c# constructors

why do we do this in the body of the constructor "X = x; Y = y; "

class Point { public readonly int X; public readonly int Y;

    public Point(int x, int y)
    {
         X = x;
         Y = y; 
    }
}

Those assignments copy the values that were passed to the constructor (the lower-case x and y) into the fields (or properties) of the object (capital X and Y) so they can be saved and used later.
