Thread: 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
