Hello: 1. I view the source code of java.sql.* found Connection, ResultSet are Interface. I feel confuse where and how java implements those Interface really ? 2. I want extend functions of ResultSet like add new method, How should I do it ? Thanks in advance. bubble chen(2000/9/15 AM 08:46:42) [EMAIL PROTECTED] ========================================================== PC home 免費電子信箱，申請請至: http://www.pchome.com.tw PC home Online 網路家庭 會員第一，台灣最大的入口網站 ==========================================================
