class GetCurrentDateAndTime

{

   public static void main(String args[])

   {

      int day, month, year;

      int second, minute, hour;

      GregorianCalendar date = new Gregorian();

      day = date.get(Calendar.DAY_OF_MONTH);

      month = date.get(Calendar.MONTH);

      year = date.get(Calendar.YEAR);

      second = date.get(Calendar.SECOND);

      minute = date.get(Calendar.MINUTE);

      hour = date.get(Calendar.HOUR);

      System.out.println("Current date is  "+day+"/"+(month+1)+"/"+year);

      System.out.println("Current time is  "+hour+" : "+minute+" : "+second);

   }

}     

There are errors showing in Eclipse related to this program. These errors include the declared package not matching the expected package. Also, variables like the java.util.scanner, sun.util.scanner, GeorgianCalender, and Calender cannot be resolved.
