import java.text.*; 
import java.util.*; 
  
public class DateFormat_Demo { 
    public static void main(String[] args) 
    { 
        // Initializing DateFormat 
        DateFormat DFormat 
            = DateFormat.getDateTimeInstance(); 
  
        // Displaying the formats 
        Date date = new Date(); 
        String str_Date1 
            = DFormat.format(date); 
        System.out.println("The Original: "
                           + (str_Date1)); 
  
        // Using clone() 
        System.out.println("Is the clone equal? "
                           + DFormat.clone() 
                                 .equals(DFormat)); 
    } 
}
