Public class DateTest {
Public static void main (String [] args) throws ParseException {
Date date = new Date ();
SimpleDateFormat sdf = new SimpleDateFormat ("yyyy-MM-dd HH: mm: SS ");
String date1 = sdf. format (date); // convert the date type to the String type through SimpleDateFormat
System. out. println (date1 );

String date2 = "13:10:12 ";
Date d2 = sdf. parse (date2); // convert String to date
System. out. println (d2 );

System. out. println (date. compareTo (d2); // compare two times
}
