Display two digits day number in Java
To display two-digit day number, use the SimpleDateFormat('dd') as shown below −
// displaying two-digit day number
f = new SimpleDateFormat("dd");
String strDay = f.format(new Date());
System.out.println("Day Number = "+strDay);Since, we have used the Format and SimpleDateFormat class above, therefore import the following packages. With that, we have also used the Date.
import java.text.Format; import java.text.SimpleDateFormat; import java.util.Date;
The following is an example.
Example
import java.text.Format;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Calendar;
public class Demo {
public static void main(String[] args) throws Exception {
// displaying current date and time
Calendar cal = Calendar.getInstance();
SimpleDateFormat simpleformat = new SimpleDateFormat("dd/MMMM/yyyy hh:mm:s");
System.out.println("Today's date = "+simpleformat.format(cal.getTime()));
// current time
Format f = new SimpleDateFormat("HH.mm.ss Z");
String strResult = f.format(new Date());
System.out.println("Time = "+strResult);
// displaying two-digit day number
f = new SimpleDateFormat("dd");
String strDay = f.format(new Date());
System.out.println("Day Number = "+strDay);
// displaying hour
f = new SimpleDateFormat("H");
String strHour = f.format(new Date());
System.out.println("Current Hour = "+strHour);
// displaying minutes
f = new SimpleDateFormat("mm");
String strMinute = f.format(new Date());
System.out.println("Current Minutes = "+strMinute);
// displaying seconds
f = new SimpleDateFormat("ss");
String strSeconds = f.format(new Date());
System.out.println("Current Seconds = "+strSeconds);
}
}Output
Today's date = 26/November/2018 08:59:48 Time = 08.59.48 +0000 Day Number = 26 Current Hour = 8 Current Minutes = 59 Current Seconds = 48
