SQL & PL/SQL

hi

I have created an object but its constructor is not compiling. here is the code example

CREATE OR REPLACE TYPE person AS OBJECT
(
empno NUMBER(4),
ename VARCHAR2(10),
job VARCHAR2(9),
mgr NUMBER(4),
hiredate DATE,
sal NUMBER(7, 2),
comm NUMBER(7, 2),
deptno NUMBER(2),

/*declaring the properties*/
CONSTRUCTOR FUNCTION person RETURN SELF AS RESULT,

MEMBER FUNCTION setaddress(x NUMBER) RETURN VARCHAR2,
MEMBER PROCEDURE setname(n VARCHAR2)
)
;

CREATE OR REPLACE TYPE BODY person IS
--
CONSTRUCTOR FUNCTION person RETURN SELF AS RESULT AS
BEGIN
RETURN NULL;
END;
--
MEMBER FUNCTION setaddress(x NUMBER) RETURN VARCHAR2 IS
BEGIN
RETURN NULL;
END;
--
MEMBER PROCEDURE setname(n VARCHAR2) IS
BEGIN
NULL;
END;
--
END;

gives error
