How can I convert a String to a Date and then to a different format?

Question

Actually I wanted to convert one String to date and then I need to format it in to one another format..

The String I have is

 String val="Wed Jan 08 08:49:13 GMT+05:30 2014";

To convert it to

 2014-01-30 10:14:18  , this format

Is it possible to do this I tried some method like

       SimpleDateFormat df = new SimpleDateFormat("dd-MMM-yyyy");
        String formattedDate = df.format(c.getTime());

        Calendar cal =   Calendar.getInstance(TimeZone.getTimeZone("GMT+1:00"));
          // Date currentLocalTime = ;
            DateFormat date = new SimpleDateFormat("HH:mm:ss:mmss a");

But nothing worked

Telling us that nothing worked is not helpful. Tell us how and why it didn't work. — Sotirios Delimanolis

If you have a date string, you need to parse it into a Date before you can format it differently. — Sotirios Delimanolis

Of course it is possible but I don't see how your code is gonna do that. For date parsing I recommend Joda Time, which parses rather well. Anyway, how about writing a JUnit test case or two? — David Tonhofer

Your format string for parsing doesn't match the example date you have given.

You could try something like the following:

    String val = "Wed Jan 08 08:49:13 GMT+05:30 2014";
    DateFormat inFmt = new SimpleDateFormat("EEE MMM dd HH:mm:ss Z yyyy");
    Date date = inFmt.parse(val);
    DateFormat outFmt = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    outFmt.setTimeZone(TimeZone.getTimeZone("GMT+1:00"));
    System.out.println(outFmt.format(date));

Note the following correspondences in the first two lines:

Wed -> EEE
Jan -> MMM
08 -> dd
etc.
