Display day number with SimpleDateFormat('d') in Java

To display the day number, use the SimpleDateFormat('d') as shown below −

Format f = new SimpleDateFormat("d"); 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 day number f = new SimpleDateFormat("d"); 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 08:57:31 Time = 08.57.31 +0000 Day Number = 26 Current Hour = 8 Current Minutes = 57 Current Seconds = 31
