Using instance of one class in other C#

During the c# training, the trainer uses the instance of class point in other classes. I get the way the classes work, but i don't get the concept of using classes in other classes. Maybe i missed something?

class void Point (int x, int y)

class void MapLocation (Point point)

can anyone explain this concept

Thanks Remco

Hello

You have a class called Car .........  assume for now that the car has an attribute of Type Driver  ... someone has to drive the car ... right?   no it not a driver-less car ... yet :-)

You have Class called Driver  .........  just for demo

class Car(){
    private Driver driver;

    //constructor
    public Car(Driver driver) {
       this driver = driver;   //put a driver in a car
    }
}



class Driver(){
.
.
.
.
}


Driver meDriver = new Driver()
Car myCar  = new Car(meDriver) /// getting myself a Car :-)


same thing with the Map and Point.   A Map ia a Class that takes a Point object or objects as attributes.

Hope this help 

the code above is pseudo code for demo only.

Thanks
