java Unparseable date:

Question

how to parse this date ?

Mon Jul 29 02:00:00 CEST 2013

the code:

    public class HelloWorld{

     public static void main(String []args){

        try {
                String startdateString = "Mon Jul 29 02:00:00 CEST 2013";
        SimpleDateFormat fromUser2 = new SimpleDateFormat("EEE MMM d hh:mm:ss z yyyy");

            startdateString = myFormat.format(fromUser2.parse(startdateString));
        } catch (ParseException e) {
            e.printStackTrace();
        }
     }
}

i am getting following exception

java.text.ParseException: Unparseable date: "Mon Jul 29 02:00:00 CEST 2013"

16:13:57,761 ERROR [stderr] (http-/0.0.0.0:8080-1)  at java.text.DateFormat.parse(Unknown Source)

How are you creating this `myFormat` variable? I changed it to `fromUser2` and runs without problems. — Luiggi Mendoza, Jan 23 '14 at 15:22

@Fernando: Ah - agreed, "Mon" won't be a valid day in the default locale. Voting as duplicate. — Andrzej Doyle, Jan 23 '14 at 15:24

You don't provide any Locale and the code won't work if you don't run it on an english locale (as US or UK).

The following code (corrected) work for me:

try {
    String startdateString = "Mon Jul 29 02:00:00 CEST 2013";
    SimpleDateFormat fromUser2 = new SimpleDateFormat("EEE MMM dd hh:mm:ss z yyyy", Locale.ENGLISH);

    System.out.println(fromUser2.parse(startdateString));
} catch (ParseException e) {
    e.printStackTrace();
}

Instead posting two similar answers, provide just one and edit it. – Luiggi Mendoza Jan 23 '14 at 15:28
By the way, I've tested it using `d` instead of your proposal `dd` and works fine... – Luiggi Mendoza Jan 23 '14 at 15:28
@LuiggiMendoza I'm not sure if this is a problem with SO or with my browser, but I never wanted to post twice. – LaurentG Jan 23 '14 at 17:08
@LaurentG No need to write Locale and dd. There is just problem of using object of SimpleDateFormat to format the date. – ravibagul91 Jan 24 '14 at 05:01

You need to format your date using SimpleDateFormat's object.

Replace

startdateString = myFormat.format(fromUser2.parse(startdateString));

By

startdateString = fromUser2.format(fromUser2.parse(startdateString));
