java.text.ParseException: Unparseable date

Question

In my project, I am trying to parse date format like this "Mon Oct 20 00:00:00 GMT+06:30 2014" to dd-MM-yyyy but I got the following error. I am hoping someone to solve me this problem.

Thanks,

10-20 13:03:01.390: W/System.err(23409): java.text.ParseException: Unparseable date: "Mon Oct 20 00:00:00 GMT+06:30 2014" (at offset 0)

parseDate.java

SimpleDateFormat formatter_date = new SimpleDateFormat("dd-MM-yyyy");
String sdate="Mon Oct 20 00:00:00 GMT+06:30 2014";
    try {
        Date _date= formatter_date.parse(sdate);
        holder.txtDate.setText(String.valueOf(_date));

    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

can we see the declaration of formatter_date?

use this code

public static String parseTodaysDate(String time) {



    String inputPattern = "EEE MMM d HH:mm:ss zzz yyyy";

    String outputPattern = "dd-MM-yyyy";

    SimpleDateFormat inputFormat = new SimpleDateFormat(inputPattern);
    SimpleDateFormat outputFormat = new SimpleDateFormat(outputPattern);

    Date date = null;
    String str = null;

    try {
        date = inputFormat.parse(time);
        str = outputFormat.format(date);

        Log.i("mini", "Converted Date Today:" + str);
    } catch (ParseException e) {
        e.printStackTrace();
    }
    return str;
}

@MeenalSharma,I think you miss one 'd' inputPattern.

@MeenalSharma , change your parsing format dd instead of d

NB : if the error persists you have to add the local information pour the inputFormat. SimpleDateFormat inputFormat = new SimpleDateFormat(inputPattern, Locale.ENGLISH);

Replace

SimpleDateFormat formatter_date = new SimpleDateFormat("dd-MM-yyyy");

with

SimpleDateFormat formatter_date = new SimpleDateFormat("EEE MMM dd HH:mm:ss zzz yyyy", Locale.ENGLISH);

Because that's the way the string is made. The input value would have to be formatted that way. But the input is not "20-10-2014"...

Great answer, simply true!

Unfortunately, the accepted answer has missed a crucial thing, Locale while parsing the date-time string. Therefore, that code will work merely by coincidence - only when the JVM on which it is executed, has an English Locale set. Check Always specify a Locale with a date-time formatter for custom formats to learn more about it.

`java.time`

In March 2014, Java 8 introduced the modern, java.time date-time API which supplanted the error-prone legacy java.util date-time API. Any new code should use the java.time API.

Solution using modern date-time API

Your date-time string has a time zone offset. So, parse your date-time string into an OffsetDateTime using DateTimeFormatter.ofPattern("EEE MMM dd HH:mm:ss OOOO uuuu", Locale.ENGLISH) and format it using DateTimeFormatter.ofPattern("dd-MM-uuuu", Locale.ENGLISH).

Demo:

public class Main {
    private static final DateTimeFormatter parser = DateTimeFormatter.ofPattern("EEE MMM dd HH:mm:ss OOOO uuuu",
            Locale.ENGLISH);

    private static final DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd-MM-uuuu",
            Locale.ENGLISH);

    public static void main(String[] args) {
        OffsetDateTime odt = OffsetDateTime.parse("Mon Oct 20 00:00:00 GMT+06:30 2014", parser);
        System.out.println(odt);

        // Formatted output
        System.out.println(odt.format(formatter));
    }
}

Output:

2014-10-20T00:00+06:30
20-10-2014

Online Demo

Note: For whatever reason, if you need an instance of java.util.Date from this object of OffsetDateTime, you can do so as follows:

java.util.Date date = Date.from(odt.toInstant());
