Answer 1

this works for me

public static boolean isJson(String Json) {
    Gson gson = new Gson();
    try {
        gson.fromJson(Json, Object.class);
        Object jsonObjType = gson.fromJson(Json, Object.class).getClass();
        if(jsonObjType.equals(String.class)){
            return false;
        }
        return true;
    } catch (com.google.gson.JsonSyntaxException ex) {
        return false;
    }
}
