non-static method promptForGuess() cannot be referenced from a static context

I got this message while compiling: Hangman- java7; non-static method promptForGuess() cannot be referenced from a static context

A Prompt instance should have been made. I don't see what I'm doing wrong.

This is my code: public class Hangman {

public static void main(String[] args) {
    // Enter amazing code here:
  Game game = new Game ("Threehouse");
  Prompter prompter = new Prompter (game);
  boolean isHit = Prompter.promptForGuess();
  if (isHit){
  System.out.println("We got a hit!");
  } else{
    System.out.println("Whoops that was a miss");
}

}

}

import java.io.Console;

public class Prompter { private Game mGame;

public Prompter (Game game){
mGame=game;

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

}

public class Game { private String mAnswer; private String mHits; private String mMisses;

public Game(String answer){ mAnswer = answer; mHits = ""; mMisses=""; } public boolean applyGuess(char letter){ boolean isHit= mAnswer.indexOf(letter)>=0;

if (isHit){
  mHits += letter;   

} else { mMisses += letter; } return isHit; } }

Please, help! Thanks. Regard, Rik-Jan
