    Question For Loop and String Problem - Console Hangman Game

    I am doing my Hangman Project and need assistance. I am doing the first part, have managed to hide the word using , but now the problem I am facing is. After I first guess I need it to replace with appropriate letter. But with the code below here is my output. The word in this example is "hello"

    Welcome to Hangman... v1.0 - Designed Ashley Bwanya
    This is the word you have to guess:

    * * * * *

    Enter your first guess
    h
    h* *

    import java.util.Scanner;
    public class Hangman
    {
    public static void main(String[] args)
    {
    int attempts = 6;
    String secret;
    String displaySecret = "";

    Scanner scn=new Scanner(System.in);

    Game myWord = new Game();

    secret = myWord.getWord();

    for (int i = 0; i < secret.length(); i++)
    {
    displaySecret += " * ";
    }
    System.out.println("Welcome to Hangman... v1.0 - Designed Ashley Bwanya");
    System.out.println("This is the word you have to guess: \n");
    System.out.println(displaySecret+ "\n");

    System.out.println("Enter your first guess");
    char firstGuess = scn.nextLine().charAt(0);

    int position = secret.indexOf(firstGuess);

    String newDisplaySecret = "";

    for (int i = 0; i < secret.length(); i++)
    if (i == position)
    newDisplaySecret += secret.charAt(i); //newly guessed character
    else
    newDisplaySecret += displaySecret.charAt(i); //old state

    displaySecret = new String(newDisplaySecret);

    System.out.println(newDisplaySecret);

    }
    }

    Default Re: For Loop and String Problem - Console Hangman Game

    I don't want to ruin the challenge for you but if you would like you can take a look at my java hangman example... Java Hangman! however keep in mind that I am a beginner here as well but I did manage to get that part of my program to work just fine using a StringBuilder. This allowed me to modify a string where as a String is immutable.

    String word = "";
    for(int i = 0; i < secret.length(); i++){ // display dashes for length of word
    word += "-";
    }
    StringBuilder guessedWord = new StringBuilder(word);
    System.out.println(guessedWord); // print number of dashes for word
    for(int i = 0; i < guessedWord.length(); i++){ // check for letter in word
    if(guess == secret.charAt(i)){
    guessedWord.setCharAt(i, guess);
    }
    }//end for
