Explanation of Options

1. DateFormat: This is an abstract class in Java that defines methods for formatting and parsing dates.
2. SimpleDateFormat: This is a concrete class that extends DateFormat and allows for formatting and parsing of dates in a locale-sensitive manner.
3. SimpleFormat: This is not a standard class in Java for date formatting.
4. DateConverter: This option could refer to a custom utility or a library, but it's not a standard Java class.

Final Answer

You should use SimpleDateFormat to format dates in Java. Here's a simple example of how you can use it:

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

public class DateExample {
    public static void main(String[] args) {
        // Create a date object
        Date date = new Date();

        // Create a SimpleDateFormat object with desired format
        SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");

        // Format the date
        String formattedDate = sdf.format(date);

        // Output the formatted date
        System.out.println("Formatted Date: " + formattedDate);
    }
}

In this example, the current date is formatted to "dd-MM-yyyy" format. Adjust the pattern in SimpleDateFormat as needed for your specific date format requirements.
