    [RESOLVED] Need help with hangman program java

    Code:
    import java.util.Scanner;//imports a Scanner Class
    import java.util.Random;//imports a Randomizer
    
    public class HangmanMy {
      public static void main (String[] args){
        System.out.println("\t\t\t\t\t************Welcome to Hangman*************");//Intro to the game
        Scanner input = new Scanner(System.in);//Instalizes a new Scanner called input 
        boolean done = false;//new boolean variable done that is set to false
        boolean reset = true;//new boolean variable reset that is set to true
        String guess;//new String Variable guess
        String guesses = "";
        char letter;//new char variable
        int wrongGuess = 6;//new interger variable wrongGuess that stores the value 6 in it, which is the max wrongGuess the user can have
        StringBuffer dashes;//new StringBuffer variable dashes
        while(reset == true){
          System.out.println("Choose a category -> places / games / animals / subjects ");//Asks the user what types of word they want
          String words = wordsToChoose(input.nextLine());//creates a new String and itand chooses the word from the method wordsToChoose from the answer given
          dashes = makeDashes(words);//makes dashes for each of the letter in the word
          done = false;
          while(done == false){//when done is false, it does this
            System.out.println("Here is your word: " + dashes);//prints out the word in dashes 
            System.out.println("Guesses so far: " + guesses);//the guessess the user made so far
            System.out.print("enter a guess (letter or word): ");//this asks the user to enter a guess
            guess = input.next();//takes the answer
            // process the guess
            
            if (guess.length() > 1)//if the length of the answer was more than 1 letter it will do this:
            {
              if (guess.equalsIgnoreCase(words))//if the guess was the word
                System.out.println("You got it, Good Job!!");//it prints out this on the screen and the games ends
              else //if it dosen't match the word
                System.out.println("Thats not the word, the word was: " + words);//it prints out this on the screen and the games ends
              done=true;//now done is true so the loop will stop
            }
            else // if the user only puts a letter it will process a single letter guess
            {
              letter = guess.charAt(0);
              guesses += letter;
              if (words.indexOf(letter) < 0)  //if the letter given is not in the word it will do this:
              {
                wrongGuess--;//this takes out 1 wrongGuess from six everytime the user gets the letter wrong
                if((wrongGuess <= 5)&&(wrongGuess >= 1)){
                  System.out.println("Guesses left: " + wrongGuess);}//prints out this when the wrongGuess are between 5-1
                else if(wrongGuess == 0){//when the wrongGuess becomes 0
                  System.out.println("Not Bad! Unfortunately you're all out of guesses. My word was " + words);// prints out the real word cause there were too many guesses

    Re: Need help with hangman program java

    Hello fellow Java user This is what i came up with while studying your code.

    by using the break(); command you only disable the current loop , be it a while loop, a for loop, or a do while loop. now the problem with your code is as it follows:

    Code:
     while(done == true)
            {
              System.out.println("\nDo you want to play again?");
              String answer = input.next();
              
              if(answer.equalsIgnoreCase("no")){
                System.out.println("GOOD-BYE, THANKS FOR PLAYING"); break;}
              if(answer.equalsIgnoreCase("yes")){
                reset = true; break;}
            }
    by using the command break(); in the following line:
    Code:
    if(answer.equalsIgnoreCase("no")){
                System.out.println("GOOD-BYE, THANKS FOR PLAYING"); break;
    you basically just break out from the while(done==true) loop, but being given the fact that reset is still true, the main loop has no reason to stop. What i would do is the following. Replace the faulty line with this:

    if(answer.equalsIgnoreCase("no")){
    System.out.println("GOOD-BYE, THANKS FOR PLAYING"); reset = false; break;



    I haven't seen you do this in your code, so basically you don't break the main loop's condition (while(reset == true)), so it has no reason to stop.


    some ground notes.

    While using loops and methods with booleans (true/false) you dont need to actually write the code like this
    while(boolean == true) or while(boolean == false)

    It is considered good programming to do the following

    while(boolean)/*this means the boolean is true*/ or while(!boolean) /*this mean that the boolean is false*/ (Thanks keang for sharing this a long while ago)


    well, i hope it helps
