In the second part of your project, you are to write a Movie Application that stores a library of movies and implements several functionalities, such as printing all movies in the library.

We provide the following files here: http://www.research.cs.rutgers.edu/~anapaula/cs111/cs111MovieApp.zip:

IO.java: the IO class

Movie.java: the Movie class from the first part of the project

MovieApp.java: the application file you are to update and submit

MovieDriver.java: a driver to test your MovieApp

MovieApp.java contains all the methods you need to implement. Refer to the methods description on file for your implementation. Fill in the code in the methods MovieApp, addMovie, removeMovie, getMovies, getNumberOfItems, updateRating, print, getMovieByDirector, getMovieByYear, and getMoviesWithRatingsGreaterThan.

Submit the file MovieApp.java

Observe the following rules:

DO NOT add any import statements to MovieApp.java

DO NOT change the headers of ANY of the given methods

DO NOT change/remove any of the given class fields

DO NOT add any new class fields

DO NOT use System.exit()

DO NOT use the IO module in MovieApp.java

YOU MAY add new helper methods, but you must declare them private

If you wish to change MovieDriver, feel free. You are not submitting it.

This is the code I have but when I tried to compile I got this error message:

MovieApp.java:55: error: cannot find symbol

System.out.println(items[i]);

^

symbol: variable i

location: class MovieApp

1 error

I don't see what I did wrong. Please help me fix this!!
