public final int ordinal()

public class EnumOrdinal {

     // enum showing Laptop prices

     enum Laptop {

           Dell(1600), HP(1500), Lenovo(1000);

           int price;

           Laptop(int p) {

                price = p;

           }

           int showPrice() {

                return price;

           }

     }

     public static void main(String args[]) {

           System.out.println("Laptops :");

           for(Laptop lap : Laptop.values()) {

                System.out.println("Ordinal value of "+lap.name()+

                           " is "+lap.ordinal());

           }

           System.out.println("HP index "+ Laptop.HP.ordinal());

     }

}
