C# C# Objects Methods Return Values

How can we compile before a point is created?

When we write the method in Map

public bool OnMap(Point point) { } Without creating a point in Main() how come we can compile it?

Is there already a point? I'm confused

you're declaring the variable point inside of your ( ). Point is a class that we defined in Point.cs. so Point point defines point as the name of your variable. the same would happen if you said Point fred.

In this method declaration, you're just indicating that the method will accept a Point object as an argument (and refer to it with the name "point"). Since you're only defining the method here, and not calling it, you don't need an actual Point object yet.

Very helpful!
