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

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

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]
