title: Expand array once it reaches limit
body: <p>I have a program in which I need to print out several <code>Movie</code> objects (represented just by a single String) in an array. I start with a text file that already has five movies inside of it, but in the console, I am to allow the user to expand the array if he/she wants. (I cannot use an arraylist in this problem). I've attempted to design a program that does this, but I get an out of bounds exception each time I try to add a new movie. I also need to check the array to see if there is a duplicate movie object inside it? How can I do that? </p>
  
  <p><strong>Question: How can I allow the user to expand the array and add more movies to the list? How can I check the array to see if there is already a certain movie title inside of it?</strong> </p>
