here's my Prompter.java code:

import java.io.Console;

public class Prompter {
  private Game mGame;

  public Prompter(Game game) {
    mGame = game;
}

  public void play() {
    while (mGame.getRemainingTries()>0) {
      displayProgress();
      promptForGuess();
    }
  }

public boolean promptForGuess() {
  Console console = System.console();
  boolean isHit = false;
  boolean isValidGuess = false;
  while (! isValidGuess) {
    String guessAsString = console.readLine("Enter a letter  ");
    char guess = guessAsString.charAt(0);
    try {
      isHit = mGame.applyGuess(guess);
      isValidGuess = true;
    } catch (IllegalArgumentException iae) {
       console.printf("%s. Please try again.\n", iae.getMessage());
    }
    return isHit;
  }

public void displayProgress() {
  System.out.printf("You have %d tries left to solve: %s\n",
                    mGame.getRemainingTries();
                    mGame.getCurrentProgress());
    }
  }
}

You're missing an end curly brace in this method for the while loop (comments added):

public boolean promptForGuess() { // <-begin method
  Console console = System.console();
  boolean isHit = false;
  boolean isValidGuess = false;
  while (! isValidGuess) { // <-begin while
    String guessAsString = console.readLine("Enter a letter  ");
    char guess = guessAsString.charAt(0);
    try { // <-begin try
      isHit = mGame.applyGuess(guess);
      isValidGuess = true;
    } catch (IllegalArgumentException iae) { // <-end try and begin catch
       console.printf("%s. Please try again.\n", iae.getMessage());
    } // <-end catch
    return isHit;
  } // compiler sees this as the end of the while loop but looks like it should end the method.
