im trying to read one letter form a data file and it gives me the error at "alpha.read (char lettersguessed [x], 0, 25);" [code]// The "Guessing" class. import java.awt.*; import hsa.Console; import java.io.*; public class Guessing { static Console c; // The output console public static void main (String [] args) throws IOException { c = new Console (); // declares variables and data files BufferedReader input = new BufferedReader (new FileReader ("word.txt")); int sets = 1, ran, many, wrong = 0, fcount = 0, temp2, choice = 0, tried = 0; String words [], temp, word; char gword, no = 'n', yes = 'y', fword [], guessed [], lettersguessed []; words = new String [sets]; for (int x = 0 ; x < sets ; x++) { words [x] = input.readLine (); } input.close (); do { // selects a random word and finds its length and creates arrays ran = (int) (Math.random () * sets); word = words [ran]; many = word.length (); fword = new char [many]; guessed = new char [26]; lettersguessed = new char [26]; c.println ("What would you like to do? 1.
