Convert string Date into timestamp in Android?

Question

I want to convert my date (which is in String format), e.g. 13-09-2011, into Timestamp. I used below code but I got the 2011-09-13 00:00:00.0 as a result. But I want Timestamp like,1312828200000 format.

I cannot understand how to convert that.

My code:

String str_date="13-09-2011";
DateFormat formatter ; 
Date date ; 
formatter = new SimpleDateFormat("dd-MM-yyyy");
date = (Date)formatter.parse(str_date); 
java.sql.Timestamp timeStampDate = new Timestamp(date.getTime());
System.out.println("Today is " +timeStampDate);

Answer 1

If you use getTime() of Date object you will get time in millisecond. No need to use Timestamp to get your result.

String str_date="13-09-2011";
DateFormat formatter = new SimpleDateFormat("dd-MM-yyyy");
Date date = (Date)formatter.parse(str_date); 
System.out.println("Today is " +date.getTime());

The above code will print something like 1312828200000 you need and this is long value.
