  Date d = new Date();
  System.out.println(d);   //Mon Dec 03 10:27:49 UTC 2018

  SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
  System.out.println(sdf.format(new Date()));  //03-12-2018

  LocalDate dash= java.time.LocalDate.now();

      int year;
   
      GregorianCalendar gcalendar = new GregorianCalendar();
      System.out.print("Date: ");
      System.out.print(months[gcalendar.get(Calendar.MONTH)]);
      System.out.print(" " + gcalendar.get(Calendar.DATE) + " ");
      System.out.println(year = gcalendar.get(Calendar.YEAR));
      System.out.print("Time: ");
      System.out.print(gcalendar.get(Calendar.HOUR) + ":");
      System.out.print(gcalendar.get(Calendar.MINUTE) + ":");
      System.out.println(gcalendar.get(Calendar.SECOND));
