Write Java Code for:
Add a new class, LibraryCollection. This class will have --
a private instance variable that contains a collection of all your books
a private instance variable that contains a collection of all of your movies
a constructor that calls private methods to initialize your books and movies collection
a method to add a book to your books collection
a method to add a movie to your movies collection
a method to remove a book from your books collection

a similar method to search for movies.
Finally, you need to write a class that can do the following by asking a user to enter data through the Blue J terminal window. You can invoke a method on this class to get started -- for example you might have a method public void returnABook() – that will ask you to enter the reference number of the book to be returned, then update the book’s status in your collection. In addition, this class should be able to do the following --
