Can the code "timestamp = System.currentTimeMillis()" be changed to display the date and time in a specific format such as "DD-MM-YYYY HH:MM:SS"?

Yes, the code can be changed to display the date and time in a specific format using the SimpleDateFormat class. Here's an example:

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

public class TimestampExample 
{
    public static void main(String[] args) 
    {
        SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
        String dateAndTime = sdf.format(new Date(System.currentTimeMillis()));
        System.out.println(dateAndTime);
    }
}

This code creates a SimpleDateFormat object with the desired date and time format, then formats the current date and time as a string using the format() method. Finally, it prints the date and time string to the console.
