import java.text.*;
import java.util.Calendar;

public class SimpleDateFormat_Demo {
    public static void main(String[] args)
        throws InterruptedException
    {
        SimpleDateFormat SDFormat
            = new SimpleDateFormat("MM/dd/yyyy");

        Calendar cal = Calendar.getInstance();

        // Displaying the actual date
        System.out.println("The original Date: "
                           + cal.getTime());

        // Using format() method for conversion
        String curr_date
            = SDFormat.format(cal.getTime());
        System.out.println("Formatted Date: "
                           + curr_date);
    }
}

import java.text.*;
import java.util.Calendar;

public class SimpleDateFormat_Demo {
    public static void main(String[] args)
        throws InterruptedException
    {
        SimpleDateFormat SDFormat
            = new SimpleDateFormat();

        // Initializing the calendar Object
        Calendar cal = Calendar.getInstance();

        // Displaying the actual date
        System.out.println("The original Date: "
                           + cal.getTime());

        // Using format() method for conversion
        String curr_date = SDFormat.format(cal.getTime());
        System.out.println("Formatted Date: "
                           + curr_date);
    }
