Thread: String to Array?

OK so I actually have a couple basic problem but the most important problem is the array. I am making a hangman game. I have a driver that was supplied but it is actually confusing me more.

1. Does the driver get the information from the file for me, or do I need to have the code that I put in main to get the information?

2. I tried to output the String word just so that I knew file.next was working to get the information from the file, but I couldn't get it to output from either the displayGameIntro or play methods because it didn't recognize the variable. Any suggestions?

3. This has to do with #2, since I can't seem to get the String word to be recognized, I can't turn it into an array. My plan is to create an array called letter (which I commented out while i was trying to get the other stuff working) that I can use when I am checking to see if the user has entered the correct letter. Is this the wrong idea to be using. Should I not use an array to check if the guessed letter is correct?

Here is the driver:

/* This program is a word guessing game called hangman.
 * A person will try and guess a word before the max 
 * number of guesses are used. Every time the user chooses an 
 * incorrect letter another body part is displayed in the gallows.

import java.util.*;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
 
public class HangmanDriver {
 
    public static final String filename = "hw7data.txt";
 
    // Driver to run the game using the student Hangman class
    public static void main(String[] args) {
        Scanner wordsFile = null;                  // words data file
 
        // open the file containing the words
        try {
            wordsFile = new Scanner(new FileInputStream(filename));
        }
        catch (FileNotFoundException e) {
            System.out.println("File not found or not opened.");
            System.exit(0);
        }
 
        // create object and prepare to play game
        Hangman game = new Hangman(wordsFile);
        Scanner keyboard = new Scanner(System.in);
 
        // display an introduction on the game to the player
        game.displayGameIntro();
 
        // continually play new games if the user desires
        String playAgain;
        do {
            game.play();
            System.out.print("Do you want to play again? ");
            playAgain = keyboard.next();
            System.out.println();
        } while (playAgain.toUpperCase().startsWith("Y"));
 
        System.out.println("Thanks for playing!");
    }
}

This is my program:

// This program runs a game of hangman
// The point is to guess the word based on the number of blank spaces

        System.out.println("The blank spots indicate how long the word is. Each");
        System.out.println("correct letter will show up in the correct spot, while");
        System.out.println("a wrong guess will lead to another body part being");
        System.out.println("displayed. After seven incorrect guesses, you lose.");
 
    }
 
    public void play () {
        // Here is some high-level pseudocode of what you want to do:
        //
        // Initialize everything, such as arrays
        //int [] letters = new int [word.length];
        //for loop that takes word into array letters
        //for(int i = 0; i < word.length; i++){
        //    letters [i] = word[i];
        //
 
        // Get one word from the data file
        // Loop until game is over:
        //		Display current picture, letters guessed, wrong guesses, and word so far
        //		Get a valid, not-yet-guessed letter from the player
        //		Determine if the letter is in the word and update variables appropriately
        // Handle winning or losing
 
 
    }
 
}

What happens when you execute the code?

What does the driver code pass to the Hangman constructor?

I couldn't get it to output

Is the method called? If it is called it should print out some messages. Do any of its messages get printed?
