When you create a RabbitApplication instance, you need to initialize
that instance such that the value of the rabbits variable is a
SortedCollection instance that is sorted according to the delivery
months of the rabbits. The rabbit with the earliest delivery month will
always be at the front:
RabbitApplication method definition • instance initialize rabbits := SortedCollection sortBlock: [:x :y | x deliveryMonth < y deliveryMonth]. rabbits add: (Rabbit new deliveryMonth: 2)
Note that initialize inserts exactly one Rabbit instance,
born at month 0, into the sorted collection assigned to the
rabbits instance variable.
