convert a string to a date

I have been trying for more than two hour to convert a string to a date. I don't understand what i am doing wrong?

Here is my string date i receive= "Thu, 31 Jan 2013 10:48:58 GMT"

Here is my code:

try {
                SimpleDateFormat sdf = new SimpleDateFormat("EEE, dd MMM yy hh:mm:ss");
                sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
                Date d = new Date();
                d = sdf.parse(expire);
                long timestamp = d.getTime();
                return timestamp;
            } catch (ParseException e) {
                e.printStackTrace();
            }

I always get an exception, i guess my simple date format is wrong. Any on can help.

My logcat:

                SimpleDateFormat sdf = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss Z");
                Date d = new Date();
                d = sdf.parse(expire);
                Log.i("ImageFetcher","d ="+d.getDay());
                long timestamp = d.getTime();
                return timestamp;
            } catch (ParseException e) {
                e.printStackTrace();
            }

Try this code: 

  Calendar c = Calendar.getInstance();
  SimpleDateFormat df = new SimpleDateFormat("EEE, dd MMM yy hh:mm:ss");

    String Todtime = df.format(c.getTime());
    System.out.println("Time: "+Todtime);
    try {
        Date convertedDate = df.parse(Todtime);
        System.out.println("Time: "+convertedDate);
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

Change your pattern in SimpleDateFormat constructor - use yyyy, not yy.

Use this code it will help you

private String getFormatedTime(String someDate)  {
    try {
        SimpleDateFormat sdf = new SimpleDateFormat("EEE, dd MMM yy hh:mm:ss");
        Date date = sdf.parse(someDate);            
        sdf.applyPattern("h:mm a");
        String formatedDate = sdf.format(date);
        return formatedDate;            
    } catch (Exception e) {
        // TODO: handle exception
        return null;
    }
}

Try :

 DateFormat df = new SimpleDateFormat("EEE, dd MMM yy hh:mm:ss");

        try {
            Date today = df.parse("Thu, 31 Jan 2013 10:48:58 GMT");
            System.out.println("Converted Date = " + df.format(today));
        } catch (ParseException e) {
            e.printStackTrace();
        }

Try out as below:

From String to Date

String dtStart = "2010-10-15T09:27:37Z";  
SimpleDateFormat  format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");  
try {  
    Date date = format.parse(dtStart);  
    System.out.println(date);  
} catch (ParseException e) {  
    // TODO Auto-generated catch block  
    e.printStackTrace();  
}

From Date to String..

SimpleDateFormat  dateformat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");  
try {  
  Date date = new Date();  
 String datetime = dateFormat.format(date);
 System.out.println("Current Date Time : " + datetime); 
} catch (ParseException e) {  
    // TODO Auto-generated catch block  
    e.printStackTrace();  
}

I think you are missing a yy and Z.

So you will need

SimpleDateFormat sdf = new SimpleDateFormat("EEE, dd MMM yyyy hh:mm:ss Z");

you might not need the Z because of the next line of code but you certainly need the 4 y's.
