get current date and time

Question

I'm kind of stuck on date and time. I want my program to create the date like this "20121217". The first 4 letters are the year, the second 2 letters are the month and the last 2 are the day. year+month+day

The time is "112233" hour+minute+second

Thanks for your help!

Answer 1

That's a formatting issue. Java uses java.util.Date and java.text.DateFormat and java.text.SimpleDateFormat for those things.

DateFormat dateFormatter = new SimpleDateFormat("yyyyMMdd hhmmss");
dateFormatter.setLenient(false);
Date today = new Date();
String s = dateFormatter.format(today);

Answer 2

You can do something like this:

Calendar c = Calendar.getInstance();
String date = c.get(Calendar.YEAR) + c.get(Calendar.MONTH) + c.get(Calendar.DATE);
String time = c.get(Calendar.HOUR) + c.get(Calendar.MINUTE) + c.get(Calendar.SECOND);
