How to find Max Date in List<Object>?

Question

Consider a class User

public class User{
  int userId;
  String name;
  Date date;
}

Now I have a List

Answer 1

LocalDate maxDate = dates.stream()
                            .max( Comparator.comparing( LocalDate::toEpochDay ) )
                            .get();

LocalDate minDate = dates.stream()
                            .min( Comparator.comparing( LocalDate::toEpochDay ) )
                            .get();
