Description

You are to write a class called MovieCollection following the diagram below.  You may use your Movie class you wrote in lab, but notice a few small changes have been made.  A few methods have been removed, and a few have been added.  Also the format it prints out in is slightly different as well.

MovieCollection

– movies: Movie[

– movieCount: int

+ MovieCollection()

+ getTotalMovies(): int

+ addMovie(movie, Movie): boolean

+ addMovieAt(movie,Movie: index, int): boolean

– shiftCollectionRight(index, int)

+ findMovie(movie, Movie): int

+ getMovieAt(index, int): Movie

+ removeMovie(movie, Movie): boolean

+ removeMovieAt(index, int): Movie

– shiftCollectionLeft(index, int)

+ findBestMovie(): Movie

+ nnoviesToAvoid()

+ moviesToWatch()

+ printOutMovieList()

Movie

– name : String

– minutes : int

– tomatoScore : int

+ Movie {name: String, minutes: int, tomatoScore :int)

+ getName(): String

+ getMinutes(): int

+ getTomatoScore(): int

+ setTomatoScore(score: int)

+ isFresh(): boolean

+ toString(): String

+ equals(other: Object): boolean

 

Requirements

Your Movie objects are stored in an array in the MovieCollection class. For this assignment, you are only allowed to hold 10 movies at a time, even though in real life you may own many more. Another instance variable you have to manage is the movieCount variable. The movieCount variable is meant to tell how many movies you currently have, and where the next movie is to be added if it can. The

movieCount variable may only increment or decrement by one when necessary.  Also, no null elements are allowed between the start of the array to movieCount, ie no empty movie slots.

The movies do not need to be sorted. They are simply added to where movieCount is currently pointing or where specified by addMovieAt(int index).  If you have 10 movies, it should not add any more movies unless you remove a movie.

In the assignment description I have added many comments above each method to give further descriptions.

 

I have provided Junit testing for most methods and a simple driver you may use to test your code. Below is a sample out.

 

One last comment about the Movie class from lab, it may not have been as obvious from seeing the code below, but toString() converts the minutes to hours and minutes.  For example, 125 converts to

2hrs 5min.  You may add a private helper method to do the conversion if you wish.

 

Grad Students

You will add more test cases to the removeMovieAt method. I have not done extensive testing on this method, so you are responsible for providing further testing on it. Think of what values could make a test fail and test for false results.  Or simply add a random set of method calls to shift things around and ensure removeMovieAt returns the correct values.
