    Default Read a char for a category

    i need to allow the user to input a single char instead of the whole word without changing the public class MovieIO,


    import java.util.ArrayList;
    import java.util.Scanner;
     
    public class MovieListApp	{
     
        static Scanner sc = new Scanner(System.in);
     
            System.out.println("  Welcome to the Movie List Application!\n");
     
            ArrayList<Movie> movies = getMovies();      // fills the array list
     
            System.out.println("  There are " + movies.size() + " movies in the list.");
     
            String category;       // used to search for films of a specific category
     
            do	      {
                category = getString("  What category are you interested in? (or (X) to Exit)\n  (A)nimated    (C)omendy   D(o)cumentary\n  (D)rama       (H)orror     (M)usical\n  (S)ciFI\n Enter Your Selection ->  ");
     
     
     
                for (Movie m : movies)
                {
                    if (m.category.equalsIgnoreCase(category))
                        System.out.println(m.title);
                }
                System.out.println();
            } while (!category.equalsIgnoreCase("X"));
            System.out.println("\n  Program terminated  ");
     
        }
     
        public static ArrayList<Movie> getMovies()	    {
            Movie m;
            ArrayList<Movie> movies = new ArrayList<Movie>();
            for (int i = 1; i <= 102; i++)
            {
                m = MovieIO.getMovie(i);
                movies.add(m);
            }
            return movies;
        }
     
        public static String getString(String prompt)	   {
            String s = "";
            boolean isValid = false;
     
            while (!isValid)         // loops until user enters a non-blank line
            {
                System.out.print(prompt);
                s = sc.nextLine();
                if (!s.equals(""))
                    isValid = true;
            }
            return s;
        }
     
    }

    public class Movie	{
    	public String title;
    	public String category;
     
    	public Movie(String title, String category)	{
    		this.title = title;
    		this.category = category;
    	}	// end CONSTRUCTOR
     
    }	// end Movie CLASS

    public class MovieIO	{
        public static Movie getMovie(int index)	    {
            switch (index)	{
                case 1:
                    return new Movie("Citizen Kane", "drama");
                case 2:
                    return new Movie("Casablanca", "drama");
                case 3:
                    return new Movie("The Godfather", "drama");
                default:
                    return new Movie("NO SUCH MOVIE", "");
            }	// end SWITCH
        }	// end getMovie METHOD
    }	// end MovieIO CLASS
