Java代码-Date转换

       //Date 转 String
        public static String getStringDate(Date date) {
   
                   SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd_HH:mm:ss");
                   String dateString = formatter.format(date);
                   return dateString;
                }
        // String 转 Date
         public static Date getDateString(String strDate) {
   
          SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd_HH:mm:ss");
          ParsePosition pos = new ParsePosition(0);
          Date strtodate = formatter.parse(strDate, pos);

    //sql与util date互转
    java.util.Date uD1 = new java.util.Date();
    System.out.println(uD1);
    java.sql.Date sD = new java.sql.Date(uD1.getTime());
    java.sql.Time tD = new java.sql.Time(uD1.getTime());
    System.out.println(sD);
    System.out.println(tD);
    
    java.sql.Timestamp t = new Timestamp(sD.getTime());
    System.out.println(t);
