00:03

And here's your shmoop du jour brought to you by a bunch of

00:06

hooligans who crashed the boat party they just barged in...consider the [People partying on a boat]

00:11

following class declaration........

00:16

which of the following is not part of an effective application of functional

00:21

decomposition....... alright here we go well the idea of functional

00:29

decomposition is to simplify our class by creating a hierarchy of sub classes [Sub classes appear out of a box]

00:34

containing data fields and methods relevant to that specific class well in

00:39

this case boat should become a superclass with only data fields and [Boat sinks in the ocean]

00:43

methods that are universal for all types of boats

00:45

Choice A does this exactly simplifying boat so that it is a superclass for

00:51

other classes choice B also gets us one step closer to [Man moves up a step]

00:55

functional decomposition by removing data fields that should be in its

00:59

subclass. Choice C doesn't look quite right we want all boats to be named because [Boats in the harbour with names]

01:05

this is a property on all boats, we should declare it in the parent class boat but

01:10

let's come back to this in a sec. Choice D also helps with functional decomposition

01:15

we want one generic print function in the boat class but every subclass should

01:20

override it to customize it to the specific boat type finally choice E

01:24

describes one of the most basic actions to achieving decomposition each subclass [Sub classes sitting at their desks]

01:30

should have data fields and methods that are specific to it so that just leaves

01:34

our correct answer as C, next time learn about the admiral who was against

01:39

buying a new hat he was afraid of capsizing [Admiral falls overboard]
