Thread: Hangman

I'm having a problem with this code, specifically at the "if (guess.indexOf(letter) >= 0))" part, where I get the error: "The method indexOf(String) in the type StringBuilder is not applicable for the arguments (char)"

I highlight for suggestions and it just creates a loop, so it's just frustrating.

The other thing, I seem to have a problem doing (and always have for some reason), is that I know a do/while part would help, but I keep putting it in different places, but not working. Any suggestions? I'm not wanting direct answers, but some hints would be helpful.

 import java.util.Scanner;
 
public class HangmanClass {
 
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		String [] words= {"write", "that", "program", "fusion"};
 
		Scanner input= new Scanner(System.in);
		char newGame;
 
		{
		int index= (int)(Math.random() * words.length);
 
		String word= words[index];
		StringBuilder guess= new StringBuilder();
 
		for (int i=0; i < word.length(); i++){
			guess.append('*');
		}
		int CorrectGuesses=0;
		int Misses=0;
 
		while (CorrectGuesses < word.length()){
			System.out.println("(Guess) Enter a letter in word " +guess+ " > ");
			String s= input.nextLine();
			char letter= s.charAt(0);
 
		if (guess.indexOf(letter) >= 0){
			System.out.println("\t" +letter+ " is already in the word");}
		else if (word.indexOf(letter) < 0) {
			System.out.println("\t" +letter+ " is not in the word");
			Misses++;}
		else {
			int h= word.indexOf(letter);
			while (h >= 0) {
				guess.setCharAt(h, letter);
				CorrectGuesses++;
				h= word.indexOf(letter, h+1);
 
				}		
			}
		}
		System.out.println("The word is " +word+ ". You missed " +Misses+ " time(s).");
 
		System.out.println("Do you want to guess another word? Enter y or n>");	
	}
 
	}
}

Yes, StringBuilder.indexOf() expects a String argument. You can use that method as it requires, or you could use a String method that might be more to your liking after changing the StringBuilder object to a String, of course.

Explain what you want the do/while loop to do, show what you've tried with any errors, and ask questions about that code.

I'm wanting for the do part to do the hangman game while the user wants to continue playing.

So you do something like:

do
{
    while ( puzzleNotSolved )
    {
        // the user plays a game of hangman
    }
 
    // ask the user if another game is desired
 
}
while ( userWantsAnotherGame );

Alrighty, I'll get to it! Thanks.

*Edit*

Alright, sweet! I got it. I was close before, but forgot something crucial. I are dum!
