Hello, i had the same issue, after a couple of tries i found the solution.
For example i have a class called UserReponse, so i called this method like this

tinyDB.getObject("user",UserResponse.class);

As i could understand, this method will return the object and this parameter will cast the object it returns to the object type u pass to it.

I hope I have helped.

It's not what you are saying. 2nd argument is nothing but default argument. Please pass an object of the same class with some default value. It'll work.
With this approach: tinyDB.getObject("user",UserResponse.class); it'll work only when you have set earlier some value for key "user" else it'll give NullPointerException.

Simply update the method from

`public T getObject(String key, Class classOfT){

    String json = getString(key);
    Object value = new Gson().fromJson(json, classOfT);
    if (value == null)
        throw new NullPointerException();
    return (T)value;
}`

to
`public T getObject(String key, Class classOfT){

    String json = getString(key);
    Object value = new Gson().fromJson(json, classOfT);
    if (value == null)
        return null;
    return (T)value;
}`
