## Nested Classes (#4)
|
|
|
|
|
|
|
|
|
|
Improve the implementation of the *State* pattern in `Ticket.kt`. Change `Seat`
|

|
|
|
from an enumeration to a non-nested `abstract class`, with a nested subclass for
|
|
|
|
|
each `Seat` type. `Seat` contains `abstract` member functions for `upgrade()`
|
|
|
|
|
and `meal()`. There's also a `toString()` for `Seat` that produces the
|
|
|
|
|
`simpleName` of the specific subclass.

|
|
|
`Ticket` now becomes a simple holder for a `Seat` object, along with `upgrade()`
|
|
|
|
|
and `meal()` functions which forward their actions to the `Seat` object.

Bonus (Challenging): Why can't you use delegation for `seat` in `Ticket`?
