Java Program to format hour in H (0-23) format in Java

Java 8Object Oriented ProgrammingProgramming

The “H” format in Java Date is like 0, 1, 2, 3, … 23 hour. Use SimpleDateFormat("H") to get the same format.

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

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

import java.text.SimpleDateFormat;

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("E, dd MMM yyyy HH:mm:ss Z");
      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 Z");
      String strTime = simpleformat.format(new Date());
      System.out.println("Current Time = "+strTime);
      // displaying hour in H format
      simpleformat = new SimpleDateFormat("H");
      String strHour = simpleformat.format(new Date());
      System.out.println("Hour in H format = "+strHour);
   }
}

Output

Today's date and time = Mon, 26 Nov 2018 09:56:14 +0000
Current Date = 26/November/2018
Current Time = 09.56.14 +0000
Hour in H format = 9
