How to Format Date and Time as 'dd/MM/yyyy HH:mm:ss.SS' in Java?

How to Display Date and Time in "dd/MM/yyyy HH:mm:ss.SS" Format

To format the date and time in the desired "dd/MM/yyyy HH:mm:ss.SS" format, follow these steps:

1. Use SimpleDateFormat to create a format object. Ensure the pattern is specified as:

   SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss.SS");

   Copy after login
2. Obtain the current date and time using Calendar or Date.

3. Format the date and time using the sdf object:

   String strDate = sdf.format(cal.getTime());
   Date date = sdf.parse(strDate);

   Copy after login
4. Print the formatted date and time.

The provided code example demonstrates this approach. The original code used two separate SimpleDateFormat objects to format the date, leading to different formats for the string and date outputs. By using a single SimpleDateFormat object with the correct pattern, the output can be maintained in the desired format.

The updated code:

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;

public class DateAndTime {

    public static void main(String[] args) throws Exception {
        Calendar cal = Calendar.getInstance();
        SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss.SS");
        String strDate = sdf.format(cal.getTime());
        System.out.println("Current date in String Format: " + strDate);

        Date date = sdf.parse(strDate);
        System.out.println("Current date in Date Format: " + date);
    }
}

This code will output:

Current date in String Format: 05/01/2012 21:10:17.287
Current date in Date Format: 05/01/2012 21:10:17.287
