getProductdetails().add(pd);
}
//
// now go for insertion using retrofit
requestData(orderModel);
Toast.makeText(getApplicationContext(), "Total Price : Rs."+total+"/-", Toast.LENGTH_LONG).show();
}else{
Toast.makeText(getApplicationContext(), "Cart is Empty", Toast.LENGTH_LONG).show();
}
}
And here is my service request for retrofit api, I am passing the newly created POJO OrderModel class.
private void requestData(OrderModel orderModel) {
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(ENDPOINT)
.addConverterFactory(GsonConverterFactory.create())
.build();
ApsaraCatalogAPI service = retrofit.create(ApsaraCatalogAPI.class);
Call<Void> call = service.setOrder(orderModel);
call.enqueue(new Callback<Void>() {
#Override
public void onResponse(Call<Void> call, Response<Void> response) {
if(response.isSuccessful()){
Log.d("InApi","Yipppie");

Retrofit generates the json based on your POJO and set it on the post payload.
So, in this case:
#POST("/apsaratrendz/data/apsara_json_orders_document.json")
Call<Void> setOrder(#Body OrderModel orderModel);
the body of the post will be a json representation of orderModel.
If you need to change the names of the atributtes generated in the json you can use SerializedName Annotation, its very useful:
public class OrderModel {
#SerializedName("other_name_for_json")
private String name;
Hope it helps.
