Java日期类型与String的转换
1.String转Date

SimpleDateFormat sdf = new SimpleDateFormat("yyyymmdd");  String date = "20100701"; try {      System.out.println(sdf1.format(sdf.parse(date)));    } catch (ParseException e) {         e.printStackTrace(); /    } 

       Date date1 = new Date();           SimpleDateFormat sdf1 = new SimpleDateFormat("yyyy-MM-dd");          String str1 = sdf1.format(date1);
