Java获取当前时间的年月日方法
Java 获取当前时间的年、月、日、小时、分钟、秒数。
1 public static void getDateTime() throws ParseException{2 Calendar now = Calendar.getInstance();
3 System.out.println("年: " + now.get(Calendar.YEAR));
4 System.out.println("月: " + (now.get(Calendar.MONTH) + 1) + "");
5 System.out.println("日: " + now.get(Calendar.DAY_OF_MONTH));
6 System.out.println("时: " + now.get(Calendar.HOUR_OF_DAY));
7 System.out.println("分: " + now.get(Calendar.MINUTE));
8 System.out.println("秒: " + now.get(Calendar.SECOND));
9 System.out.println("当前时间毫秒数:" + now.getTimeInMillis());
10 System.out.println(now.getTime());
11
12 Date d = new Date();
13 System.out.println(d);
14 SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
15 String dateNowStr = sdf.format(d);
16 System.out.println("格式化后的日期:" + dateNowStr);
17
18 String str = "2012-1-13 17:26:33"; //要跟上面sdf定义的格式一样
19 Date today = sdf.parse(str);
20 System.out.println("字符串转成日期:" + today);
21 }
输出结果:
2014-12-26
年: 2014
月: 12
日: 26
时: 15
分: 6
秒: 35
当前时间毫秒数:1419577595014
Fri Dec 26 15:06:35 CST 2014
Fri Dec 26 15:06:35 CST 2014
格式化后的日期:2014-12-26 15:06:35
字符串转成日期:Fri Jan 13 17:26:33 CST 2012
