Assignment 3 – Theatre Solution
This is the most complex application that you have seen so far. It is comprised of six user defined types: four classes and two enums. This assignment attempts to simulate a simple version of a Theater application. In this application the user is able to search for a movie based on genre, name of actor, the time of the day and the day of the week.
You should define your types in the following order: the two enums, Time, Movie, Show and then Theater You will perform some simple queries on this collection.
The MovieDay Enum
This type represents the days of the week and is comprised of seven constants. The constants are the first three letters of the day of the week.
The MovieGenre Enum
This type represents the various categories of movie. Because a movie may fall under multiple categories, you will have to use the [Flags] to decorate this enum.
The bit-wise operator is used to combine more than one genre. E.g. MovieGenre genre = MovieGenre.Action | MovieGenre.Romance | MovieGenre.Comedy;
For this to work correctly, you will have to assign appropriate values for each name. Appropriate values are 0, 1, 2, 4, 8, 16, 32 etc.
The Time Class
This type represents the days of the week.
Time
Class
Properties
+ Hours {get; set;} : int
+ Minutes {get; set;}: int
+ Seconds {get; set;}: int
Methods
+ Time(hours : int, minutes : int, seconds : int)
+ ToString() : string
Properties:
All of the properties have public getters and private setters and are self-explanatory.
Hours – this property is an int representing the hour. The getter is public and the setter is private.
Minutes – this property is an int representing the minute. The getter is public and the setter is private.
Seconds – this property is an int representing the second. The getter is public and the setter is private.
Methods:
Time(int hours, int minutes, int seconds) – This public constructor takes three int parameters and assigns them to the appropriate properties
ToString() – This method overrides the same method of the Object class. It does not take any parameter but return a string representation of itself. You decide on the format for the output.
The Movie Class
This class will model a movie.
Movie
Class
Properties
+ Length {get; set;} : int
+ Title {get; set;}: string
+ Genre {get; set;}: MovieGenre
+ Cast {get; set;}: List<string
Methods
+ Movie(title : string, length : int)
+ AddActor(actor : string) : void
+ SetGenre(genre : MovieGenre) : void
+ ToString() : string
Properties:
All of the properties have public getters and private setters and are self-explanatory.
Length – this property is an int representing the length of the movie in minutes. The getter is public and the setter is private.
Title – this property is a string representing the title of the movie. The getter is public and the setter is private.
Genre – this property is an enum representing the genre of this movie. The getter is public and the setter is private.
Cast – this property is a list of string representing the names of the actors in this movie. The getter is public and the setter is private.
Methods:
Movie(string name, int length) – This public constructor takes one string and one int It does the following:
Assigns the arguments to the appropriate properties.
Initialize the Cast property to
AddActor(string actor) – This public method takes a single a string argument and adds it to the collection of actors (Cast).
SetGenre(MovieGenre genre) – This public method takes a single enum argument and assigns it to the property of the same name.
ToString() – This method overrides the same method of the Object class. It does not take any parameter but return a string representation of itself. You will need to build a single string comprising all of the actors in this movie. You decide on the format for the output.
The Show Class
This class models a movie show. You will also implement this in Visual Studio. A short description of the class members is given below:
Show
Class
Properties
+ Price {get; set;} : double
+ Day {get; set;} : MovieDay
+ Movie {get; set;} : Movie
+ Time {get; set;} : Time
Methods

+ ToString() : string
Properties:
Price – this property is a double representing the price of admission to this show. The getter is public and the setter is private.
Day – this property is an enum representing the day of the week of this show. The getter is public and the setter is private.
Movie – this property is an object reference of the movie class. The getter is public and the setter is private.
Time – this property is an object of the Time class representing the time of this show. The getter is public and the setter is private.
Methods:
Show(Movie movie, MovieDay day, double price, Time time) – This is the public constructor that takes four arguments and assigns them to the appropriate properties.
ToString() – This is the public method overrides the method of the same name in the object class to return a meaningful description of this object.

Assigns the argument to the property.
Initialize the Shows property to a new list of show
Again, this is a good example of method overloading
AddShow(Show show) – This public method takes a show object and adds it to the collection of shows.
PrintShows() – This public method does not take any argument neither does it return a value. It displays all the shows that is available.
PrintShows(MovieGenre genre) – This public method takes a genre as an argument and display all the shows that contains the flag of this genre.
