jdbc-updating spatial data

i looked to the next link:

http://java.sun.com/docs/books/tutorial/jdbc/basics/connecting.html

I want to update spatial data.To the previous link i found how to update tables but not how to update tables which contain spatial data.For example:

CREATE TABLE customers (

customer_id NUMBER,

last_name VARCHAR2(30),

first_name VARCHAR2(30),

street_address VARCHAR2(40),

city VARCHAR2(30),

state_province_code VARCHAR2(2),

postal_code VARCHAR2(9),

cust_geo_location SDO_GEOMETRY);

INSERT INTO customers VALUES

(1001,'Nichols', 'Alexandra',

'17 Maple Drive', 'Nashua', 'NH','03062',

SDO_GEOMETRY(2001, 8307,

SDO_POINT_TYPE (-71.48923,42.72347,NULL), NULL, NULL));

if i want to update the costumer position (-71.48923,42.72347) how can i do this;;;
