How to parse given string format to dd-MMM-yyyy hh:mm:ss:aa?
提问by Star
I can get the output as Wed May 11 15:36:08 IST 2016, but how do I convert the date to a string with the required format?
我可以获得输出为Wed May 11 15:36:08 IST 2016，但是如何将日期转换为具有所需格式的字符串？
Required format is: 12-05-2016 16:05:08 pm
所需格式为： 12-05-2016 16:05:08 pm
What I tried is,
我试过的是，
public class Test {
public static void main(String args[]) throws ParseException{
String epoche="1462961108000";
Long initialLogTime = Long.valueOf(epoche);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(initialLogTime);
Calendar fromDateTime = calendar;
Calendar toDateTime = fromDateTime;
toDateTime.add(Calendar.MINUTE, 30);
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MMM-yyyy hh:mm:ss:aa");
String datestring = String.valueOf(fromDateTime.getTime());
String datestring1 = String.valueOf(toDateTime.getTime());
System.out.println(datestring); //here output is Wed May 11 15:36:08 IST 2016
System.out.println(datestring1); // here output is Wed May 11 15:36:08 IST 2016
Date dates = dateFormat.parse(datestring);
Date date1s = dateFormat.parse(datestring1);
System.out.println(dates);
System.out.println(date1s);
}
}
The error I am getting is:
我得到的错误是：
Exception in thread "main" java.text.ParseException: Unparseable date: "Wed May 11 16:05:08 IST 2016"
at java.text.DateFormat.parse(DateFormat.java:357)
at test.Test.main(Test.java:27)

You need to format your dates accordingly. This shall help you
您需要相应地格式化您的日期。这将帮助你
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss:aa");
System.out.println(dateFormat.format(fromDateTime.getTime()));
System.out.println(dateFormat.format(toDateTime.getTime()));

if you are using java 8, you can use
如果您使用的是 java 8，则可以使用
LocalDate date = LocalDate.now();
LocalDate 日期 = LocalDate.now();
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd-MMM-yyyy HH:mm:ss:aa");
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd-MMM-yyyy HH:mm:ss:aa");
System.out.println(date.format(formatter));
System.out.println(date.format(formatter));

Please try this
请试试这个

In Android, Pass String Like 11/10/2017 11:16:46to function ConvertDateTime
在 Android 中，将String Like 11/10/2017 11:16:46 传递给函数ConvertDateTime
public String ConvertUpdate(String strDate) {
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
try {
Date d = simpleDateFormat.parse(strDate);
simpleDateFormat = new SimpleDateFormat("dd MMM yy hh:mm a");
return simpleDateFormat.format(d);
} catch (ParseException e) {
e.printStackTrace();
}
return null;
}
output 10 Nov 17 11:16 AM
输出 10 11 月 17 日上午 11:16
