1、日期与字符串之间的转换
1 public static void main(String[] args) { 2 Date now = new Date(); 3 String d = "2017-06-13 23:23:23"; 4 5 System.out.println(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(now)); 6 try { 7 System.out.println(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse(d)); 8 } catch (ParseException e) { 9 e.printStackTrace(); 10 } 11 }
结果：
2017-06-13 23:31:12
Tue Jun 13 23:23:23 GMT+08:00 2017
2、数值字符串格式化
1 public static void main(String[] args) { 2 Double d = 1234567890.5512d; 3 System.out.println(String.format("%,.2f", d)); 4 }
结果：
1,234,567,890.55
3、日期字符串格式化
1 public static void main(String[] args) { 2 Date now = new Date(); 3 System.out.println(String.format("%tc", now)); 4 System.out.println(String.format("%tF", now)); 5 System.out.println(String.format("%tD", now)); 6 System.out.println(String.format("%tr", now)); 7 System.out.println(String.format("%tT", now)); 8 System.out.println(String.format("%tR", now)); 9 System.out.println(String.format("%1$tF %2$tT", now,now)); 10 System.out.printf("%tc%n",now); 11 System.out.printf("%tT%n",now); 12 System.out.printf("%1$s %2$tb %2$te,%2$tY%n","date:",now); 13 System.out.printf("%1$tF %2$tT",now,now); 14 }
结果：
星期三 六月 14 01:29:40 GMT+08:00 2017 2017-06-14 06/14/17 01:29:40 上午 01:29:40 01:29 2017-06-14 01:29:40 星期三 六月 14 01:29:40 GMT+08:00 2017 01:29:40 date: 六月 14,2017 2017-06-14 01:29:40
