Java中SQL DATE和 UTIL DATE 的相互转换

     public  String  getStringtime (java.sql.Date  sdate ){
         java.util.Date date  = new java.util.Date(sdate.getTime());
         SimpleDateFormat sdf =  new SimpleDateFormat("yyyy-MM-dd");
         String time =sdf.format(date);
         return time;
     }
     public  java.sql.Date getSdate(String time){
         SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
         java.util.Date d = null;
        try {
            d =sdf.parse(time);

        } catch (ParseException ex) {
            ex.printStackTrace();
        }
        java.sql.Date sdate = new java.sql.Date(d.getTime());
        return sdate ;
     }
