Type mismatch: cannot convert from void to String

I am getting the error on String guessAsString

public boolean promptForGuess() {
        String guessAsString = System.out.println("Enter a letter:   ");
        char guess = guessAsString.charAt(0);
        return mGame.applyGuess(guess);
    }

System.out.println("Enter a letter:   ");

This is printing a line, not prompting for a string. That is why it won't return anything, instead of returning a String.

You need to get the console to read the input on the line from the user. Your current code just prints out a line on the console. So what do you think you need to put to get the console to read some input?

That's because the code you posted is wrong. You should get errors anywhere you run the code you posted because it's not right. Try this:

public boolean promptForGuess() {
        String guessAsString = System.out.readLine("Enter a letter:   ");
        char guess = guessAsString.charAt(0);
        return mGame.applyGuess(guess);
    }
