Initialization can be done in instance-method initializors that are
incorporated into the new
class method. For example, suppose that
you want the initial value of each Food
instance variable to be
0
, rather than nil
. You first define an initializor instance
method that sets values to 0
:
Food method definition instance initialize self fCalories: 0; cCalories: 0; pCalories: 0.
Next, you incorporate the initialize
instance method into the
new
class method:
Food method definition class new ^ super new initialize
Then, all new Food
instances have instance variables set to 0
