Test if object is instanceof a parameter type

Question

Is there a way to determine if an object is an instance of a generic type?

public  test(Object obj) {
    if (obj instanceof T) {
        ...
    }

If you don't want to pass Class type as a parameter as mentioned by Mark Peters, you can use the following code. Kudos to David O'Meara.

  Class type = (Class) ((ParameterizedType) getClass().getGenericSuperclass())
                  .getActualTypeArguments()[0];
  if (type.isInstance(obj)) {
      ...
  }
