How can you protect your data using the HTTPS protocol?

The HTTP request to the interface is made by calling methods or accessing properties of the class instance that implements this interface. You cannot instantiate the interface itself.

Example:

// Interface declaration
public interface ILogger
{
    void LogMessage(string message);
}

// Class implementing the interface
public class ConsoleLogger : ILogger
{
    public void LogMessage(string message)
    {
        Console.WriteLine(message);
    }
}

// Using the interface
public class Application
{
    private readonly ILogger _logger;

    public Application(ILogger logger) // Dependency on interface
    {
        _logger = logger;
    }

    public void Run()
    {
        _logger.LogMessage("Application started."); // Call method via interface
    }
}

// Entry point
public class Program
{
    public static void Main(string[] args)
    {
        ILogger logger = new ConsoleLogger(); // Create an instance of class implementing interface
        Application app = new Application(logger);
        app.Run();
    }
}

Main principles:

• Polymorphism: Allows to work with different implementations of the interface through a common type.
• Abstraction: Hides implementation details and works only with the contract defined by the interface.
• Instance usage: Calls to the interface always happen through an instance of a class that implements the interface methods and properties.
