create new rectangle object
r1 = new Rectangle(100, 200, 150, 150);
}
// class description
class Rectangle {
//class constructor
Rectangle(int x, int y, int w, int h) {
rect(x, y, w, h);
}
}

Creating a neighborhood
Hopefully, this last sketch makes some sense. Don’t worry if it doesn’t yet. Also, you’d be
correct in thinking that it doesn’t really make much sense to go through the bother of
creating a class just to call rect(), which you could call from within setup(). This is certainly
true. So let’s add some stuff to make all this class business worth it. Let’s build a
simple house, with a door, some windows, and a roof, and then let’s put a couple houses
together to form a little neighborhood. I’m going to make a class for each of the following
elements: door, window, roof, and house. In this example, I’ll keep things simple by not
adding decorative features like paint, shingles, cornices, and so on. And I’ll keep all the
classes within the same PDE file (which isn’t really necessary). Later in the book, I’ll show
you how to begin working with multiple files in separate Processing tabs.
