Usage of Ordinal in Enum

Code snippet:

public class EnumOrdinal{   public static void main(String args[])   {      EnumOrdinal enumOrdinal = new EnumOrdinal();      enumOrdinal.proceed();   }      enum Days {      SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY;   }      private void proceed()   {      Days ordinalDay = Days.FRIDAY; //Change this value to one of the values in the enum Days to get the respective ordinal      System.out.println("Ordinal of " + ordinalDay + " is " + ordinalDay.ordinal());   }}/*Expected output: Ordinal of FRIDAY is 5*/
