JSON Question

How to deserialize a json data using GSON?

"name": "Ramesh Sippi",
"email": "ramesh.sippi@gmail.com",
"phone": 9972366543,
"officePhone": 80012345676,
"latitude": 18.5204,
"longitude": 73.8567

I tried to deserialize above JSON but it shows :

java.lang.IllegalStateException: Not a JSON Object

public class Deserializer implements JsonDeserializer<List<ContactDetails>> {
public List<ContactDetails> deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
String CONTACTS = "contacts";
return new Gson().fromJson(json.getAsJsonArray().getAsJsonObject().getAsJsonArray(CONTACTS),typeOfT);

Please help me out.Any resource or tutorial which helped you in deserialization.


json.getAsJsonArray().getAsJsonObject() is the same as json.getAsJsonObject(), and that is the cause of your exception.

You likely meant json.getAsJsonArray().get(0).getAsJsonObject().
