将以毫秒为单位的时期转换为日期和时间：Java [英] Converting Epoch in milliseconds into Date and Time: Java

问题描述

我有一个以毫秒为单位的时期值。我想从两个字符串中单独提取日期（02/11/2013）和时间（09:23 am）。有人可以帮忙吗？

谢谢

解决方案

我想提取日期（02 / 11/2013）和时间（09:23 am）分开从两个字符串。

请参阅 SimpleDateFormat javadoc | SimpleDateFormat turorial 。这将帮助您解决问题。

 日期date = new Date（epoch）; //'epoch'in long 
 
 SimpleDateFormat formatter = new SimpleDateFormat（MM / dd / yyyy）; 
 String dateString = formatter.format（date）; 
 
 formatter = new SimpleDateFormat（hh：mm a）; //a是AM / PM标记
 String time = formatter.format（date）; 
  

I have an epoch value in milliseconds. I would like extract the date (02/11/2013) and time (09:23 am) from this separately in two strings.

could someone please help with that? Thanks

"I would like extract the date (02/11/2013) and time (09:23 am) from this separately in two strings."

See SimpleDateFormat javadoc | SimpleDateFormat turorial. This will help you with your problem.

Date date = new Date(epoch); // 'epoch' in long

SimpleDateFormat formatter = new SimpleDateFormat("MM/dd/yyyy");
String dateString = formatter.format(date);

formatter = new SimpleDateFormat("hh:mm a"); //The "a" is the AM/PM marker
String time = formatter.format(date);
