12. Enumeration example

• A method that uses the enumeration as a parameter type:

  
      public static double getShippingAmount( ShippingType st )
      {
          double shippingAmount = 2.99;
          if ( st == ShippingType.UPS_NEXT_DAY ) {
              shippingAmount = 10.99;
          } else if ( st == ShippingType.UPS_SECOND_DAY ) {
              shippingAmount = 5.99;
          }
          return shippingAmount;
      }
  
  

• A statement that calls the method

  
      double shippingAmount =
          getShippingAmount( ShippingType.UPS_SECOND_DAY );
  
      // Wrong type, not allowed --- will not compile:
      double shippingAmount2 = getShippingAmount(1);
