Help me write a java code.
Movie.java:
MovieApp.java:
MovieDriver.java:
the second part of your project, you are to write a Movie Appl as printing all movies in the library We provide the following files here In ication that stores a library of movies and implements several functionalities, such 1 1O java: the IO class 2 Moviejava the Movie class from the first part of the project 3 MovieApp java: the application file you are to update and submit 4 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. Fil in the code in the methods MovieApo addluMovie temovelovie getlovies getNumberofitems vadateRating aziat, getovieByDirector getMovießvyear and print Submit the file MovieApp.java rve the following rules DO NOT add any import statements to MovieAppjava DO NOT change the headers of ANY of the given methods DO NOT change/remove any of the given class fielads DO NOT add any new class felds DO NOT use System.exite You MAY add new helper methods, but you must deciare them private you wish to change MovieDriver. feel free You are not submitting tExplanation / Answer
Please find the below code for MovieApp.java.
I have implemented all the methods and tested using the driver class. Please free to comment back if you have any clarifications. The code for all other classes remains same.
