Java

Cannot compile Prompter.java

Prompter.java will not compile in the hangman program section of the Java course after I added the code to determine if the game was won or not.

import java.io.Console;

public class Prompter {
  private Game mGame;

  public Prompter(Game game) {
    mGame = game;

  }

  public void play() {
    while (mGame.getRemainingTries() > 0 && !mGame.isSolved()) {
      displayProgress();
      promptForGuess();
  }
    if (mGame.isSolved()) {
      system.out.printf("Congratulations, you won with %d tries remaining. The answer was %s.", mGame.getRemainingTries(), mGame.getAnswer());
    } else {
      System.out.print("Bummer, the word was %s.", mGame.getAnswer());
  }
  }

  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;
  }

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

The console is printing out:

Prompter.java:17: error: package system does not exist
system.out.printf("Congratulations, you won with %d tries remaining. The answer w as %s.", mGame.getRemainingTries(), mGame.getAnswer());
^

Try these fixes out:

Line 17

//system -> System
System.out.printf("Congratulations, you won with %d tries remaining. The answer was %s.", mGame.getRemainingTries(), mGame.getAnswer());

Line 19

// print -> printf
System.out.printf("Bummer, the word was %s.", mGame.getAnswer());

Worked. Thanks!
