Java 8Object Oriented ProgrammingProgramming

The “k” format in Java Date is used to format hour in 1-24 format. Use SimpleDateFormat("k") to get the same format.

// displaying hour in k format
simpleformat = new SimpleDateFormat("k");
String strHour = simpleformat.format(new Date());
System.out.println("Hour in k format = "+strHour);

Above, we have used the SimpleDateFormat class, therefore the following package is imported.

import java.text.SimpleDateFormat;

The following is an 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("E, dd MMM yyyy HH:mm:ss");
      System.out.println("Today's date and time = "+simpleformat.format(cal.getTime()));
      // displaying date
      simpleformat = new SimpleDateFormat("dd/MMMM/yyyy");
      String str = simpleformat.format(new Date());
      System.out.println("Current Date = "+str);
      // current time
      simpleformat = new SimpleDateFormat("HH.mm.ss");
      String strTime = simpleformat.format(new Date());
      System.out.println("Current Time = "+strTime);
      // displaying hour in k format
      simpleformat = new SimpleDateFormat("k");
      String strHour = simpleformat.format(new Date());
      System.out.println("Hour in k format = "+strHour);
   }
}

Output

Today's date and time = Mon, 26 Nov 2018 10:05:45
Current Date = 26/November/2018
Current Time = 10.05.45
Hour in k format = 10
