My example for objects:
create or replace type date_object as object
  centure number,
  year    number,
  month   number,
  day     number,
  hour    number,
  minute  number,
  second  number,
  daypart number,
  week    number,
  constructor function date_object(p_dt date)
    return SELF as result
create or replace type body date_object is
  constructor function date_object(p_dt date)
    return SELF as result
  as
  begin
    SELF.centure:= trunc(to_char(p_dt,'YYYY')/100);
    SELF.year:=    to_char(p_dt,'YYYY');
    SELF.month:=   to_char(p_dt,'MM');
    SELF.day:=     to_char(p_dt,'DD');
    SELF.hour:=    to_char(p_dt,'HH24');
    SELF.minute:=  to_char(p_dt,'MI');
    SELF.second:=  to_char(p_dt,'SS');
    SELF.daypart:= p_dt-trunc(p_dt,'DD');
    SELF.week:=    to_char(p_dt,'IW');
    return;
  end;
end;
select date_object(sysdate),
       date_object(sysdate).year
