Object

Question

I still don't understand what an "object" is 😢.
what does it mean an "concrete entity" or "an instance of the class"?

Answer 1

Well, the Object is something that is abstract. The best example is to take something from the real world.

Let's have an example:

Car

So let's write a class for Car.
We can give it some properties, like Make, Name, Type and so on.

public class Car
{
public string Make;
public string Name;
public string Type;
}

Now we have a class for Car. In this case we can't do anything with it, we first have to make an instance of the class that we can use.

So we do:
Car myCar = new Car();

this creates an instance (myCar) of the object Car that we can then use.
We can give it a name:
myCar.Name = "M3";
And we can say it's a BMW, and it's a sport car:
myCar.Make = "BMW";
myCar.Type = "Sport";

So we have an abstract class that represents a real world object, in our case Car. And a BMW M3 Sport is one instance of this object - myCar.

Hope this helps.

Happy coding!
