Explanation / Answer
here program asks user to make a guess of characters of a hidden word if user makes a correct guess of character then it displays that character with the position
here hidden word is pirate so the program asks to make a guess of character in word ??????
suppose you made a guess p then it will display p?????
again if you made a guess r then it will dispaly p?r???
program first declares hangman class
public class Hangman
then it declares
private String secretWord;
private String disguisedWord ="";
private String guessedLetters = "";
private int numberOfGuesses = 0;
private int numberOfIncorrectGuesses = 0;
here secretWord is the hidden word disguised word is used to display like ?????? or p?????
which is initially empty ""
guessedLetters is used to display total guessed characters like if you guessed characters v,n,c,d,s
then it will dispaly vncds
numberOfGuesses is used to count total number of guesses made and
numberOfIncorrectGuesses is used to count total number of incorrect guesses
rest i have commented the program if still you dont understand then just comment
public class Hangman {
private String secretWord;
private String disguisedWord =""; //used to form word ??????
private String guessedLetters = "";
private int numberOfGuesses = 0;
private int numberOfIncorrectGuesses = 0;
/*
* a constructor is a method that is called during creation of a object like ->
* Hangman hangman = new Hangman("pirate");
* here Hangman("pirate") calls the method below
* this is Hangman constructor it takes input string and forms a new string disguisedWord using the length of given string
* here secretWord is pirate length is 6 so Hangman constructor creates disguisedWord as ??????
