How to set 2 format types for GSON?

Question

Android

Good afternoon.
2 types of date come from the server:
1)"yyyy-MM-dd"
2)"yyyy-MM-dd HH:mm:ss".
How to set the date format for GSON, so that it would parse according to the 2nd format if there are hours and minutes, and if not, then parse by 1 ?

private static final Gson GSON = new GsonBuilder()
            .setDateFormat("yyyy-MM-dd HH:mm:ss")
            .setDateFormat("yyyy-MM-dd")
            .create();

if you do it like this, then it will always parse without time, and if you swap it, it will crash with an error if there is no time.
ps Thank you!

new GsonBuilder().registerTypeAdapter(Date.class, new DateDeserializer());

private static final String[] DATE_FORMATS = new String[] {
        "MMM dd, yyyy HH:mm:ss",
        "MMM dd, yyyy"
};


private class DateDeserializer implements JsonDeserializer<Date> {

    @Override
    public Date deserialize(JsonElement jsonElement, Type typeOF,
            JsonDeserializationContext context) throws JsonParseException {
        for (String format : DATE_FORMATS) {
            try {
                return new SimpleDateFormat(format, Locale.US).parse(jsonElement.getAsString());
            } catch (ParseException e) {
            }
        }
        throw new JsonParseException("Unparseable date: \"" + jsonElement.getAsString()
                + "\". Supported formats: " + Arrays.toString(DATE_FORMATS));
    }
}
