Leer Uitdaging: Methode-overbelasting

In dit oefenprobleem krijg je een ShippingCalculator-klasse met een methode genaamd CalculateShippingCost. De methode moet worden overbelast om verschillende scenario's van verzendkosten te ondersteunen op basis van het gewicht en de bestemming.

Je taak is om de lege plekken (___) op de juiste manier in te vullen om de berekeningen in de CalculateShippingCost-methode te voltooien voor zowel lokale als internationale zendingen.

using System;

public class ShippingCalculator
{
    // Method to calculate shipping cost for local shipments
    public double CalculateShippingCost(double weight)
    {
        // Local shipments have a fixed rate of $5 per kilogram
        return weight * ___;
    }

    // Method to calculate shipping cost for international shipments
    // It has two parameters 'weight' and an additional 'destinationCountry' which is of type 'string'
    ___
    {
        // International shipments have a base rate of $10 per kilogram
        // Additional $3 per kilogram for shipments to Canada
        // Additional $5 per kilogram for shipments to other countries
        double baseRate = ___;
        double additionalRate = destinationCountry.ToLower() == "canada" ? ___ : ___;

        return weight * (baseRate + additionalRate);
    }
}

class ConsoleApp
{
    static void Main()
    {
        ShippingCalculator calculator = new ShippingCalculator();

        // Test local shipment
        double localCost = calculator.CalculateShippingCost(2);
        Console.WriteLine($"Local Shipment Cost: ${localCost}");

        // Test international shipment to Canada
        double internationalToCanadaCost = calculator.CalculateShippingCost(2, "Canada");
        Console.WriteLine($"International Shipment to Canada Cost: ${internationalToCanadaCost}");

        // Test international shipment to other countries
        double internationalToOtherCost = calculator.CalculateShippingCost(2, "Germany");
        Console.WriteLine($"International Shipment to Other Country Cost: ${internationalToOtherCost}");
    }
}

Je moet de CalculateShippingCost overbelasten. Daarom moet de nieuwe methode dezelfde naam hebben, maar andere parameters. De vereiste parameters worden in de opmerkingen gegeven.

        double baseRate = 10;
        double additionalRate = destinationCountry.ToLower() == "canada" ? 3 : 5;

        return weight * (baseRate + additionalRate);
    }
}

class ConsoleApp
{
    static void Main()
    {
        ShippingCalculator calculator = new ShippingCalculator();

        // Test local shipment
        double localCost = calculator.CalculateShippingCost(2);
        Console.WriteLine($"Local Shipment Cost: ${localCost}");

        // Test international shipment to Canada
        double internationalToCanadaCost = calculator.CalculateShippingCost(2, "Canada");
        Console.WriteLine($"International Shipment to Canada Cost: ${internationalToCanadaCost}");

        // Test international shipment to other countries
        double internationalToOtherCost = calculator.CalculateShippingCost(2, "Germany");
        Console.WriteLine($"International Shipment to Other Country Cost: ${internationalToOtherCost}");
    }
