how to convert string into time format and add two hours

Question

I have the following requirement in the project.

I have a input field by name startDate and user enters in the format YYYY-MM-DD HH:MM:SS.

Answer 1

Try this one, I test it, working fine

Date date = null;
String str = "2012/07/25 12:00:00";
DateFormat formatter = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
date = formatter.parse(str);
Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
calendar.add(Calendar.HOUR, 2);
System.out.println(calendar.getTime());  // Output : Wed Jul 25 14:00:00 IST 2012

If you want to convert in your input type than add this code also

formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
str=formatter.format(calendar.getTime());
System.out.println(str);  // Output : 2012-07-25 14:00:00
