2. 44. 1. Obtaining all ordinal values using ordinal()


enum Week {

  Monday, Tuesday, Wednesday, Thursday, Friday, Saturaday, Sunday

}



public class MainClass {

  public static void main(String args[]) {



    // Obtain all ordinal values using ordinal().

    System.out.println("Here are all week constants" + " and their ordinal values: ");

    for (Week day : Week.values())

      System.out.println(day + " " + day.ordinal());



  }

}

Here are all week constants and their ordinal values: 
Monday 0
Tuesday 1
Wednesday 2
Thursday 3
