it says my message is not simplified enough and my guessAsString is not correct

public boolean promptForGuess() {
    Console console = System.console();
    boolean isHit = false;
    boolean isValidGuess = false;
   while (! isValidGuess) {
    String guessAsString = console.readLine("Enter a letter:  ");

     try {
       isHit = mGame.applyGuess(guessAsString);
     isValidGuess = true;
     } catch (IllegalArgumentException iae) {
      console.printf("%s. Please try again.\n", iae.getMessage()); 
     }

   }
    return isHit;

error message:

public boolean promptForGuess() {
    Console console = System.console();

     try {
       isHit = mGame.applyGuess(guessAsString);
     isValidGuess = true;
     } catch (IllegalArgumentException iae) {
      console.printf("%s. Please try again.\n", iae.getMessage()); 
     }

   }
    return isHit;

String guessAsString = console.readLine("Enter a letter:  ");

     try {
       isHit = mGame.applyGuess(guessAsString);

The applyGuess() method only accepts a single char. This is trying to send in a String. You will need to trim down the String to just the first char of the String.

String guessAsChar = guessAsString.charAt(0);

try {
       isHit = mGame.applyGuess(guessAsChar);
