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

 Live Demo

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
