OOP Abstraction

#oop #csharp

What is abstraction?

I'll keep it fairly short. Abstraction focuses on simplifying complex systems by modeling classes based on essential characteristics, hiding unnecessary details from the user.

Someone who buys a car does not necessarily need to know how to fix it; that will be abstracted to a mechanic. The mechanic is not required to know how to design the car; that's abstracted to the engineers.

Let's look at an example (Inheritance understanding is assumed)

public class Vehicle
{
    private float speed = 0f;

    public void Accelerate()
    {
        // Physics calculations to accelerate the vehicle
    }

    public void Decelerate()
    {
        // Physics calculations to decelerate the vehicle
    }
}

public class Car : Vehicle
{
    private int doors;
    private Color color;

    public Car(int doors, Color color)
    {
        this.doors = doors;
        this.color = color;
    }
}

public class SomeCarModel : Car
{
    private string name;

    public SomeCarModel(string name, int doors, Color color) : base(doors, color)
    {
        this.name = name;
    }
}

public class CarSpawner
{
    public CarSpawner()
    {
        SomeCarModel someCarModel = new SomeCarModel("someCar", 4, new Color(100, 100, 100));

        if (userInput.w)
        {
          someCarModel.Accelerate();
        }
    }
}
