Hi. I can't get the code to work in the console.
First, Hangman.java:
public class Hangman {
public static void main(String[] args) {
// Enter amazing code here:
Game game = new Game("treehouse");
Prompter prompter = new Prompter(game);
prompter.displayProgress();
boolean isHit = prompter.promptForGuess();
if (isHit) {
System.out.println("We scored a hit!");
} else {
System.out.println("Missed!");
}
prompter.displayProgress();
}
}
Game.java:
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;
}
public String getCurrentProgress() {
String progress="";
for (char letter: mAnswer.toCharArray()) {
char display = '-';
if (mHits.indexOf(letter) >= 0) {
display = letter;
}
progress += display;
}
return progress;
}
}
Prompter.java:
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 void displayProgress() {
System.out.printf("Try to solve: %s\n", mGame.getCurrentProgress());
}
}
In the console I typed: java-repl. Then: clear && javac Hangman.java && java Hangman. The program wouldn't run. Here's what I got:
ERROR: not a statement
clear && javac Hangman.java && java Hangman;
^
ERROR: ';' expected
clear && javac Hangman.java && java Hangman;

I'd appreciate any help.

33,235 PointsHi. Thanks for trying to help.
I've just got home from work. I typed in, without using the repl:
clear && javac hangman.java && java hangman
This time I got this message:
use -help for a list of possible options
Have I done this right?
