Remember back in chapter two I said this:

In Java, a blueprint is called a class. When a class is transformed into a real working thing, we call it an object or an instance of the class.

The first step is to turn the classes(blueprints) we need into real working things, objects/instances. This step is analogous to declaring variables.

First, we state the type, which in this case happens to be a class and then we state the name we would like our working object to have.

// Here are all the objects(instances)
// of classes that we need to do some drawing
ImageView myImageView;
Bitmap myBlankBitmap;
Canvas myCanvas;
Paint myPaint;

The previous code declares reference type variables of types ImageView, Bitmap, Canvas, and Paint. They are named myImageView, myBlankBitmap, myCanvas, and myPaint, respectively.
