JavaSE进阶
10.5.5 java.text.DateFormat和SimpleDateFormat
完成字符串和时间对象的转化:
- String format(date)
- Date parse(string)
public static void main(String[] args) { Date date = new Date(); SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss 是本年的第几D"); System.out.println(sf.format(date)); String s = "2016-12-01 14:12:23"; SimpleDateFormat sf2 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); try { Date d = sf2.parse(s); System.out.println(d); } catch (ParseException e) { e.printStackTrace(); } } |
