    Default Need help with my hangman program!

    Hey guys,
    I have to make a Hangman game in Java that asks the user to input their name when you run the program.
    The name is saved to a .txt file that records the WINS and LOSSES for the game.
    There is supposed to be another .txt file that has the words to be used for the game.

    Here is what I have so far:
    PHP Code:
    import java.util.Scanner;
    import java.util.Random;
    import java.io.*;

    public class 
    Hangman {

    Scanner in = new Scanner(System.in);
    String puzzle;
    String puzzleWord;
    int puzzleIndex;
    Random generator = new Random();
    boolean win;
    boolean over;
    String correct ""
    char guesses[] = new char[26];
    int guessed;
    int misses;
    int again;
    String puzzles[] = new String[4];
        public static 
    void main(String[] args) {
    String letter;
    String again "y";
    Hangman game = new Hangman();
    BufferedReader in =
    BufferedReader(new FileReader("C:\\Users\\Michael\\My Documents\\puzzles.txt"));
    int count 0;
                while (
    game.puzzles[count] = in.readLine();
    IOException e)
    System.out.println("Error during reading/writing");
    System.out.println ("Welcome to Hangman!");
    again.equals ("y"))
    System.out.println("Puzzle: " game.puzzle);
    System.out.println("Enter a letter: ");
    letter game.in.next();
    game.guesses[game.guessed] = letter.charAt(0);
    game.puzzleWord.indexOf(letter.charAt(0)) != -1)
    game.correct game.correct letter.charAt(0);
    game.puzzle game.puzzleWord.replaceAll("[^"+game.correct+" ]","-");
    game.puzzleWord.replaceAll("["+game.correct+" ]","").length() == 0)
    game.win true;
    game.over true;
    System.out.println("Solution: " +game.puzzleWord);
    System.out.println("You've won the game!");
    String again(){
    String again;
    System.out.println("Would you like to play again? (Y/N)");
    again in.next();
    again.charAt(0) == 'Y')
    the game.printBoard(), game.printGuesses(), game.init(), game.miss() methods are not defined. and I am not too sure what that means. Can anyone help me rewrite that part of the program? I also have not been able to write the code to save a .txt file to record the WINS and LOSSES. And I believe the If else statement at the end that asks you if you want to play again is wrong.

    Default Re: Need help with my hangman program!

    private Scanner in = new Scanner(System.in);

    private String puzzle;
    private String puzzleWord;
    private int puzzleIndex;
    private Random generator = new Random();
    private boolean win;
    private boolean over;
    private String correct = "";
    private char guesses[] = new char[26];
    private int guessed;
    private int misses;
    private int again;
    private String puzzles[] = new String[4];
    This is all the code you use to define your Hangman object; the methods printBoard(), printGuesses(), init(), and miss() are not defined because you haven't defined them. Nowhere in your code do you state something like:

    public void printBoard()

    yet in your main method you make calls to the the printBoard() method as if it exists -- but you haven't made it yet! The program can't read your mind -- if you want it to print the board, you have to explicitly code what that means.

                    System.out.println("You've won the game!");
                    String again(){
                        String again;
                        System.out.println("Would you like to play again? (Y/N)");
                        again = in.next();
                        if(again.charAt(0) == 'Y')
                            return "Yes";
                            return "No";

    Why do you have return statements here? Firstly, the main method almost never returns anything (in fact, it is bad coding to have it return something). Secondly, even if returning values from the main method was okay, you have its return type as void -- meaning it can't return anything!

    As for writing characters to a text file, I suggest a FileWriter.
