I have this json and need help for parsing and and displaying the Placetype _Name and Place details.

An easy solution to handle the JSON element name that starts with “-“, which is a character that cannot be used to start a Java identifier name, is to make use of the @SerializedName annotation.

import java.io.FileReader;
import java.util.List;

import com.google.gson.Gson;
import com.google.gson.annotations.SerializedName;

public class GsonFoo
{
  public static void main(String[] args) throws Exception
  {
    Response response = new Gson().fromJson(new FileReader("input.json"), Response.class);
    System.out.println(response.PlacesList.PlaceType.get(0).Name);
    System.out.println(response.PlacesList.PlaceType.get(0).Places.Place.get(0).name);
    System.out.println(response.PlacesList.PlaceType.get(0).Places.Place.get(0).description);
  }
}

class Response
{
  PlacesList PlacesList;
}

class PlacesList
{
  List<PlaceType> PlaceType;
}

class PlaceType
{
  @SerializedName("-Name")
  String Name;
  Places Places;
}

class Places
{
  List<Place> Place;
}

class Place
{
  String name;
  String latitude;
  String longitude;
  String description;
}

Output:

Airport
Juhu Aerodrome
Juhu Aerodrome is an airport that serves the metropolitan
