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

In the provided Java code, the issue with displaying the date and time in the desired "dd/MM/yyyy HH:mm:ss.SS" format lies in the use of different SimpleDateFormat instances with different formatting patterns.

Solution:

To correctly format the date in both String and Date objects using the desired pattern, you should use the same SimpleDateFormat instance throughout the code, as follows:

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");

        // Format the date as a String
        String strDate = sdf.format(cal.getTime());
        System.out.println("Current date in String Format: "   strDate);

        // Parse the formatted string back into a Date object
        Date date = sdf.parse(strDate);
        System.out.println("Current date in Date Format: "   sdf.format(date));
    }
}

By using the same SimpleDateFormat instance with the desired pattern, the output will be:

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

This matches the specified "dd/MM/yyyy HH:mm:ss.SS" format for both String and Date representations.
