Hi,

My sample json is as following:
{
"myevents": [1234, 4567]
}

String path = "src//main//resources/sample.json";
FileReader fileReader = new FileReader(path);
JsonReader jsonReader = new JsonReader(fileReader);
Map<String, ArrayList> map = new HashMap<String, ArrayList>();
Gson gson = new Gson();
Map<String, ArrayList> map1 =gson.fromJson(jsonReader, map.getClass());

System.out.println(map1.get("myevents").toString());

Prints: [1234.0, 5678.0]

Reason:
com.google.gson.internal.bind.ObjectTypeAdapter's read method reads jsons numbers as double values, can you introduce integers, floats or double as case types? instead of treating all numbers as double values. Thanks

@OverRide public Object read(JsonReader in) throws IOException {
JsonToken token = in.peek();
switch (token) {
case BEGIN_ARRAY:
List list = new ArrayList();
in.beginArray();
while (in.hasNext()) {
list.add(read(in));
}
in.endArray();
return list;

case BEGIN_OBJECT:
  Map<String, Object> map = new LinkedTreeMap<String, Object>();
  in.beginObject();
  while (in.hasNext()) {
    map.put(in.nextName(), read(in));
  }
  in.endObject();
  return map;

case STRING:
  return in.nextString();

case NUMBER:
  return in.nextDouble();

case BOOLEAN:
  return in.nextBoolean();

case NULL:
  in.nextNull();
  return null;

default:
  throw new IllegalStateException();
}

}
